Acceptable flood capacity safety upgrade of the Moogerah Dam, Australia
Estimates of design floods have increased since the Moogerah Dam was designed and as a result, the owner is now required to invest in an upgrade of the dam’s flood capacity.
Aurecon was engaged by Seqwater to conduct an investigation into an Acceptable Flood Capacity (AFC) safety upgrade of the dam, which is located near Boonah, south-west of Brisbane.
Moogerah Dam is a 40 metre high double curvature arch dam with gravity thrust blocks on each abutment. A free overflow ogee crest spillway is located on the right abutment of the dam. The existing spillway capacity has been previously assessed as being inadequate and so the dam needs to be upgraded to comply with safety requirements set by the Queensland dam safety regulator, Department of Energy and Water Supply, (DEWS).
Aurecon, in association with Entura (Hydro Tasmania), undertook a two stage geotechnical site investigation to define input parameters for the upgrade design by constructing a geotechnical model of the dam and its foundations.
The investigation was separated into two stages to ensure that unnecessary fieldwork was not undertaken and to reduce overall costs for the project. The staging of the investigations allowed the progression of the dam engineering and geotechnical modelling to proceed in partnership.
Options that were considered to increase the flood capacity of the dam included widening of the existing spillway, raising the dam crest and allowing the overtopping of the dam crest by provision of foundation and toe protection works.
The project team identified a range of flexible solutions that will ensure the safety upgrade can be staged to satisfy the timeframe imposed by DEWS.
In addition to design flow estimates, Aurecon undertook a Monte Carlo simulation to support an informed design process. The outcomes of this assessment provided the owner and designers with an understanding of the sensitivity of the critical design flow estimates to hydrological inputs and ultimately the sensitivity of design requirements. This guided the owner in directing investment to components of the upgrade leading to maximum benefit.

The Ancholme Internal Drainage Board was formed in 1951 under the Land Drainage Act 1930. The Board’s purpose was to protect people and their property against river and surface water flooding through water level management within low lying areas along the River Ancholme Valley.
Earliest records of the “Old River Ancholme” date back to 1287. The canalised “New River Ancholme” received commission by enactment in 1825 and was completed around 1844 with John Rennie appointed as Engineer.
Due to the flat gradient of the New River Ancholme and controlled water level from Ferriby Sluice, up to 50% of the Drainage District relies upon mechanical means of lifting water from the low lying areas into the New River Ancholme. Approximately 5% of the Drainage District is mechanically lifted into the River Humber to overcome siltation from tidal flows constantly affecting gravity discharge.


The Keswick Waste Water Treatment Plant expansion involved the construction of several new treatment structures including a headworks building, aeration tank, clarifiers, biofilter building and others. The challenge presented at the project was to control a shallow aquifer with relatively low flows as well as a lower aquifer with high flows.
INSITU successfully completed the dewatering of the upper aquifer with a combination of vacuum wellpoints and deep wells. At the peak of construction, INSITU was pumping about 7,500 liters per minute to lower the water table to a sufficient depth below the excavation base to allow for a dry excavation.
- Large volume dewatering project involving various dewatering methods for waste water treatment
- Successful installation of high capacity wells to depths of approximately 30-m
- Able to maintain performance of wells with backup systems used during station power shut downs and unanticipated power outages

A temporary steel construction wall placed at the site to aid installation of the new Lake Delhi Dam failed June 14.
High water flow on the Maquoketa River is being blamed for the incident, during which the steel construction wall broke away from the concrete wall behind it. Heavy rain last week resulted in flash flooding in eastern Iowa.
The area of the failure was about 10 feet wide in a wall that is about 350 feet long.
The original Lake Delhi Dam failed in July 2010 after two days of heavy rain and the lake was drained and has since sat empty.
At the time of the failure, floodwaters were 25,000 to 30,000 cubic feet per second. The new dam and spillway should be able to handle flows as high as 69,000 cfs.
The Lake Delhi Combined Recreational Facility & Water Quality Board made a unanimous decision to rebuild the dam in February 2014.
This work, to be conducted in two phases, included rebuilding of the dam and construction of public access points. Total cost of the project was expected to be about US$16 million.
Before this most recent incident, construction of the replacement dam was scheduled to be complete by the end of October.
The original dam was completed in 1927 and included a small hydropower project until the 1970s. There have been discussions about adding a 1.5-MW powerhouse at the dam, although we are not aware of any decision having been made.

