This study develops a real-time near-optimal pump scheduling model for water transmission networks. The model aims to minimize energy cost by means of optimal pump operation while meeting system demands and satisfying operational constraints. The real-time control is realized using Supervisory Control and Data Acquisition (SCADA) system, by which system monitoring data is collected and the optimal control decisions are sent to the pumping stations for implementation. The model is composed of three simulation modules, such as demand forecasting, hydraulic simulation, and optimization. Decision variables include pump on/off (binary code of 0/1) schedules for fixed-rate pumps for each time-step over pre-defined operation time horizon. Various operational constraints are embedded in the model reflecting real operational practices. The proposed optimization model is demonstrated using a real, medium-sized water transmission system in Seoul, South Korea and showed 19~27% energy cost savings compared to a conventional operation scheme.

Albania: Report on Devoll hydropower project, SEE Energy News
Devoll hydropower project includes the construction of two HPPs: Banja and Moglice, which should be built in Devoll valley and have combined power output of 256 MW with projected annual electricity generation of 729 GWh, thus increasing Albanian electricity production by some 17 %.
Devoll hydropower project hit a major milestone on 15 April, as the filling of Banja accumulation started. Speaking at the ceremony held to celebrate the completion of the accumulation filling, Albanian Minister of Energy and Industry Damian Gjiknuri said that this project will guarantee the future of Albanian electricity production.
Minister Gjiknuri reminded that after the completion of Banja dam and filling of the reservoir, this project envisages the construction of another dam and accumulation, adding that he believes that Norwegian Statkraft will complete the project on time. Banja accumulation should be 16 kilometers long and should hold about 391 billion liters of water. HPP Banja will be ready for commercial operation as soon as the filling of the reservoir is completed and trial operation is successfully performed.

Detention rockfill dams are generally known as economic and efficient structural methods for flood mitigation and watershed management. Despite the existing studies in the context of rockfill dam design, designers still rely on time-consuming and costly experimental tests which can only lead into practical guidelines. Moreover, investigation of various rockfill dam design alternatives in terms of hydraulic performance needs an exhaustive framework to obtain the optimal design values. With respect to these, this research study aims to investigate the optimal dam thickness and mean diameter of coarse aggregates in detention rockfill dams in order to improve the hydraulic characteristics, e.g., reduction in flood peak discharge and increase in flood duration while the construction cost is minimized. Here, a methodology based on data-driven simulation model, multi-objective optimization model, multi-criterion decision making model, and social choice method is suggested to find the optimal design parameters of detention rockfill dam. This methodology adapts data to model and model to optimum design variables. Experimental results are converted to data-driven simulation model based on multilayer perceptron neural network, which can model the relationship between design variables of detention rockfill dam and parameters of flood hydrograph. The simulation model is used in a robust multi-objective optimization algorithm, non-dominated sorting genetic algorithm-ΙΙ (NSGA-ΙΙ), to establish a trade-off between the conflicting objectives. Eventually, PROMETHEE decision making model and Borda count social choice method are used to find the best agreed-upon design optimal point on the trade-off curve. Results indicate that the best non-dominated solution can be considered as 10.01 and 5 cm for the optimum thickness of detention rockfill dam and optimum mean diameter of coarse aggregates in the porous media, respectively. The similar optimum characteristics of detention rockfill dam using PROMETHEE and Borda count social choice method depict the stable performance of the proposed methodology.

What is pressure drop in heat exchanger？
Any kinds of the heat exchanger in the process of heat transfer. The medium will have a certain resistance when flowing through the heat exchanger, the medium outlet pressure is lower than the original inlet pressure, and the pressure difference between the inlet and outlet media is It is the pressure drop of the heat exchanger. In order to enhance the heat transfer, we will set some spoiler elements in the flow channel to increase the degree of turbulence and enhance the heat transfer, so the pressure drop will be greater during the strengthening process. The power required is even bigger, so the pressure drop must not be made too large. In order to consider cost and benefit and energy loss, an allowable pressure drop is proposed to limit the pressure drop to a certain range.

Mississippi River Forum: The Value of Open Space
Jenna Fletcher, Project Manager
Did You Know?
At Lake Onalaska, near LaCrosse WI, the Mississippi River is about 4 miles wide. The combination of water held behind Lock and Dam #7 and water held by damming the Black River form this broad reach of the Mississippi River.


