The Belesar arch dam, owned by Gas Natural Fenosa SLU, was built between 1957 and 1963 on the Miño River, north-west of Spain. The dam is 129 m high and impounds a reservoir of 655 hm³, used mainly for power generation. It is equipped with a bottom outlet (160 m³/s) at the central part of the dam body and two gated spillways, located at both gravity abutments (total capacity 4’000 m³/s). The total length of the dam crest is about 500 m, considering the arch (268 m) plus both abutments.
During the 1970’s, shortly after construction, permanent displacement towards upstream as well as vertical deformation of the dam body were noticed. In addition, a peripheral crack near to the foundation appeared at the downstream face. This phenomenon has been caused by and ARR reaction, producing an expansion of the dam body and a concrete swelling. The irreversible deformations have been increasing up to now with values of 10 cm in the radial direction at the dam crest, without reaching an equilibrium state so far.
After 50 years in service, Lombardi Ltd has been commissioned by Gas Natural Fenosa SLU to carry out a safety assessment of the dam, focussing on the expansive phenomenon due to the concrete alkali-silicate reactions. The expertise includes the evaluation for the medium-long term of the safety and operation conditions and the proposal of potential restauration measures, consisting probably of vertical slots using diamond wires to release the compressive stresses induced by the ARR reaction.


One of the envisaged development proposals of the project is the construction of a large dam on the Groot Letaba River at the Nwamitwa site, downstream of the confluence of the Nwanezi River. The proposed dam will
- cover a catchment area 1400 km2
- have a Mean Annual Runoff (MAR) of 122.6 million m3
- have a gross storage capacity of about 144 million m3 (final size to be determined)
- have an increase in system yield of 47 million m3/a (dependent on final size)
- have a capital cost of R490 million (1996 prices), including the realignment of R529 and other local roads.

Current South Park Conveyance study area; boundaries may change based on technical feasibility.
Seattle Public Utilities is currently working on three stormwater projects to reduce flooding in the lower industrial basin located in the northwestern part of South Park and improve water quality in the Lower Duwamish Waterway.
This project will complete preliminary design for a new stormwater collection system in roadways that don’t currently have one. Scope and budget will ultimately determine which roads SPU can construct new drainage systems for. Selected roadways will be rebuilt to ensure they drain into the new inlets and catch basins.
We are planning to construct the flood control pump station first to overcome the effects of high tide. We are also planning to build a water quality facility that will treat stormwater from the storm drain system before it flows into the Duwamish Waterway.
This project is supported in part with funding from the King County Flood Control District.
The South Park drainage improvement project is a joint effort with SDOT. The project is currently in the options analysis phase for design of the drainage system. The SPU team is working with a team of technical consultants to determine the best approach and sequencing for the planned improvements. In early 2017, outreach to the industrial area of South Park and directly impacted businesses/residents will gather feedback on the proposed plan and use this feedback to inform the options analysis and design phases.
SPU will analyze and plan drainage improvements for the entire project area. However, the 2016 – 2021 budget is not sufficient to complete all the work. The plan will include all the work, along with a phased approach for full implementation. The initial phase of construction will be based on available budget. The scope and schedule of the first phase will be determined as a part of the plan.
When complete, this project will work in tandem with the flood control pump station and water quality facility to reduce flooding in the industrial and residential areas in the northern part of South Park. The pipe improvements will collect and convey flows to the drainage system and lessen flooding in the right-of-way and on private properties. The conveyance system will also direct stormwater to the flood control pump station, which will pump stormwater to the Lower Duwamish Waterway, and to the future water quality facility.


OrangePit’s range of StrongCuttersuction Dredgers rely on both the cutting capacity of the cutter head together with the suction capacity of the dredging pump to dredge up the material and pump it to a reclamation site, hopper barge or sidecast location. By adding waterjets, the gathering production can be improved.
Cuttersuction dredgers compared to suction dredgers can dredge in more cohesive material like clays, compacted sands, compacted gravel and highly weathered rock and can be used to more accurately achieve a final required depth. Cuttersuction dredgers are used for sand winning purposes and for deepening or cleaning up canals, ponds, lakes and rivers. For deep suction applications our dredgers can be equipped with our submersible pumps.

