Taffeni Reservoir is a new 2.5Ml reinforced concrete reservoir cell which is expected to be commissioned at the end of 2020. This is the second phase augmentation of the Taffeni Reservoir (total 5Ml storage) where potable water will be able to supply the new Elaleni and Zululami Developments. The existing reservoir currently serves the Sheffield area and Brettenwood Development.
Bosch Projects was originally involved in the design and successful project implementation of the first 2.5Ml Taffeni Reservoir cell, high-level booster and its associated supply bulk supply pipelines back in 2009.
The new project includes large (355mm and 450mm diameter) HDPe bulk supply pipelines and a new high-level booster pumpstation building, which contains new mechanical and electrical equipment. It is projected that the project will be within budget.


In order to explore the influence of different wear-ring sizes on the performance and flow characteristic in a centrifugal pump, both numerical simulation and performance test are conducted in a centrifugal model pump. Two normal wear-ring clearances(0.25 mm and 0.50 mm)and an abnormal big gap(0.75 mm)are selected. By comparing the pump performance and flow characteristics at every clearance, the influence of wear-ring size on the performance and flow is obtained. It is shown that with increasing clearance both the pump head and the efficiency decrease. The radial thrust on the impeller reaches the largest at 0.50 mm gap, decreases at 0.25 mm, and eventually arrives at the smallest thrust at 0.75 mm. The total pressure is distributed more evenly in the axial cross-section of the wear-ring at a larger clearance. The total pressure near the side chamber decreases, but that near the impeller eye increases. Because of being affected by the centrifugal force on the shroud, the radial velocity magnitude and vorticity of the fluid in the chamber between the shroud and the casing increase gradually with increasing clearance, causing an even more smooth streamline pattern there.

Hydraulic model tests of the spillway of Yukar Kalekoy Dam and Hydroelectric Power Plant (HPP) were carried out at Hydromechanics Laboratory of Middle East Technical University (METU), Ankara. In order to investigate the flow conditions in the approach channel, over the weir structure, around the spillway piers, along the spillway chute channels and after the flip buckets, and also to observe the performance of the aeration devices, a model of 1/70 length scale was constructed. The model area covers an about 400 m x 450 m section of the Yukar Kalekoy reservoir, the whole spillway structure and a part of the river area of about 150 m x 200 m downstream of the flip buckets. Experiments were carried out at various discharges; QPMF, Q(1000) and Q(100) with fully open radial gates as well as with partly open radial gates at Q(1000). Flow depths, pressure heads of the flows along the spillway structure were measured, cavitation indexes and air concentrations of the flows were determined. From the observations and experimental results, it was concluded that the flow conditions in the approach channel of the spillway, over the weir structure, around the spillway piers, along and after the flip buckets are quite good from the hydraulics point of view. However, the flows were not sufficiently aerated in the spillway chutes, in Channels I and II, after the available aerators presented in the original design of the spillway. After the experiments conducted on the "original model" it was decided that some modifications should be done. In order to improve the performance of the available aerators, the heights of the aerator deflectors were increased by 0.20 m by keeping their lengths in the flow direction almost as before.

A soil-water balance model (SWB) was developed to estimate potential recharge and surface runoff for portions of the St. Louis River drainage basin, northeast Minnesota, for the period 1995 through 2010. The model was used in the creation of St. Louis River streamflow distribution maps, as part of the associated report, U.S. Geological Survey Scientific Investigations Map 2017-3390 (http://dx.doi.org/10.3133/SIM20173390). This SWB model was calibrated using three independent hydrograph separation models: PART, Hysep-fixed, and Hysep-sliding method. The basic framework for this model was the statewide Minnesota SWB potential recharge model, described, calibrated, and documented as part of U.S. Geological Survey Scientific Investigations Report 2015-5038 (http://dx.doi.org/10.3133/sir20155038). Daymet (version 2) daily surface weather data necessary for running this SWB model, including "prcp", "tmax", and "tmin", can be downloaded from an associated SWB model for the Cannon River drainage basin: https://doi.org/10.5066/F72V2DMN.