Project Description & Outcomes
The proposed project diverts flow from an existing ditch system in the Highway 35 drainage area, through a pre-treatment cell, and then diffuses the flow into the wetland complex located on the Tax Forfeit property owned by the Comfort Lake-Forest Lake Watershed District (CLFLWD). The proposed project will result in annual phosphorus reductions of 89 lb/yr to the Sunrise River and 65 lb/yr to Comfort Lake which ultimately drains to the St. Croix River through the Sunrise River (these estimates were updated from the original concept and are based on the final project design). The project will also provide increased wildlife habitat and add 18.3 acre-ft of flood storage to the area.
The project will be constructed on the CLFLWD-owned property and will not impact any of the properties along the drainage ditch or those adjacent to the project area.
The proposed project was identified for targeted implementation through the District’s 2012 Sunrise River Water Quality and Flowage Project Engineer’s Report, the District’s 2012-2021 Watershed Management Plan, and the 2010 CLFLWD Six Lakes Total Maximum Daily Load Study. View the Feasibility Study for more information on the project. This is one of the resulting projects from the 2010 Chisago County petition.

Significant work is set to begin at the location of Tanzania Electric Supply Company Limited’s (TANESCO) 180-MW Kihansi hydropower plant.
Multiple tenders for equipment supply for the existing Kihansi plant were issued in mid-January. These included supply of complete deflector servomotor assembly and servomotor assembly for main injector, as well as upgrading of the excitation system for Units 1, 2 and 3. In November 2017, TANESCO issued a tender for consultancy services for design of the main valve cylinder gate for these three units.
Kihansi is located on the Kilombero river system along the Udzungwa escarpment, about 200 km southwest of TANESCO’s 204-MW Kidatu hydropower plant. A low concrete gravity dam diverts the river flow into a vertical unlined intake shaft 500 m deep that connects to an unlined headrace tunnel leading to a steel penstock. The powerhouse is in an underground cavern and contains three Pelton turbine-generator units each with a capacity of 60 MW. It was commissioned in December 1999.
TANESCO intends to add two 60-MW turbine-generator units and a large water storage dam to increase installed capacity at the site to 300 MW.
This work was detailed in a recent document on new and ongoing power projects to be implemented up to 2017, as extension of the Upper Kihansi Hydro Power Plant. It is being undertaken “to improve the power supply condition in Tanzania and create an opportunity for bilateral electricity trade with neighboring countries.”
TANESCO’s generation system consists of mainly hydro and thermal generation. The company has seven hydro plants with a total capacity of 561.845 MW and a total generation capacity of 1,135.61 MW.
Other recent hydro activity in Tanzania includes advancement of the 2,100-MW Rufiji project, located in the Selous Game Reserve.


Following similar work in Kain, the weir and lock complex is being completely modernised in Herinnes. This will ensure that the water level of the Scheldt remains suitable for shipping. The interventions are part of the European Seine-Scheldt project, which is intended to facilitate inland waterway transport on busy rivers in northern Europe.
Hydroelectric power plant provides its own energy supply
The old lock complex at Kain, which was built in the 1920s, could no longer meet contemporary requirements. A new water channel was excavated for the modern weir, which has a 1.65-metre waterfall and two 12-metre wide weir channels. A hydroelectric power station with a capacity of over 1,000 MWh/year was built on the site of the old structure, and the lock thoroughly renovated at the same time. The Hérinnes project is almost identical to that carried out at Kain.
ENGIE Fabricom’s role
ENGIE Fabricom is supplying and installing the electrical and electromechanical equipment for both the new weir and modernisation work on the existing lock. We are resorting to virtually every kind of waterway technical equipment currently relevant and available for these projects, such as:
- a hydroelectric power plant (three large Archimedes’ screws)
- mechanical and hydraulic equipment, more specifically for the dam
- power current and LV current
- automation and supervision
The works mainly concern the delivery and installation of:
- the two valves which move the new dam (cylinders and their connections, pipes, hydraulic units)
- the valve hinge bearings (supply only)
- the three hydrodynamic screws and associated control valves for the hydroelectric power plant
- the overhead crane in the hydroelectric power station building
- the transformer station
- the emergency generator
- the main LV switchboards
- the electrical installation in the control building
- the electrical wiring of the entire site
- the outdoor lighting
- the control system (sensors, PLCs, control panel) for the entire lock, dam and hydroelectric power station
- intercom system, VHF and river signs
- fibre-optic connection
At Hérinnes, we also installed a 2.5-km long HV line to the Schelde bridge in Warcoing.