Simmons Branch Drainage Improvement Project - Phase 2
- Storm Drainage System
- $5.6 million
- Stormwater Management (Lead)
- Dewberry (Design)
- Moffat Pipe, Inc. (Construction)
Posted Thursday, Jan. 4
The Stormwater Management Division has received approval to move forward with revised drainage improvements for both the Simmons Branch Phase II and the White Oak Lake project, which is a separate project that will follow approximately six months behind the construction of Simmons Branch. The reconstructed White Oak Lake will enhance the lake to reduce downstream flooding and meet infrastructure needs for the Simmons Branch Phase II project.
The revised project design for Simmons Branch Phase II includes replacing the current 700-foot concrete box culvert, which is located in the center of the project, and increasing the size of the Pineview Drive culverts and a private driveway bridge at 3605 Swift Drive to significantly reduce flooding to homes that are upstream.
The project was bid for construction in November and Raleigh City Council awarded the construction contract to Moffat Pipe, Inc. on January 2. Private utility relocation for the project is complete and all environmental permits have been received. Construction is expected to begin in February after the construction contract process is complete.
Several homes are experiencing first floor and garage flooding in the proximity of Pineview Drive and along Swift Drive, which are upstream of Lail Court, in flood events smaller than a 10-year flood. In addition, the existing box culvert along Swift Drive is undersized and in need of repair. The purpose of this project is to reduce street flooding on Swift Drive, minimize structural flooding of homes, eliminate channel bank erosion, and lower project costs. The final project will at a minimum meet the 10-year level and in some areas provide up to a 100-year level of service.
Channel stabilization measures have been incorporated into the design to prevent bank erosion and loss of private property due to high velocities of Swift Creek.
|Fall 2013||Phase I completed|
|Winter 2017||Phase II public meeting held & 30% design plan developed|
|Summer 2017||70% design plan, private utility relocation, permit application, easement acquisition, and construction plans complete|

As of Monday, May 6 increasing outflow from reservoirs in the Abitibi-Timiskaming region are causing Ottawa River levels to rapidly rise in the Mattawa area. Levels from Pembroke down to Lac Coulonge are expected to begin increasing as upstream flows arrive in these areas. Combined with rainfall of up to 25 mm expected to begin on Thursday over much of the watershed, peak levels should be reached along this upper river section on Wednesday through Friday depending on location.
Along the Ottawa River from Chats Lake down to Lac Deschenes, levels are expected to rise again but should not exceed the initial peaks observed last week. With warmer temperatures, reservoirs in the Abitibi-Timiskaming region are rapidly filling with increased snowmelt runoff. In this part of the watershed, the volume of spring runoff exceeds the capacity of most reservoirs and excess water will be released from the reservoirs once filled.
The Ottawa River level at Pembroke as reported by the Ottawa River Regulating Committee on Monday, May 6 at 2 p.m. was 113.33m. The peak level in 2017 was 113.03m. The forecasted peak is expected to be on Thursday, May 9 with a level of 113.60m. All levels are in reference to mean sea level.

Title: Numerical and Experimental Study of Axial Force and Hydraulic Performance in a Deep-Well Centrifugal Pump With Different Impeller Rear Shroud Radius
A multistage deep-well centrifugal pump (DCP) with different impeller rear shroud radius have been investigated both numerically and experimentally under multiconditons, which aims at studying the influence of impeller rear shroud radius to the axial force and pump hydraulic performance. During this study, a two-stage DCP equipped with three different impellers was simulated employing the commercial computational fluid dynamics (CFD) software ANYSY-Fluent to solve the Navier-Stokes equations for three-dimensional steady flow. High-quality structured grids were meshed on the whole computational domain. Test results were acquired by prototype experiments, and then compared with the predicted pump performance and axial force. The static pressure distribution in the pump passage obtained by numerical simulation was analyzed. The results indicated that the appropriate impeller rear shroud radius could improve the pump performance and lower the axial force significantly.

proHNS designed the first phase of this residential subdivision development, which constructed a 1,000-foot access road and sewer main from Hooter Lane to the project site. Our Engineer also calculated the capacity of the existing AK DOT&PF-owned drainage system on Glacier Highway at the bottom of Hooter Lane, the runoff of the existing drainage basin encompassing the location of the proposed development, and the runoff increase due to the proposed development. Staff subsequently used these calculations to develop a drainage plan addressing the increased runoff from the proposed development to meet CBJ and AK DOT&PF design standards. proHNS performed construction inspection of Phase I on behalf of CBJ.
We are currently designing Phase II, which will pave the roadway and install a water line, storm drain network, curb and gutter, and sidewalk.