Area river towns are once again putting an eye to the state’s waterways. Following locally heavy rains and snow over the weekend, towns along the Mississippi and Illinois Rivers are going to be fighting on two fronts – flooding and the coronavirus.
Mayors from 10 communities in the Mississippi River corridor said this past Thursday that the capacity exists to respond to the anticipated spring storm impacts. According to the National Weather Service’s Advanced Hydrological Prediction Service, all of the measuring areas along the rivers are at minor flood stage this morning.
While many of the towns along the flood risk corridor expect flooding this spring, it is not predicted to be anywhere close to last year’s record flood stage marks. The Mississippi and Illinois Rivers are expected to sit above flood stage until at least April 2nd. Last year the river at Hardin set its second highest mark on record at 40.24 feet. The Illinois River at Meredosia sat its 4th highest mark ever last year at 28.4 feet.

The presentation of the project "Rehabilitation of the concrete dam Mandak on Lake Mandak," near Lake Buško Blato in Livno, BIH, took place last week.
Our collegues Krunoslav Mavar & Mia Raič from IGH regional centre Zagreb, with the presence of Tomislav Marić, presented and defended the rehabilitation project to representatives of the Investor HEP-Proizvodnja from Split, Croatia and Crpne stanice Buško Blato .
The Concrete dam Mandak is classified as a medium-sized dam, which was built in 1967, in the bed of the river of the same name. The dam consists of nine concrete blocks, with a reinforced concrete bridge above the spillway fields. The height of the concrete dam is 31.30 m, while the length of the dam is 99.69 m.
The conclusion of the project review is that the project is well-designed and accepted. With some adopted remarks, it will serve as a quality basis for carrying out rehabilitation works that will contribute to improving the mechanical resistance and stability, and prolonging the lifespan of the structure. Rehabilitation works on the dam are planned to be carried out in the forthcoming period, thereby reducing future losses, increasing the functionality of the installed equipment, facilitating traffic across the dam, as well as enhancing the aesthetic appearance of the hydro-technical structure.

The Bogan Shire Council has received $10.2 million to improve water infrastructure in the shire.
The funding from the NSW government is expected to further improve the shire's water infrastructure, including the construction of a second storage dam to almost double the current water holding capacity.
Included in the funding is $8.2 million for the construction of a second water storage at Nyngan expected to hold over 500ML, with construction planned to start in the second half of this year.
It will complement the existing storage which is currently holding 500ML of emergency water supply for Nyngan and Cobar, to be used if water is no longer available from Lake Burrendong.
The funding also includes:
$750,000 to replace the Belaringar Creek Syphon on the Albert Priest channel
$950,000 to survey and repair leaks in the Albert Priest channel bed
$20,000 for the installation of a temporary weir south of the main Nyngan water supply weir
$250,000 to investigate potential bore sites east of Nyngan to supplement the town's water supply


The fourth and final phase of the £16 million South West Inverness flood relief channel works is almost complete.
The scheme aims to protect 600 houses which are at risk of flooding on the south side of Inverness. The work intercepts five water courses including Cuduthel channel Lochardil burn, Slackbuie channel, Slackbuie springs and Alt na Skiah burn.
This final phase of the project began in November 2011 with the contract awarded to main contractor RJ McLeod Contractors Limited. The works are being supervised by The Highland Council’s TEC Services site team and the contract designers are Leeds-based AECOM. The project is due to be completed in December 2012.
The total length of construction for Phase Four is 1,400 metres and extends from Lochardil burn to Ault Na Skiah. Approximately half of this will be buried precast concrete box culverts, the remainder will be open channel.
A spokesman for Highland Council said:
“We are now working on a number of fronts to complete the installation of buried concrete box sections adjacent to Slackbuie distributor road and adjacent to housing at Upper Slackbuie.
“In addition we are completing the works on open channel constructions and the intake structure in Ault na Skiah Burn above Fairways Golf Course.”
Phase One of the project commenced at the River Ness and travels up the Holm Burn to Holm Burn Bridge. The works included increasing the capacity of Holm Burn, the widening and deepening of an existing sediment pond, and the replacement of two bridges.
Phase Two involved construction of the confluence at Holm Burn, sedimentation pond and weir to catch sediment from the channel prior to its discharge into the Holm Burn. A combination of culverted sections and open channel were constructed from the Holm Burn confluence to Culduthel Channel.
Phase three was a combination of culverted sections and open channel, beginning at Culduthel Channel and ended at Lochardil Burn, Old town of Leys.
Works have also been completed to replace the B862 Holm Burn Bridge as part of the scheme. This replacement means the bridge is wider and flood capacity of the bridge is increased. Developers are also funding the provision of a cycleway to access a proposed adjacent development.
The project is one of three flood alleviation schemes currently undertaken by Highland Council. The others involve work on the River Ness and Mill Burn.