Costain has started works on a £30m scheme to replace Ambergate reservoir.
The 110M Litres covered reservoir of Ambergate in Derbyshire, Europe’s second largest, has reached the end of its lifespan.
It’s a key strategic reservoir for Severn Trent Water as about 590,000 customers from the East Midlands currently benefit from it.
The large contractor Costain has
won the contract and will replace the reservoir by constructing two new reservoirs totalling 137M Litres.
A larger reservoir of 87M Litres will be built around the foundations of the old reservoir and once commissioned a new reservoir of 50M Litres will be installed in place of the old old.
As part of the project a concrete batching plant and junction improvements will be built.

Due to the structural characteristics of the long and slender horizontal hydraulic cylinder, it is prone to flexural deformation and instability under the effect of its own gravity and axial load, which may cause great safety hazards. This paper aims to design a test platform suitable for the flexural stability test of long and slender horizontal hydraulic cylinders. First of all, the model of large hydraulic cylinder is scaled down according to the modeling theory. The calculation method and finite element analysis method are used to simulate the deflection of the model, while simulating, the model hydraulic cylinder is regarded as the stepped rod. According to the calculated results, the overall scheme of the test platform is designed. And further, the platform structure design is completed. Finally, the finite element analysis software is used to assist the strength check. Through the design calculation and strength check in the paper, a hydraulic cylinder deflection test platform suitable for different strokes and bore diameters. The structure of the test platform is stable and reliable, and it is also convenient for assembly and disassembly.

Design of Flood Control Improvements by Systems Analysis: A Case Study.
HYDROLOGIC ENGINEERING CENTER DAVIS CA
Pagination or Media Count:
A hydrologic-economic simulation model was developed to evaluate alternative protection schemes in the design of an authorized federal flood control project for 125 miles of the Tibbee River flood plain in Mississippi. The model requires input consisting of unit hydrographs, streamflow routing coefficients and storage functions, a pattern storm, rainfall loss rate functions, and flow-damage-frequency relations. A single synthetic pattern storm was used in conjunction with flow-frequency curves at index locations to generate a series of floods for comparing alternative protection schemes with existing conditions. The effect of channel improvements on flood runoff characteristics was evaluated by using storage routing functions that account for changes in storage-discharge relations. Based on results obtained from using the model, a channel improvement plan was tentatively selected for the Tibbee River basin from the alternative schemes evaluated. Author

Construction on Crystal Dam began in mid-1973 and continued through August 1976 when the dam was topped out. Like Morrow Point Dam, Crystal Dam is a double-curvature, thin-arch concrete structure. Crystal Dam is located six miles downstream of Morrow Point Dam, and approximately two miles above the eastern boundary of the Black Canyon of the Gunnison National Park.
Crystal Dam serves an important function in stabilizing the flows of the Gunnison River to benefit the downstream environment, particularly the Black Canyon of the Gunnison National Park, as well as the production of hydroelectric power. Crystal Dam can be seen from the end of the East Portal road which begins just past the south rim entrance station at Black Canyon of the Gunnison National Park.
Crystal Dam stands 323 feet (98 meters) above the streambed, with a crest length of 635 feet (194 meters) and contains 154,400 cubic yards (118,047 cubic meters) of concrete. Water from the reservoir is released through the turbines of the powerplant, but during flood periods when the reservoir level exceeds full pool at elevation 6,755, water can pass over the ungated spillway. Crystal Powerplant contains one generating unit with a total capacity of 32 megawatts.
Crystal Reservoir extends six miles (10 kilometers) to Morrow Point Dam, and covers an area of about 340 acres (138 hectares). When Crystal Reservoir is full, it has a capacity of about 26,000 acre-feet (32 million cubic meters). Just downstream from Crystal Dam is the Gunnison Tunnel, the historic diversion for the Uncompahgre Project. The Black Canyon of the Gunnison National Park is located immediately downstream from the tunnel, and stretches 14 miles (23 kilometers) along the Gunnison River.