Other major project components include the powerhouse construction, concrete spillways, approximately 2.2km of earthen dam structures, 23km of earthen dike structures with a fill volume of 4.3 million square metres, borrow-material sources and boat docking and launching facilities. The project will require placement of 360,000m³ of concrete.
The scope of works under the GCC include rock excavation, pouring of concrete for the powerhouse and spillway, construction of the earthen structures, electrical and mechanical work, and the construction of temporary cofferdams to manage the river flow during construction followed by the removal of the cofferdams after completion.
Preliminary construction works for the project started in 2012 and are dubbed as Keeyask Infrastructure Project. The works involve the construction of access roads and a site camp for 2,000 people, being built on a 129ha site on the northern side of the river.
Details of the hydroelectric power plant
The hydroelectric power plant will feature seven Voith Hydro units with an operating head of 19m. The turbines will be of the fixed blade propeller type, with a rated capacity of 99MW per unit.
Darlington Nuclear Generating Station (DNGS) is located in Clarington, within the Regional Municipality of Durham, in the Province of Ontario.
Earth fill dams include the North Dam, the Central Dam and the South Dam, which will be founded on bed rock. The elevation of the dams’ crest will be approximately 162m, while the height of the dams will range from 19.5m and 28m.
Earth fill dikes include the North Dike and the South Dike, with crest elevations ranging from 161.8m to 163m, and heights of 20m and 30m respectively. A roadway will also be constructed on top of the dikes.
The project will create a reservoir area of 93km² by flooding a land area of approximately 45km².
The seven-bay spillway with motorised vertical lift gates will be designed to handle a probable maximum flood of 11,300m³/s. A permanent roadway bridge will be constructed on top of the spillway.
Transmission lines for the Manitoba project
A 22km transmission line will be laid to provide power to the site during the construction phase. It will be connected to the existing 138kV transmission line located south of the project site.
Three transmission lines measuring approximately 35km will be laid within a single corridor to transfer the power generated from the new plant to the existing Radisson Converter Station near Gillam, from where it will be distributed for use in Manitoba and for sale to Wisconsin Public Service in the US.
Key players involved in the project
Britco has been awarded a $207m contract to build the site camp and is carrying out the works in two phases. The first phase, expected to be completed by June 2014, will provide accommodation for 500 people, while the second phase will involve the construction of the remaining rooms to accommodate 1,500 people.

The reservoir’s water source comes from two main rivers: The Tasoh River and the Pelarit River.
Combined, both have a catchment area that totals 191 km2 and is capable of supplying approximately 97 million m3 of water into the reservoir annually. One of the reservoir’s main purposes is to create a water supply system for agricultural use—i.e. for the cultivation of paddies, domestic drinking water and irrigation purposes. It also acts to control and mitigate flooding during the rainy seasons. The Timah Tasoh West Flood Diversion Project serves to mitigate the flooding issues in Northern Perlis.
The project involves the construction of flood-bypass canals and a limestone tunnel measuring 756 in length. The flood-bypass canals will ease the water discharge during heavy rains. Overflow water from the reservoir will be diverted from the flood-bypass canals to Perlis River and finally to the Straits of Malacca.
This will also benefit the farming industry because the diverted overflow water can be used for agricultural purposes. Maccaferri was involved in this Agribusiness project during the construction of the flood-bypass canal along Kampung Wai near Kuala Perlis. The canal cuts through a hill where it eventually encounters a double sided rock slope along the canal passageway. Loose and fractured rock on the slope could damage the canal if not protected.
Maccaferri aided the client, JPS Kangar by designing a solution using Maccaferri Steelgrid MO. Steelgrid MO is easy to install and effective for the protection of the canal from rock hazards. Now, the rock surface is stabilized and provides a safe access along the canal.