Non-regulated the MH 250/100 pump motors is used in drilling rigs, in deisel locomotive manufacturing, diesel trains. The pump motor MH 250/100 works in two modes: hydromotor and non-regulated pump. MH 250/100 is the previous MH 250/160 model and therefore the pump motor MH 250/160 without any revamping is freely replaced. There is practically no difference between them.
The pump motors MH 250/100 are subdivided into 2 look:
In delivery with valve box (the valve box intends for overload protection of hydraulic system in which the pump motor is installed);
and the pump motor 1MH 250/100 in delivery without valve box.


Run-of-river hydropower plants usually lack significant storage capacity; therefore, the more adequate control strategy would consist of keeping a constant water level at the intake pond in order to harness the maximum amount of energy from the river flow or to reduce the surface flooded in the head pond. In this paper, a standard PI control system of a run-of-river diversion hydropower plant with surge tank and a spillway in the head pond that evacuates part of the river flow plant is studied. A stability analysis based on the Routh-Hurwitz criterion is carried out and a practical criterion for tuning the gains of the PI controller is proposed. Conclusions about the head pond and surge tank areas are drawn from the stability analysis. Finally, this criterion is applied to a real hydropower plant in design state; the importance of considering the spillway dimensions and turbine characteristic curves for adequate tuning of the controller gains is highlighted.


Amador cruise port construction begins
The Panama Maritime Authority (AMP) has begun construction of the Amador cruise port with a kick-off ceremony.
A cruise terminal will be built at Perico Island over the next 18 months on the Pacific side of Panama.
It will have two docks in which two cruise ships with a capacity of up to 5,000 passengers each (Oasis-class) can berth simultaneously.
The design and construction of the terminal was awarded by the AMP to the Cruceros del Pacifico consortium, which includes Jan De Nul Panama and the China Harbor Engineering Company (CHEC).
Jan De Nul will undertake all dredging and land reclamation works, including dredging the berth pocket, turning basin and access channel with a backhoe dredger and trailing suction hopper dredger (TSHD).
A TSHD will be used to transport sand from a borrow area and reclaim an area of 8.3 hectares for the construction of all land-based facilities.

Lake Ogallala Water Level Lowered for NPPD Maintenance Project
In coordination with the Nebraska Public Power District (NPPD), Central began draining Lake Ogallala in late September to allow NPPD to complete maintenance on the Keystone Diversion Dam as well as other canal maintenance projects.
Beginning on Sept. 22, no water has been released from Lake McConaughy through Kingsley Dam into Lake Ogallala. The project is expected to last until late November, resulting in nearly two months of no water being released out of Lake McConaughy. While the lake is drained, crews will be reapplying a protective coating to the gates on the south side of the Keystone Diversion Dam, which helps regulate the amount of water released from Lake Ogallala into the North Platte River.
To prepare for the construction, Central built a dike near the Kingsley Dam to protect the infrastructure of the Kingsley Hydroplant.