Forging Lug Type Dual Plate Swing Check Valve
The check valve Working principle and characteristics: the function of the check valve is to control the one-way flow direction of the medium in the pipeline, so as to prevent the backflow of the medium in the pipeline. The utility model relates to an automatic valve which is automatically opened and closed by the force generated by the flow of the medium itself in the pipeline. It is used in the pipeline system, its main function is to prevent the reverse flow of the medium, to prevent the reverse rotation of the pump and its driving motor, and to discharge the medium in the container. The check valve belongs to the automatic valve class, the opening and closing parts open or close automatically by the force of the flowing medium. Check valve is only used in the pipeline with one-way flow of medium to prevent the return of medium to prevent accidents. It is mainly used in petroleum, chemical, pharmaceutical, chemical fertilizer, electric power and other pipelines.


River networks and estuaries are very common in coastal areas. Runoff from the upper stream interacts with tidal current from open sea in these two systems, leading to a complex hydrodynamics process. Therefore, it is necessary to consider the two systems as a whole to study the flow and suspended sediment transport. Firstly, a 1D model is established in the Pearl River network and a 3D model is applied in its estuary. As sufficient mass exchanges between the river network and its estuary, a strict mathematical relationship of water level at the interfaces can be adopted to couple the 1D model with the 3D model. By doing so, the coupled model does not need to have common nested grids. The river network exchanges the suspended sediment with its estuary by adding the continuity conditions at the interfaces. The coupled model is, respectively, calibrated in the dry season and the wet season. The results demonstrate that the coupled model works excellently in simulating water level and discharge. Although there are more errors in simulating suspended sediment concentration due to some reasons, the coupled model is still good enough to evaluate the suspended sediment transport in river network and estuary systems.

Fortis has announced the completion of the 335MW expansion of Waneta hydropower complex in British Columbia, Canada.
The $900m Waneta hydropower expansion project has been developed under a partnership between Fortis and Columbia Power and Columbia Basin Trust (CPCBT), which is wholly owned by the provincial government.
The Waneta Expansion project adds a second powerhouse, immediately downstream of the Waneta Dam on the Pend d’Oreille River, which shares the existing hydraulic head and generates clean, renewable, cost-effective power from water that would otherwise be spilled. It was completed six weeks ahead of schedule and on budget.
Work under the project included the construction of a 10km-long 230KV transmission line.
The development is located near the Waneta Dam on the Pend d’Oreille River. It generates enough energy to power approximately 60,000 homes annually.
BC Hydro and FortisBC will purchase the clean energy generated at the hydropower project, under a 40-year power purchase agreement.
Earlier in October 2010, HydroWorld.com reported that SNC-Lavalin had secured a $575.6m contract to design and build the Waneta expansion after Fortis concluded definitive agreements for the project with CPCBT earlier that month.
The Aecon Group was also appointed to work jointly with SNC-Lavalin on the plant’s construction later in November 2010.
Fortis owns a 51% stake in the project, while Columbia Power Corporation and Columbia Basin Trust hold a 32.5% and 16.5%share, respectively.

Griffin designed an eductor dewatering system, totaling 1800 ft., which included four (4) separate operating eductor pump stations. The systems were used to lower the piezometric water level to 17 ft. below existing grade. This was necessary for both the excavation of the existing coal residuals in the three existing ponds and for the construction of the new concrete holding basins that were built to replace those ponds. The material from the existing ponds was hauled off site for disposal.
The Griffin Difference:
Time was of the essence on the project and the Griffin Team mobilized and installed the system in just over 30 calendar days. The four individual systems were brought on line separately in a manner that allowed the Contractor to construct the two new concrete basins initially and then start removal of the CCR material from the existing lagoons.
The dewatering facilitated completion of the concrete basins, removal of the CCR from the existing ponds, and backfilling in a period of approximately 60 days from start to finish.


DAY TWO FIELD VISIT
Date 20 February 2016
Mumwemwe dam wall was raised and widened as a way of increasing the capacity. Stone pitching was done on both side and at the top to reduce cattle traction. 8 silt traps were constructed to reduce siltation of the dam. The dam benefits 425 households through water for livestock, domestic use and gardening When the project was visited there was low water level about 40%. The 2ha garden was not planted due to the low water level. Water is reserved for livestock since there is no other dam nearby. Mrs. Artzinger was happy to see the protected dam wall and that the project members were committed to complete the construction of silt traps.