Contractors have moved on site on two flood alleviation schemes in Lincolnshire.
Machinery has moved on site at Louth to build embankments
The projects are designed to help manage the flow of the River Lud and River Bain.
Both schemes are being carried out by VBA, a joint venture of VolkerStevin, Boskalis Westminster and Atkins. They form part of the Environment Agency’s water and environment management (WEM) Framework.
The £6.5m Louth flood alleviation scheme will see two flood storage areas constructed outside the town, with embankments of 150 metres and 200 metres. Once built, these storage areas will reduce the risk of flooding from the river Lud.
An £8.1m scheme at Horncastle involves the construction of an 800-metre temporary flood storage area, which will hold up to 1.3 million cubic metres of flood water from the River Bain.
Both schemes are funded by a partnership of Lincolnshire County Council, the Environment Agency, East Lindsey District Council, and the Lindsey Marsh and Witham Third Internal Drainage Boards.
“As part of the schemes we will be installing ground-breaking flow control structures, which have never been installed in the UK before and is something the VBA team is especially proud to pioneer,” said VBA senior project manager Steven Hammer.

Stop valve ( globe valve), also known as stop valve, belongs to forced sealing valve and is one of the most widely used valves. The stop valve relies on the pressure of the valve rod to make the sealing surface of the valve disc closely fit the sealing surface of the valve seat and prevent the flow of medium, because only one-way flow of medium is allowed.
The opening or closing stroke of the valve rod of the stop valve is relatively short, and has a reliable cutting function. At the same time, the change of the valve seat opening is in direct proportion to the stroke of the valve disc, which is suitable for the regulation of flow. Therefore, this type of valve is very suitable for cut-off or regulation and throttling.
Fluid closing is the main goal of gate valve, and flow throttling is the main goal of stop valve.
The fluid regulation capacity of the gate valve is poor and there is no Gate valves do not create a pressure drop in the pipeline, as do globe valves Stop valves open faster than gate valves.

56th and Colfax Storm Drain Project
The Havelock Salt Creek Watershed has been studied and analyzed to determine deficiencies in the existing stormwater system. The drainage study completed a hydrologic and hydraulic analysis for both the minor events (5-year and 10-year) and major event (100-year) throughout the watershed. Several locations were identified for proposed projects to address the deficient drainage systems.
The stormwater system located along Colfax Avenue between Touzalin Avenue and N. 56th Street was determined to be undersized for the drainage area flowing toward the system. The existing system consists of storm sewer inlets and a 42-inch trunk line that cannot convey the flows for this area. Two different alternatives to increase the capacity of the trunk line were analyzed and a preferred alignment was selected to proceed toward final design. Cost, feasibility, and effectiveness will all be factors in selecting the final design route. The selected alignment includes leaving the existing 42-inch pipe in place and adding a new 6-foot x 4-foot concrete box culvert north of the existing pipe along the David Murdock Trail. The new box culvert will increase the overall storm drain capacity in the area to help alleviate the deficiencies. Also as part of this project, the David Murdock Trail will be upgraded from a crushed limestone trail to a 10' wide concrete trail.

Chinese Begin Work on Uganda’s $500M Hydropower Plant
China International Water Electric (CWE) has commenced construction work on the 183-megawatt Isimba Falls hydropower plant, situated on the Ugandan stretch of the White Nile approximately 40 kilometres downstream from the Bujagali Power Station.
The project is expected to increase Uganda’s total installed electricity capacity by around 23 per cent, generating 1,039 gigawatt/hours of electricity annually at a rate of 68 cents per kilowatt/hour.
The project will feature four 45.8-megawatt Kaplan hydro turbines and will be connected to the Bujagali Power Station via a 132-kilovolt power transmission line.
Ugandan media reported in July that the contract for the construction of the hydropower plant had been awarded to China International Water and Electric Corporation, a Chinese state-owned power company under the aegis of the China Three Gorges Corporation.
The project is also being funded by Chinese parties, with the China Export and Import Bank, a state-owned entity, providing a concessional line for its construction.
Construction work on the project is scheduled to continue for 34 months, and upon completion Isimba Falls is set to be the fourth largest hydropower project in Uganda, following the 250-megawatt Bujagali power project, which commenced operation last year; and the 600-megawatt Karuma Dam and 600-megawatt Ayago power station.
The project serves to significantly further China’s already highly extensive involvement in Uganda’s hydropower sector.
The $2.2 billion Karuma project, which commenced construction in September and is expected to be Uganda’s largest hydropower plant upon completion, is also being built and funded by Chinese parties.
Ugandan President Yoweri Museveni met personally with Chinese President Xi Jinping at the fifth BRICS Summit in Durban, South Africa in March to secure funding for the Karuma hydropower plant.
In return for Chinese funding for the project, Uganda agreed to award the contract for Karuma’s construction to China’s Sinahydro, another state-owned engineering and construction company which is headquartered in Beijing.