The Casper-Alcova Irrigation District (CAID) provides essential water delivery through canals and other irrigation infrastructure to over 23,500 acres of irrigated land in Central Wyoming. Over the years, WLC has had the opportunity to provide civil engineering, surveying, and construction materials testing on several projects associated with CAID. In 2021, WLC was hired to provide civil engineering design and construction contract administration for the 102 Overflow Check Structure Rehabilitation project. This project was completed in April 2022.
Built in the 1930’s as part of the Kendrick Project, the concrete structure is located on the main Casper-Alcova irrigation canal and is intended to discharge the entire volume of the main canal into an existing drainage in the event of a canal failure downstream of the structure. An evaluation of the structure identified several large cracks on the underside of the canal and a deficiency in the overflow gates operation. After several configurations were evaluated for flow capacity, constructability, and cost, WLC concluded the check structure was in good condition and able to be rehabilitated.
WLC’s final designs consisted of a 10’x3’ reinforced concrete box culvert under drain, two 8’x6’ slide gates for the overflow control, and 10’x19’ reinforced concrete box culverts for the discharge side of the structure. Completion of this project provides the CAID reliability and peace of mind for a critical piece of their irrigation infrastructure.

Forecasting of flows, overflow volumes, water levels, etc. in drainage systems can be applied in real time control of drainage systems in the future climate in order to fully utilize system capacity and thus save possible construction costs. An online system for forecasting flows and water levels in a small urban catchment has been developed. The forecast is based on application of radar rainfall data, which by a correlation based technique, is extrapolated with a lead time up to two hours. The runoff forecast in the drainage system is based on a fully distributed MOUSE model which is auto-calibrated on flow measurements in order to produce the best possible forecast for the drainage system at all times. The system shows great potential for the implementation of real time control in drainage systems and forecasting flows and water levels.

The forebay is a regulating reservoir which stores water under reduced load conditions and provides water when the load increases.
Details and Construction
The forebay is a wide water body whose major function is storage of water. Depending on low, medium, or high heads its construction and working can be different. Its design and location also depends on various circumstances and can be different under different conditions.
In Low head plants
Usually, a dam is constructed on the river and a canal is constructed for diverting water to a forebay. The water is then sent from forebay to the turbines.
In Medium Head Plants
Here the water from the river is tapped off to the forebay from which it proceeds to penstock and then moves to turbines. In medium dams, the forebay serves as another surge tank.
Similar to read: Role of the Surge tank in close conduit dams
Forebay in High Head Power Plants
In high head plants, the powerhouses are located far away from the storage reservoir. In such cases, forebay is another smaller reservoir constructed downstream of the main reservoir. The powerhouse takes water from it
The above cases are general cases, depending on local conditions the construction of the structure and its application might vary and should be decided by power crew on that station.

Dworshak Dam began construction in 1966, and the main structure was completed in 1972. The generators came online in 1973. It is a hydroelectric gravity dam located in Clearwater County of Idaho. It was originally slated to be named "Bruces Eddy," but the named was change to honor Senator Henry C. Dworshak.
Dworshak Dam is the highest straight-axis concrete dam in the Western Hemisphere, and the 22nd highest dam in the world. There are only two other dams in the United States that exceed it in height.
The Generating capacity is 400 Megawatts, with an overload capacity of 460 MW. The dam has two spillway gates. It is part of the Columbia River Basin system of dams.
Dworshak Reservoir is the body of water behind the dam. The lake stretches 53 miles upstream. The North Fork of the Clearwater River runs two miles downstream from the base of the dam, until it joins the South Fork of the Clearwater, which flows to the Snake River.


At least 960 megawatts will be added to the country’s power network in June this year, with the launch of the second power station of the Cambambe Hydroelectric Dam in Cuanza Norte province. According to the Minister of Energy and Water, João Baptista Borges, the second Cambambe power station will generate the equivalent of twice the current capacity of the Capanda Dam, in Malanje province.
Regarding the Laúca Hydroelectric Dam, currently under construction in the Cuanza Norte province, the minister said that it is expected that the first two turbines of the dam start operations in June 2017 and generate 267 megawatts. The last turbine will start operations in December the same year and generate 77 megawatts.
As for Soyo’s combined cycle power generation plant, a project designed to produce electricity from natural gas, it will start to generate electricity in 2017 with a total output of 750 megawatts.