Gopeng Dam is situated about 600m from Gopeng town on the upstream stretch of Sg. Gopeng. Gopeng Dam was constructed in 1961 by JPS with purpose to retain mine tailings which otherwise would enter the river channel raising the bed level thus causing flooding of adjacent roads and towns. Presently the upstream area has completely silted up and the dam been reduced to tun-of-the river conditions.
A recommendation to decommission Gopeng Dam has been made through a report by the Dam Monitoring Unit, JPS in November 1990. By decommissioning Gopeng Dam, the Department can be relieved of the continuous burden of managing a dam which is no longer serving any meaningful purpose.


Hagley contracted CGC Geoservices to perform the restoration of the dam and adjacent millrace. Construction of the spillway restoration began in July during the typical seasonal low flow period. Adjustments were made to the design as necessary based on the actual conditions uncovered during construction as well as to deal with the challenges of construction in the middle of the Brandywine River during what ended up being an unseasonably wet Ssummer and fall construction period, requiring ontinuous innovation in the construction approach.
The project included dewatering of sections of the dam to allow evaluation and repair, placement of large boulders, riprap and concrete in the middle of the river, reconstruction of masonry walls, maintenance of sediment and erosion controls throughout the project, and vegetative restoration of the stream banks in a natural river setting.The dam restoration was successfully completed within budget and with minimum disruption to the surrounding historic and natural setting.
This project was recognized with multiple awards including theNew Castle County Historic Preservation Award for Industrial Technology Restoration and the Construction Excellence Award for the State of Delaware and the Delaware Contractors Association.

Dam Safety Improvement Program
SunWater is undertaking a safety improvement program to ensure the highest level of safety for our dams is maintained.
Our safety improvement program will ensure our dams continue to be able to hold and safely release excess volumes of water during periods of extreme rainfall and satisfy modern standards.
A detailed assessment of SunWater (and its subsidiaries) dams was undertaken to determine a prioritised list of dams requiring safety improvements. Dams were assessed on the following features:
- Current rainfall event capacity
- Affected populations
- Integrity of the dam structure under increased water loads
- Impact to the provision of ongoing water supply
- The economic impact of the dam’s failure during an extreme rainfall event
- Overall failure risks
Following this assessment, a prioritised improvement program was developed.
To date, the following dams have undergone safety improvements:
- Fred Haigh Dam near Gin Gin (Stage 1 completed 2006)
- Bjelke-Petersen Dam near Murgon (completed 2008)
- Borumba Dam near Imbil (transferred to Seqwater July 2008; completed 2009)
- Tinaroo Falls Dam near Mareeba (completed 2011)
- Kinchant Dam near Eton (Stage 1 completed 2015)
- Eungella Dam near Mackay (Stage 1 completed 2015)
A number of other SunWater dams and storages will undergo safety improvements in the longer term:

In addition to the safety improvement program, SunWater continues to undertake an extensive maintenance program for all dams.
Fred Haigh Dam
The first stage of the safety improvement was completed in September 2006. Identified as the highest priority improvement, the top of the dam was raised by constructing a two metre high wall and providing a watertight gate to allow operational access to SunWater’s Monduran Pump Station. The second stage of the safety improvement will be undertaken in the future.
Identified as the second highest priority safety improvement, work on the first stage commenced in February 2007 and was completed by October 2007. The main dam and saddle dam wall were both raised by 1.2 metres and the saddle dam wall was extended.
Identified as the third highest priority safety improvement, work commenced in April 2008 and was completed in March 2009. The Borumba Dam safety improvement involved increasing the height of the dam wall by 1.6 metres, allowing the dam to hold excess water until it can pass safely through the spillway. Ownership of Borumba Dam was transferred from SunWater to Seqwater 1 July 2008.
Tinaroo Falls Dam
Identified as the fourth highest priority safety improvement, construction commenced in March 2009 and was completed in 2011. The improvement to Tinaroo Falls Dam included work on both the main dam wall and the saddle dam.
The main dam wall was reinforced with the insertion of steel cable “anchors” within the wall and the addition of a concrete protection slab along the downstream base of the dam wall.
In addition to work on the main dam wall, the height of the saddle dam was increased by 30cm and “filters zones”, designed to minimise damage caused by seepage during a flood event, was placed on the downstream face.
The safety improvement of Kinchant Dam involved the installation of improved and extended downstream filters on the embankment. It also involved an upgrade of the existing drainage system within the structure itself, together with the installation of additional drainage within and downstream of the foundation of the dam.
Construction of the Kinchant Dam Safety Improvement Project commenced in June 2012 and was completed in March 2015.
The safety improvement of Eungella Dam involved reinforcement of the spillway crest with the installation of "anchors". The Eungella Safety Improvement Project commenced in late August 2015 and was completed in late September 2015.
The safety improvement of the Fairbairn Dam spillway will involve works on the lower chute floor including: the modification of drainage outlets; the repair and replacement of blocked drains; the replacement of steel anchors; the filling of voids under the concrete slabs of the spillway; and construction of a mass reinforced concrete overlay.
The safety improvement works are scheduled to commence in April 2016 and are due for completion in November 2016. More information is available here.
Burdekin Falls Dam
The safety improvement of Burdekin Falls Dam will be completed in three parts (Stages 1a, 1b and 2). Stage 1 involves installing additional drains and improving efficiency of current drains in the spillway and anchoring the rock foundation. A later Stage 2 would involve raising of saddle dams and strengthening the spillway monoliths.
A business case will be prepared for funding of each dam safety improvement project and those will be reviewed on a case-by-case basis.

Analysis of Fluid Flow in Screw Pump Based on ANSYS
In order to complete the numerical simulation on internal flow and operating characteristics of down hole multiphase pump compress unit, establishing perfect finite element model, the three-dimensional turbulent current fields inside the impellers of compression unit for down hole multiphase pumps were simulated by using ANSYS. The calculation of multiphase flow is based on the standard k-ε turbulent current model. Reference information for the improvement of the pump can be obtained by the analysis of the flow of gas-oil in the channel of pump. Based on the finite method, we analyzed several situations in a pumping period. The velocity and liquid pressure distributing of sucker rod pump is studied in this paper, which may offer some evidences for the engineering design of sucker rod pump.

Q2. INTRODUCING HYDEL POWER HIGHLIGHT THE HYDEL POWER PROJECTS IN PAKISTAN.
WHICH HYDEL POWER PROJECTS OF PAKISTAN HAVE BEEN PLAYING CONSTRUCTIVE ROLE IN GENERATION OF ELECTRICITY? EXPLAIN.
Pakistan possesses 30000 MW generating capacity of hydel power which is the cheapest source of energy. Fortunately, rivers flowing in Pakistan get water from the rice melted on the mountains therefore, these are the perennial rivers which have water whole of the year. Most of the hydel power projects are located in the North Western part of the country.
Prior to inception of Pakistan there were two hydel power projects here: one was established in 1925 at Ronala having capacity of one MW and the other was established at Mala Kand in 1938 with a generating capacity of 20 MW. Today there are 13 hydel power projects engaged in generating 5010 MW electricity. One gigantic project is under completion on Terbela Dam and one of its units began to generate eloctricity in since October, 2000 with a capacity of 290 MW. At the completion of this project, the total generating capacity of this project would be 1450 MW 290 each unit or there would be 5 units of this project.
Total hydel energy in Pakistan is under the control of WAPDA (Water and Power Development Authority). Out of 13 hydel power projects of Pakistan. 4 (Terbela, Mangla, Warsak and Chashma) are big while the remainder are small hydel power projects.
The detail of the 5 big projects is given below:

The concession period for the project is 35 years, including five years of construction period.
The total project cost is estimated to be $647.4m, which will be financed entirely by foreign capital.
The shareholders of NEWEDC include Korea South East Power Company (52%), Daelim Industrial Company (16%), Kyeryong Construction Industrial Company (10%), International Finance Corporation (12%), and the local Nepalese partner Mr. Bkesh Pradhanang (10%).
Construction on the project is expected to be started in 2020, while commissioning is expected in 2024.
The Upper Trishuli-1 project is expected to generate up to 1,456GWh of electricity a year and increase the country’s total power generation by 20%. It is expected to create employment opportunities for 500 local workers during the construction phase and up to 40 permanent jobs during the operation period.
Upper Trishuli-1 hydropower project make-up
The Upper Trishuli-1 hydropower facility will comprise a 100.5m-long, 30.9m-wide, and 30m-tall concrete gravity diversion dam structure approximately 275m downstream of the confluence of the Langtang Khola tributary with the Bhote Khosi River.
The diversion dam will create a 2.1ha impoundment, from where the water will be diverted through two horizontal bell-mouth type intake tunnel structures with 3.25m-wide and 6.5m-high roller gates.
Water will be discharged at a rate of 76m³/s, through a 9.7km-long and 6.5m-diameter low-pressure headrace tunnel.
Underground horizontal flushing type desander will be installed to settle and remove the sediments from water, while an 8.5m-diameter and 38m-long surge tank will be used to manage pressure changes in the headrace tunnel.
Water will flow through a 292m vertical pressure tunnel followed by a 40m-long horizontal pressure tunnel before entering the 110.7m-long and 1.6m-diameter steel-lined penstocks to drive turbines.
The underground powerhouse will be equipped with three vertical axis Francis turbine generator units of 72MW capacity each.
Water from the powerhouse will be returned to the Trishuli River approximately 10.7km downstream of the dam through three 6.5m-diameter and 55m-long tail-race tunnels, which will eventually combine into a 178m-long single concrete tunnel.
The Upper Trishuli-1 project site, located approximately 70km north-west of Nepal’s capital Kathmandu, can be accessed via a 15km access road on the right bank of the river.
Other infrastructure facilities for the project include operations and maintenance building, a switchyard, warehouse, administrative buildings, as well as accommodation buildings for workers.
Power off-take and transmission
Nepal Electricity Authority (NEA) will purchase the entire electricity output of Upper Trishuli-1, under a 30-year power purchase agreement (PPA) signed with NWEDC in January 2018.
The power generated by the plant will be evacuated to the national grid through a 1.1km-long 220kV transmission line connecting the Chilime-Trishuli transmission line.
The financing of the $647.4m project is planned to be met through 70% debt and 30% equity.
Equity investment of $194.2m will be provided by the project partners, while the debt of $453.2m is being provided by group of international lenders including International Finance Corporation, Asian Development Bank, Asian Infrastructure Investment Bank (AIIB), Proparco (France), DEG (Germany), FMO (The Netherlands), and Korean Development Bank.
Asian Infrastructure Investment Bank (AIIB) approved $90m loan for the Upper Trishuli-1 project in June 2019.
A joint venture of Daelim Industrial Company (60%) and Kyeryong Construction Industrial Company (40%) is the engineering, procurement, and construction (EPC) contractor for the Upper Trishuli-1 hydropower project.
Korea South East Power Company will be responsible for the operations and maintenance of the facility.


Major construction work has now started to restore Toddbrook Reservoir in Whaley Bridge, after the project’s 1970s-built spillway was damaged following torrential rain in summer 2019. The work is likely to cost around £15 million and take around two years to complete, with the reservoir due to reopen in late 2024.
The Canal & River Trust charity which cares for the reservoir and 2,000 miles of waterways across England and Wales, is working with its contractor Kier to deliver the restoration. Work has already begun to create a site compound on the northern end of the town’s Memorial Park, which has been temporarily closed to the public. Hoardings are being erected, site accesses installed and existing drainage and feeder channels realigned.
Later this autumn construction work begins to create a new overflow spillway structure to the north of the dam. This involves building a side channel weir, ‘tumble bay’, spillway channel and stilling basin which will link into the existing bypass channel flowing into the River Goyt in the park.
The final phase of the project will be to remove the concrete panels from the original overflow spillway. The dam will then be repaired and grassed over. This will be followed by works to the inlet cascade, at the far end of the reservoir, to increase resilience to high flows from Todd Brook stream.
“We are pleased to be starting work on the major construction project to restore Toddbrook Reservoir,” commented Tom Greenwood, project manager for the Canal & River Trust. “This comes after extensive investigation works, two independent reports, exploring multiple design options, two public consultations and a detailed planning application.”