Home » Shop » 2006 – Design and Construction of the Gattonvale Offstream Storage
Nerida Bartlett, David Scriven, Peter Richardson
The failure of a number of consecutive wet seasons has resulted in storage levels in Eungella Dam being at dangerously low levels such that supply could be exhausted by June 2007. Eungella Dam supplies bulk water to the Bowen Basin coal fields as well as the Collinsville power station and the Collinsville township.
The Collinsville township, power station and coal mine as well as the Newlands mines take water from the Bowen River Weir which is supplied from Eungella Dam some 95 kilometres upstream. Transmission losses of the order of 25 to 50% have been experienced for releases from Eungella Dam to Bowen River Weir.
The Eungella Dam catchment area is 142 square kilometres. Significant flows occur in the Bowen River downstream of Eungella Dam, the catchment area above Bowen River Weir being 4,520 square kilometres. The topography in the surrounding area (near Collinsville) is not suitable for dam construction.
The opportunity existed for the construction of an offstream storage adjacent to the Bowen River Weir so that the downstream flows could be captured reducing the demand on Eungella Dam thus making more water available for upstream users.
A 5,200 ML offstream storage, associated pump station and rising main was designed, constructed and filled within a period of 12 months.
Foundations at the site are highly permeable sands. Marginally suitable clay for a seal was in short supply as was suitable rock for slope protection. A fixed price budget had been set by the contributing customers.
This paper describes the hydrology, site conditions, design and construction of the project.

Willow River area dam set to be replaced
January 1, 2021
Residents and visitors to the Stanton Lake area on the Willow River will see increased levels of construction activity and truck traffic in the coming weeks as the damaged Willow River dam is removed and is replaced with a rock arch rapids. The dam, built in the 1940s, breached in July 2016 after a large flood overtopped the dam and eroded the adjacent embankment.
Earlier this month, workers temporarily diverted the river channel and dewatered the work area so they could remove the failed concrete dam. In the next phase of construction — expected to last into February — a series of step...

The key parts of the submerged pump are as follows. Now, the details are as follows:
(1) Impeller is the core part of submerged pump.
According to its mechanical structure, it can be divided into three types: closed type, semi closed type and open type. Closed impeller is suitable for cleaning liquid of conveyor; semi closed impeller and open impeller are suitable for mixing liquid with solid particles of conveyor, and the high efficiency of this pump is low.
According to different suction methods, impeller can be divided into single suction and double suction. The single suction impeller is simple in structure, and the liquid can only be sucked in from one side. The double suction impeller can absorb the liquid symmetrically from both sides of the impeller. It not only has a great capacity of suction, but also mostly removes the radial thrust.
According to the geometry shape of the blade on the impeller, the blade can be divided into three types: backward bending, axial bending and forward bending. Because the mechanical energy of the backward curved blade is beneficial to the transformation of the liquid into the negative pressure energy, it is widely used; the axial blade is used in a part of the flow pump and the non blocking pump; the forward curved blade is rarely used in the submerged pump.
(2) The guide vane and pump casing can reduce the kinetic energy damage caused by the impact of the liquid leaving the impeller entering the pump casing immediately. Sometimes, the equipment has a fixed guide vane between the impeller and pump casing. The vane in the guide wheel makes the liquid entering the pump shell slowly turn into and continuously expand through the flow passage, so that part of the mechanical energy can be reasonably transformed into negative pressure energy. The guide wheel is generally installed for multi-stage submerged pump.
The small tortoise shaped pump shell, the backward curved blade on the impeller and the guide wheel can improve the conversion rate of mechanical energy to negative pressure energy, so they can be regarded as energy conversion equipment.
(3) The shaft seal equipment is fixed because of the rotation of the pump shaft, so there must be a certain gap between the shaft and the pump shell. In order to prevent the high pressure liquid in the pump from exposing along the gap, or to prevent the external gas from entering the pump in the opposite direction, it is necessary to set the shaft seal equipment. The shaft seal equipment of submerged pump has the sealing property of stuffing box and mechanical equipment (inner hole). The stuffing box is a sealing ring made by passing the pump shaft through the ring gap of the pump housing, in which soft packing (such as oil immersion or asbestos rope coated with high-purity graphite, etc.) is installed. The mechanical seal is composed of a moving ring installed on the transmission shaft and another static ring fixed on the pump housing. The inner holes of the two rings rotate relative to each other closely by elastic yellow force, which has the sealing effect. Machine seal is applicable to places with high sealing requirements, such as conveyor acid, alkali, inflammable, flammable, explosive and harmful liquid.