The proposed project involves construction of pumping station and related facilities at the present drainage gate of the north bund of Kelani ganga flood protection scheme. Part of the Kelaniya DS divisional area is subjected to frequent flooding. This is caused to various kind of damages and losses of the properties of the people in the area. Flooding is caused by local drainages are blocked when the Kelani River is higher level to prevent the river water coming in. Therefore this local flooding problem could be mitigated only by pumping. By this project it is expected flood mitigation of 33 hec. of highly developed land area and annual saving of about 5 million worth people properties. Total project cost is Rs. 310 million.
Action has been taken to settle the people in the project area.
Allocation for the year 2016 is Rs. 50.00 mn.


Experiments are carried out to determine the effects of different inlet geometries on the onset of suction recirculation and its associated power consumption in an axial-flow pump. The critical flow rate is determined by both the “string” visual technique and “pressure” method. The results are correlated with the inlet area and flow velocity distribution upstream of the impeller. Four different conical covers matching the impeller leading edge are employed to cover the impeller inlet completely or partially. Covering the inlet area reduces the critical flowrate corresponding to the onset of suction recirculation and eliminates all recirculation at higher flowrates. The power consumption associated with the suction recirculation flow for the uncovered impeller is determined by comparing the shaft powers with and without inlet covers. At the shut-off condition, the power is estimated from a comparison with the shaft power measured with the impeller inlet completely covered. Experimental studies conclude that the power consumption due to suction recirculation is mainly controlled by the impeller inlet area and is insensitive to the inlet pipe configuration. At shut-off condition, the power coefficient correlates well with the parameter based on the hydraulic radius of inlet area. At a finite through flowrate the analytical model recommended by Tuzson (1983) is adequate, except for a proportionality coefficient determined from the test data.

The proposed BVL Outfall Project will maximize stormwater discharge and create a new positive outfall by constructing dual 8’ x 6’ box culverts and additional canal improvements further upstream to help move the water towards the new outfall. The dual 8’ x 6’ box culverts will convey water from a pond within Buenaventura Lakes to the east side of Simpson Road. A ditch will be constructed from the terminus of the box culverts to the lake. These improvements are anticipated to remove 142 homes from flooding during the modeled 100-year storm event. Design and permit submission is complete. The County is currently seeking federal grant funds for the construction of this project.


According to the national standard GB/T 2816 submersible pump well standard, the water temperature is 25℃, rated as the current, the cable voltage should not exceed 5% of the rated voltage.
The cable specification of submersible pump is determined by the heating and pressure drop of the cable. In addition to the need to control a certain current density to limit the temperature rise of the cable, the longer the length of the cable, the greater the voltage drop of the submersible pump cable, and the greater the impact on the starting performance, operating performance and reliability of the motor. Therefore, for the motor with submersible pump in the same well, when the submersible pump head is different and the length of the cable is different, the requirements on the cable section are also different.
According to the standard of well submersible pump, when the power supply voltage is 380V, the maximum allowable length of submersible pump motor is the same as a certain power line. When the power supply voltage is higher and more stable or relatively large power transformer capacity, the higher the voltage, more stable, Wells with submersible pump motor is equipped with the same specifications of the cable allow depending on the specific situation to the appropriate length (or the cable is reduced, in order to reduce the cost of cable configuration), the maximum allowable length of submersible pump cable installation of submersible pump motor has a regulation.
When the submersible pump motor, according to well depth, along the cable length is longer, the poor quality of power supply transformer, motor start-up difficulties: starting current is very big, long the pressure drop of the cable, reduce the voltage of the motor, the starting current is added, submersible pump cables of the pressure drop is larger, lower starting torque, create a vicious cycle, motor start is difficult, not only forced to start may cause damage to the motor windings. Therefore, each submersible pump must be equipped with submersible pump cable as required.

BY OBERT SIAMILANDU
THE Zambezi River Authority (ZRA) yesterday said the rise in water levels in the Kariba Dam catchment area would result in uninterrupted water allocation for power generation for both Zimbabwe and Zambia.
In a statement, ZRA chief executive officer Munyaradzi Munodawafa said the authority had maintained its 30 billion cubic metres (BCM) water allocation for power generation projects at Kariba Dam after the Meteorological Services Department projected normal to above normal rainfall patterns for the 2020/21 season.
“However, the authority continues to monitor the evolving hydrological situation under the Kariba catchment.