Abstract: The present study aims to analyze the equilibrium scour morphology occurring downstream of rock-made sills with different shapes, under different inflow conditions. Namely, experimental tests were conducted under both steady and unsteady flow conditions. In this last case, the peak discharge was kept the same as the respective base tests performed for steady flow conditions. The scour evolution was carefully monitored, as well as the main characteristic lengths of the scour hole (e. g., maximum scour depth and axial length). The inflow discharge characteristics were varied, i. e., the maximum peak discharge was reached by adopting different hydrographs, in order to test their influence on the equilibrium morphology. Experimental results showed significant similitudes in terms of equilibrium scour morphology between steady and unsteady flow conditions when the hydrograph duration is enough long. The results of the present study can be useful for a correct design of such structure typology in usual applications.

A water distribution network model which was based on virtual reality was constructed and the state-of-art was simulated in a 3D scene. It works with a clear sense. The water network engineering database was built firstly in this paper to keep the precision of the 3D model. The water network model was constructed after the 3D models of the valves and pipes were made. The model was driven by the Vega and the simulation of the state-of-art was taken by the VC++MFC and EPANET software package. In conclusion, all kinds of data for water distribution network could be shown in the VR based simulation of the water distribution network directly. The topology linkage of the water network and the state-of-art analysis can be realized. The system overcomes the limitation of the traditional GIS system, and the simulation is exact and believable.

Brayman Construction Corporation has been awarded a US$15.2 million contract by the U.S. Army Corps of Engineers for civil construction of an emptying basin for Charleroi Locks and Dam on the Monongahela River at Charleroi, Pa.
The Corps’ Pittsburgh District most recently called for bids for the work in August.
Brayman Construction will fabricate large precast reinforced concrete segments to form the outer shell of a 50-foot by 110-foot emptying basin, according to Corps documents. Tremie concrete is to be used as infill for the shell to solidify the structure, which will be located downstream from the dam and riverward of the new lock chamber river wall.
With federal economic stimulus funding, the Pittsburgh District allotted $17.4 million in 2009 for critical rehabilitation of Charleroi Locks and Dam, also known as Monongahela Lock and Dam 4.

Flood Relief plans for Ballinasloe are progressing as consultant engineers are expected to be appointed for the project this week.
The €8.6 million flood relief scheme for Ballinasloe involves several major infrastructure upgrades to protect the town from flooding.
New flood defences under the relief scheme include 530m of walls and 5km of flood defence embankments, along with a demountable flood gate.
Two new flood alleviation arch culverts, each 6m wide, will also be installed at Ballinasloe East bridge, while landscaping works will be carried out
Other work included in the scheme are: two Lock Gates across the Canal and a sluice gate across the channel flowing into the marina from the canal, upgrade to the existing Kilclooney Road Bridge on the River Deerpark, along with work on the riverbed around the bridge and maintenance of the east and west channels to ensure their maximum efficiency in the event of a flood.
Galway TD Denis Naughten said that Minister for Public Works Kevin Boxer Moran is expected to make a formal announcement this week about the engineers’ appointment.
Their work will include “any environmental assessment, public consultation and to deliver the formal planning approval for the project,” said Denis Naughten.
Ballinalsoe will benefit from more than just works in the region of the town itself, as other flood relief works are taking place on the Shannon south of its juncture with the River Suck.
These relief works involve removing blockages in the river which “have a direct impact on flooding south of Ballinasloe,” Deputy Naughten said.
He added that other projects for east Galway are under consideration and, “further measures will take place along the River Shannon over the coming months which will have a direct impact on flooding problems along the River Suck and River Shannon.”