Snohomish County is scheduled to replace the existing culvert in the 19900 block of Jim Creek Rd, east of Arlington, during summer 2021. The existing six-foot by six-foot concrete culvert has been deemed a fish-passage barrier. The project will replace the culvert with a single 21-foot steel arch culvert.
Construction for this project is scheduled for July through the beginning of September 2021.
Traffic will be reduced to a single lane during construction. The single lane will be controlled by temporary traffic signals.
Construction for this project is estimated at $900,000 and will be funded through the Surface Water Management Utility Fund and the Road Fund.

Two hydropower plants with a total capacity of 63MW are expected to come up on the Western Dvina and Vitebsk. Two more plants, having a total capacity of 37MW, will be built on the Neman River. Additionally, ten existing hydropower plants will be restored, and 35 new ones constructed. The plants are expected to produce up to 600 million kWh of electricity. The country has identified 1,840 potential wind sites, which have a total capacity of 1,600MW. Plans are afoot to build a 160MW wind farm in Dzerzhinsk district, Minsk Oblast between 2011 and 2014. In 2009, the country had a total installed capacity of 1.2MW.


The standard models of pumping stations are intended for pumping clean water at a temperature of 25°C and their maximum operating pressure must not exceed 1.0 MPa (max. operating pressure is the sum of the head pressures of the pump with the rate of delivery and water pressure at 0 in the suction pipeline – this value cannot be greater than 1.0 MPa). The pumping stations are supplied from an open balance tank (or from several tanks).
They are equipped with two to six pumps (horizontal pumps are used). The pumps are mounted on concrete, properly reinforced foundations. Each pump is fitted with non-return valves and cut-off fittings at the inlet and outlet. The pumps are connected to the suction and discharge manifolds, which are fitted with necessary sensors, pressure gauges and pressure vessels. The control system is mounted within a cabinet or several cabinets mounted on pedestals. The pumping stations are equipped with dry run protection, selected depending on the water supply method and requirements of the Client.
Basic models include the following types of pumping stations:
ZH NK – with NK pumps from Grundfos
ZH ETM – with ETANORM pumps from KSB
ZH OMG – with OMEGA pumps from KSB
There are three basic types of control system:
“SPE”: the so-called multiple inverter system where every pump is equipped with its own inverter. Pressure downstream of the unit is adjusted smoothly – steplessly.
“SP”: this control system uses frequency converter to adjust the rotational speed of one pump of the pressure boosting unit. In this version, the converter is automatically switched to other pumps of the system in the right order (the so-called “rotating” converter). Pressure downstream of the unit is adjusted smoothly – steplessly.
“K”: a cascade (threshold/time varying) control system where pumps maintain pressure within set pressure thresholds (P min – P max).
Custom models of water pumping stations
In addition to the standard models, Firma Bartosz manufactures special models of pumping systems. Exemplary custom solutions:
- models for the following pressure ratings: PN 16, PN 25, PN 40,
- models for hot water,
- models for contaminated water,
- models for other media, such as: demineralised water, glycol, saline water, solutions of detergents and cleaning agents, as well as solutions of certain aggressive liquids,
- multi-section units: with fire pump(s); mud pump(s); jockey pump(s); booster pump(s),
- units with additional equipment, such as: bypass for pump testing; backup bypass, priming pumps for the units
- units operation monitoring: possibility of using serial communication through MPI connection, enabling wired communication (Profibus, Modbus, Ethernet); communication using radio modems, modems and telephone network, including GSM; visualization panels based on software such as, among others: Wonderware InTouch, Inntellution IFIX, Siemens WinCC, Emation Axeda Supervisor, Rockwell Software RSView 32, etc.
- use of drivers: Siemens, GE Fanuc, Schneider, SAIA, Allen-Bradley, Unitronics and other,
use of frequency converters: Danfoss, ABB, Siemens, Schneider, Lenze and other.