The station is located on the Tungnaá River and takes advantage of the drop between the tail water of the Hrauneyjafoss Power Station and the Sultartangi Reservoir. The head will is 40 metres, with a harnessed discharge of 280 m3/s and an installed capacity of 95 MW. The energy generating capacity of the Station is estimated at 585 GW/h annually.
The main proposal for the Búðarháls Power Station is to build two dams to the east of Búðarháls, a short distance above its junction with the Tungnaá River and the Kaldakvísl River. One of the dams will be built across the Kaldakvísl River and the other across the outflow from the Hrauneyjafoss Power Station. The dams will both be approximately 25 metres at their highest point but will vary in length; one of the dams will be 1100 metres in length and the other 170 metres.
The dams will form the intake reservoir for Búðarháls and will be given the name ‘Sporðalda Reservoir’, with an estimated surface area of some 7 km2. The reservoir will mainly fill the channel of Kaldakvísl and also extend slightly into Þóristungur. A headrace tunnel approximately 4 km long will be excavated from the intake structure at the Sporðalda Reservoir, westward under Búðarháls, to a surge basin by the Sultartangi Reservoir. Two 60 metre long, steel pressure pipes will transport the water from the intake to the station’s turbines. The powerhouse will be mostly above ground, built into the western side of the slope of Búðarháls.
There will be two 47.5 MW Kaplan generating units.
Energy from Búðarháls Power Station will be sent from the generator step up transformers, located in front of the station and then underground to the Landsnet substation, located to the south of the powerhouse. It will be transported from the substation, via high voltage line, eastward across Búðarháls to the Hrauneyjar line and onto the National grid.
There are six hydropower stations in the catchment area of Rivers Thjórsá and Tungnaá: Búrfell, Sultartangi, Hrauneyjafoss, Vatnsfell, Sigalda and Búdarháls, with combined energy of 935 MW. Water for all the power stations is provided by three main reservoirs, Thórisvatn, Hágöngulón and Kvíslarveita, along with smaller reservoirs connected with each station.
Lake Thórisvatn, Iceland’s largest lake, is the largest reservoir and an important part of Landsvirkjun’s utility system. All water accumulated in Kvíslarveita and Hágöngulón reservoirs runs through Lake Thórisvatn.
Lake Thórisvatn became a reservoir with the harnessing of River Thjórsá at Búrfell Mountain in 1970-1972. River Kaldakvísl was diverted into the lake at the northern edge of the lake and a controlled outflow constructed at the southern edge.
A canal was dug from the lake and a concrete gate structure built in the canal to manage the flow rate. The canal is named the Vatnsfell Canal, and carries water from Lake Thórisvatn through the Vatnsfell Station into the Krókslón Reservoir above the Sigalda Station, and from there to other stations further down in the catchment area.
Work on the Kvíslaveita Reservoir began in 1980 and was completed in 1997. Kvíslaveita is the collective name for the dams, canals, bottom outlets and gate structures that manage the flow rate from the River Thjórsá and its tributaries into Lake Thórisvatn.
The Háganga Reservoir was constructed in 1997–1999 and covers an area of 27 km2. Its purpose is to increase the efficiency of the catchment area of River Kaldakvísl. During the summer months, water accumulates in the Hágöngulón Reservoir, with very little water flowing down the Kaldakvísl riverbed.

The Dillon Reservoir is owned and operated by Denver Water, and is their largest water storage facility. The Reservoir has a capacity of 257,304 acre ft. (1 acre ft. = 325,851 gal.), and the Dam has a storage capacity of 254, 036 acre ft. Construction of the Dam began in 1961 and was completed in 1963. The entire town of Dillon, Colorado, and a hydroelectric plant were relocated to build the dam. Proceeds from recreation stay in Summit County for the management of recreational activities on the reservoir.


The £16.8 million pound project constructing a new reservoir adjacent to the site of the original reservoir at Ambergate, started in April 2014. Being commissioned over 100 years ago, the Victorian reservoir was nearing the end of its life.
Severn Trent Water invested twenty years in conducting studies as to whether to refurbish or replace the asset. Construction of a new reservoir was chosen as the best engineering and economic solution. NMCNomenca were chosen to replace the existing reservoir with two new structures, which together will increase the storage capacity of the reservoir.
The first structure built next to the existing reservoir measures 138m long and 100m wide. This will be able to store two-thirds of the required capacity for the completed project. When this is brought into service, the existing structure will be demolished and building works on the second reservoir will commence within its footprint. With 100,000m3 of material needed to be excavated over the life of the scheme, this will be designated and stockpiled for re-profiling of the site on completion.
As the contract neared completion and testing of the reservoir was undertaken including part filling the reservoir, it became evident that a number of construction joints were not fully sealed.
Churchill’s Enviro division were approached and awarded the contract to address these weak areas and seal the construction joints, which was successfully completed by Churchill’s leak sealing team.