Two-phase Flow Type and Pressure Drop Characteristics Research in Porous Media Channel
YANG Xiao-ming;SUN Bin;Zhai Dong-xu;Energy Resources and Power Engineering College Northeast Dianli University;China Guodian Jilin Jiangnan Co-generation Co.,ltd;
A high-speed video camera was used to study the flow patterns in the porous media channel of vertical upward flow. Four kinds of typical flow patterns were identified within the parameters in this experiment,they were bubbly flow,slug flow,pulse flow and mist flow. Based on the pressure drop data of two-phase flow which obtained in the experiment,pressure drop relationship of sub-phase model and homogeneous model were fitted respectively and two types of resistance relationship have been obtained which adapted to the characteristics of this experiment. The improved model of two types have all reached a good agreement with the experimental data,but the homogeneous model which contained various influencing factors to the pressure drop in its defined relationship has higher prediction accuracy compared with the sub-phase model,and the physical meaning of the homogeneous model was more clearly,so the model could be used for calculated the resistance of the gas-liquid two-phase flow in the porous media channel in the first place.

Carmel River Reroute and San Clemente Dam Removal Project, United States of America
The Carmel River Reroute and San Clemente Dam (CRRDR) project is the largest dam removal project in California and the West Coast of US.
The project includes the removal of San Clemente Dam located on the Carmel River in Monterey County, and re-routing a 3,000ft section of the Carmel River into the San Clemente Creek River.
The project received the California Public Utilities Commission's (CPUC) approval in June 2012. The Monterey County Planning Commission (MCPC) approved the project in May 2013.
California American Water (CAW) is the owner and operator of the dam, with URS Corp as its representative. CAW appointed Water Systems Consulting (WSC) as the project manager.
Construction works for the project began in 2013 and are expected to be completed by July 2015.
Financing the major dam removal project
The $84m project is being developed through a Public Private Partnership (PPP).
California American Water (CAW or Cal-Am) will provide $49m, while California State Coastal Conservancy (CSCC) and National Marine Fisheries Service (NMFC) will jointly provide an additional $35m from PPP sources.
The project is being supported by environmental organisations such as the Carmel River Watershed Conservancy and the Carmel River Steelhead Association. Nature Conservancy, a non-profit organisation, provided $1m for the project.
The project will also be funded by the California Department of Fish & Game, California Natural Resources Agency, California Wildlife Conservation Board and United States Fish & Wildlife Service.
Carmel River Reroute and San Clemente Dam history
The 106ft high San Clemente Dam is a concrete arch dam which was constructed in 1921. The dam initially had a 1,425acre-feet reservoir storage capacity. The storage capacity declined over the years owing to the huge amount of sediments totalling about 2.5 million cubic yards, almost covering about 90% of the entire water storage space.
The reduced storage capacity of the dam forced the authorities to remove it from the Monterey region's water supply system in 2008.
The California Department of Water Resources (CDWR) Division of the Safety of Dams (DSOD) issued a safety order for the public, in the 1990s, that the dam will possibly fall in the event of an earthquake or probable maximum flood (PMF).
CDWR issued a Draft Environmental Impact Report (EIR) for the San Clemente Dam Seismic Safety Project (SCDSSP), which provided five solutions for the dam safety issue in 2006. The report included an idea of strengthening the dam, as well as removal including the current CRRDR project.
The dam strengthening idea was considered to be costly and could not provide the solution to the issue of removing the huge amount of sediment from the dam. The CRRDR project was considered as a better option.
The final EIR for the CRRDR project was received by CDWR in December 2007. The project received CDWR approval in February 2008. The CAW finally signed a deal with the federal government of the US to demolish the dam in 2010.
Details of the CRRDR project
The San Clemente dam is located at the meeting edge of the Carmel River and San Clemente Creek. The two rivers are further separated by a narrow ridge.
The Carmel River reservoir side stores majority of sediments. The CRRDR project will transfer the Carmel River sediments into a permanent sediment storage area, thus resolving the problem of excavating the huge amount of sediment from the dam. It will also reduce the project cost and will be environmentally beneficial.
The Carmel River will then be rerouted to the San Clemente Creek River, which will move the meeting point of the rivers upstream by half a mile. The up streaming of the meeting point will help in keeping the sediment area as it is. The sediment area is expected to be developed into a vegetated landscape.
The project will also involve cutting of a reroute channel to achieve the re-routing of rivers. The re-route channel will help divert the river flow from the sediment disposal area.
A new 400ft long diversion dike will be constructed using earth-fill material, in order to divert the river towards the new reroute channel. The dike will have a height of 45ft to 50ft. It will also have a seepage cutoff wall connected to the bedrock of the river.
The preliminary design of the dike is being developed by URS Corp. The dike will also feature a wedge-shaped slope that will be 700ft long and 70ft tall. The slope will be constructed upstream of the dam to store the sediments in the reservoir.
The sediments removed from the reservoir will be stored behind the stabilised sediment slope. The dam will be removed in stages once the construction of the dike and slope are completed. The partial removal of the dam is anticipated to begin in 2014 while the full removal is scheduled for mid 2015.
The half-mile reach on the San Clemente Creek reservoir side will be rebuilt to allow the combined passage of the river and the creek waters. Step pools will be created, by placing rocks across the channel's bottom, to allow passage of fish through the reservoir. Fishes can rest on the rocks at the time of jumping into the river.
Development of new access road, relocation of fish and other wild life, and geotechnical investigations were completed during the first phase of construction, which also included the preparation of the 68-acre construction site and partial construction of the Carmel River diversion system.
The permanent routing of the Carmel River to an alternate course that bypasses the 2.5 million cubic yards of sediment is expected to be completed during the phase season of construction that began in May 2014.
Benefits of the dam removal and river reroute project
The project will provide public safety by averting dangers from a possible fall of the dam caused by an earthquake or lightning which is estimated to affect 1,500 homes downstream. It will also restore the natural sediments and reduce channel incision and beach erosion.
The project will also provide suitable habitation for endangered species of California, such as the steel cut fish and the red legged frog. It will support habitation under the river by transferring the sediment naturally downstream.
Contractors involved with the CRRDR project
The State Coastal Conservancy (SCC) manages the PPP scheme of the project and represents the project design, construction and permitting decisions to the funding partners. The SCC formed a Technical Review Team (TRT) of experts to analyse technical aspects of the project.
The main contractor for the project is Granite Construction, which received a $61m design-build contract from Cal-Am in May 2013. The contractual scope includes the removal of the dam and development of the new reroute channel.
CAW will transfer 928 acres of land after the dam's removal to the US Department of Interior's Bureau of Land Management (BLM). BLM is collaborating with the Monterey Peninsula Regional Parks District (MPRPD) to develop public access and recreation facilities on the land.
Calaveras Dam Replacement Project involves construction of a new earth and rock fill dam to replace the existing seismically unsafe dam and avoid flooding downstream.
The US Army Corps of Engineers (USACE) completed foundation remediation works for the Wolf Creek Dam in March 2013.

This automatic pump controller eliminates the need for any manual switching of pumps installed for the purpose of pumping water from a reservoir to an overhead tank (refer Fig.1). It automatically switches on the pump when the water level in the tank falls below a certain low-level (L), provided the water level in the reservoir is above a certain level (R). Subsequently, as the water level in the tank rises to an upper level (M), the pump is switched off automatically. The pump is turned on again only when the water level again falls below level L in the tank, provided the level in the reservoir is above R. This automated action continues.
Pump Controller Circuit
The circuit is designed to ‘overlook’ the transient oscillations of the water level which would otherwise cause the logic to change its state rapidly and unnecessarily. The circuit uses a single CMOS chip (CD4001) for logic processing.
No use of any moving electro-mechanical parts in the water-level sensor has been made. This ensures quick response, no wear and tear, and no mechanical failures. The circuit diagram is shown in Fig.2. The device performed satisfactorily on a test run in conjunction with a 0.5 HP motor and pump.
The sensors used in the circuit can be any two conducting probes, preferably resistant to electrolytic corrosion. For instance, in the simplest case, a properly sealed audio jack can be used to work as the sensor.
The circuit can also be used as a constant fluid level maintainer. For this purpose the probes M and L are brought very close to each other to ensure that the fluid level is maintained within the M and L levels.
The advantage of this system is that it can be used in tanks/reservoirs of any capacity whatsoever. However, the circuit cannot be used for purely non-conducting fluids. For non-conducting fluids, some modifications need to be made in the fluid level sensors. The circuit can however be kept intact.

Boskalis Signs Major Duqm Port Deal
The Special Economic Zone Authority in Duqm (SEZAD) and Boskalis Westminster (Oman) LLC today signed an agreement for the construction of the liquid Bulk Berth Project at Duqm Port.
The new agreement, worth approximately $517 million, prepares Duqm Port to export liquid refined products and enhance its value in national economy.
According to the agreement, Boskalis will carry out detailed engineering designs, construction of marine infrastructure, dredging and reclamation works, while Worley Parsons Engineering will oversee the engineering and construction works of the project scheduled to be ready within 32 months from the date of awarding.
Under the deal, 2.4 km of the 4.6 km of secondary wave breakwater will be developed and reclaimed for the construction of the liquid quay, and the dual berth marina will be constructed with accessories and navigation equipment.
The project calls for the excavation of approx 26 million cubic meters of material in order to deepen the port’s basin and channel to 18 meters. About 5 million cubic meters of the material will be used to reclaim and fill the site dedicated to the quay.
The agreement also provides for the construction of the 1 kilometer quay wall and installation of buoys and navigational devices.


Tsurumi has unveiled the highest-flow versions of its HS Series pumps with the new HS3.75SL (manual) and the HSZ3.75SL (automatic) submersible, trash pump models.
Designed to handle high volume drainage at low head, the new models pump roughly twice as much water as the high head model HS3.75S for dewatering applications.
The new pumps offer a maximum flow rate of 140 GPM and maximum total dynamic head of 40 ft, with a motor input of just 0.75 kW. Compact and lightweight, the pumps’ wear parts are built from highly durable materials. The shaft incorporates Tsurumi's original agitator to prevent air lock and to stir slurry efficiently.
The difference between the two models is that the HSZ3.75SL contains a simple float switch-equipped automatic sensorto prevent dry-running operation and to reduce power consumption, which makes it appropriate for night-time operations and construction works in dense residential areas.
Glenn Wieczorek, managing director of Tsurumi America, said: “These trash pumps handle debris, sand and solids that come in flooding water with minimum wear and clogging.”

The Performance of Side Weirs at the Fishways
Proceedings of the International Symposium on Fishways '95
The Organizing Committee for International Symposium on Fishways '95 in Gifu
The aim of this paper is the investigation of the performance of side weirs at the fishways. Side weirs have been used extensively for water level control in canal systems of fishways as a means of diverting excess water into relief channels for protection works of fishways. The general differential equation of the water surface profile along the side weir in rectangular canals is derived by means of the energy equation. The conditional sampling technique allowed to obtain instantaneous profiles of the above hydrodynamical quantity which illuminated the physical picture of the flow over a side weir.
