ERECTION OF THE TURBINE generating units at Kukuleganga hydro power project in Sri Lanka has commenced, in preparation for commissioning of the 70MW plant in late 2003.
Located about 90km south-east of Colombo, the plant harnesses the Kukule river, a main tributary of the Kalu river, second largest river in Sri Lanka. The run-of-river type Kukuleganga will be the second underground power plant in the Sri Lanka’s hydro dominated power system. The Japan Bank of International Cooperation is funding the estimated project cost of US$212M.
Key elements of the project are:
• 16m high 110m long concrete diversion weir equipped with four radial gates.
• 7.5km long 5.6m/6.4m diameter waterway system including a 220m deep, 7.5m/4.8m diameter vertical pressure and surge shaft.
• 52m x 16m x 32m underground cavern housing two 35MW turbine/generator units, along with the 8m x 9m x 31m transformer cavern for two 46 MVA transformers
• 27km long double circuit 132 kV overhead line connecting Kukule to the country’s national grid.
• Infrastructure facilities including two 9km long access roads providing access to the head and tail end of the project and residential camping facilities.
The whole project work is divided among eight contract lots and the main civil works of the project started in July 1999 followed subsequently by the other contract lots. Excavation of the tunnels were completed in March 2002 and the tunnel invert concreting and lining at identified sections are in progress. The most parts of the 5.7km long headrace and the 1.6m long tailrace tunnels will be left unlined as planned, taking the advantage of the excellent rock conditions prevailing in the project precincts.
Excavation of the two underground caverns and first stage concreting has been completed.
At the headworks end, construction works of the diversion weir under river diversion phase 1, which is about 70% completed. The balance works of the weir site will be completed under river diversion phase 2, which commenced in late August 2002. Under this phase, the river will be diverted over the completed part of the weir structure.
On completion of installations and erection works, the plant is scheduled for carrying out dry and wet tests towards the later part of next year, with expected full commercial operation by the end of 2003.
Once completed Kukule will add 317GWh of energy annually to the country’s power system, which has been faced with a serious power and energy shortage for several years.

The new power plant at Khodaafarin Dam will be jointly built by two neighbouring nations, agreed on Baku and Tehran, MehrNews reported.
Azerbaijan and Iran have signed an agreement, under which the two countries will build a hydroelectric power plant at the Khodaafarin Dam. The sides have discussed their disagreements over the financial calculations of the future dam power plant.
“One of the major projects that its executive operations started about 20 years ago was the Khodaafarin Dam on the Aras River border,” said Minister of Energy of Iran Reza Ardakanian on Wednesday.
For both Iran and Azerbaijan, the dam is important. The powerful object could also regulate about 1.6bn cubic meters of water annually. Minister Ardakanian added that the Khodaafarin Dam also will improve irrigation of the agricultural land. Two hydropower plants with a total capacity of 280 MW can generate electricity are able to improve the situation in both countries.
Commenting on the agreement signed between the government of Iran and Azerbaijan, the Iranian top official said that the financial calculations of the Khodaafarin Dam power plant are completed.
“Yesterday, we agreed with the Azerbaijan Deputy Prime Minister Shahin Mostafayev on this issue and we will immediately start building hydroelectric power plants at the Khodaafarin Dam,” Ardakanian said.


Direct Acting is the simpler of the two designs. It works by responding directly to changes in downstream pressure to maintain the necessary flow.
When the outlet pressure increases, the spring compresses and the plug closes to restrict fluid flow. This allows it to maintain the downstream pressure automatically
Materials: Ductile Iron/ Gunmetal/ Stainless Steel
Max Inlet Pressure: Up to 40 bar
Application: Air, Steam, Gases, Water, Oil & Liquids
The valve can be installed vertically or horizontally. It is recommended to have a downsection of at least 5 X pipe diameter. Pressure gauges can be also mounted as a option.
Pilot Operated Pressure Reducing Valve
The advantage of the pilot operated reducing valve is that the pressure sensing point can be placed further downstream for a more accurate pressure sensing. It is also more responsive to changes in pressure.
Pilot operated valve work by making use of the fluid medium to open and close the plug.

Urbanisation of a watershed with its associated impact on the quantity and quality of stormwater runoff has resulted in the implementation of a number of alternatives for storm-water management. The early stage of stormwater management initiatives in Malaysia is concentrated on the minimization of downstream flooding caused by urbanisation. The objective of the project is to implement the source control and distributed storage systems to resolve identified problems of flooding and hydraulic overloading using the infiltration engineering systems and storage tank system. This paper presents the concept and result for subsurface infiltration and storage tank system which are studied to control stormwater quantity in Engineering Campus Universiti Sains Malaysia, Tronoh, Perak. The purpose of this study is to attenuate the peak flood hydrograph and volume by using three different infiltration and storage techniques based on the surrounding soil conditions. These systems are module infiltration system, loose rock infiltration system and module storage tank system. This paper also discusses some results retrieved from automatic data acquisition system. The comparison of peak flow attenuation and volume attenuation for these infiltration engineering and storage tank systems are highlighted in this paper. The study shows that the peak flow attenuation rate varies with different rainfall magnitude and storm duration at three study locations. These characteristics are important for optimising the design of detention/retention facilities. Modification to the system has been carried out in stage II data acquisition period after encountering flow constraints from stage I data analysis. The simulation using XP-SWMM confirmed the results obtained from the experiment.

Lake Winnipeg Regulation
The Lake Winnipeg Regulation (LWR) project regulates flow out of Lake Winnipeg to help reduce shoreline flooding around the lake and to optimize power generation along the Nelson River.
The Province of Manitoba approved the project in 1970. We began construction in 1970 and it was in operation in 1976.
The project created a second outlet for Lake Winnipeg and a network of channels and structures. These control the outflow of water from the lake and increase the outflow potential by about 50%. The LWR outlet and channels reduce shoreline flooding on Lake Winnipeg in summer and provide more water to lower Nelson River generating stations during winter.
The LWR main components:
- The Jenpeg generating station and control structure – regulates Lake Winnipeg’s outflow through the west channel of the Nelson River.
- A series of diversion channels (Two-Mile Channel, Eight-Mile Channel, Ominawin Bypass, and Kisipachewuk Channel Improvement) – these increase the outflow capacity from Lake Winnipeg into the Nelson River.
For more information about the environmental effects, read the Regional Cumulative Effects Assessment.
Read more about the LWR Water Power Act licensing.


Update - October 2021
The channel and slope reconstruction will generally extend from the CN Rail embankment northerly to Oxford Street, along with a new culvert crossing Oxford Street to accommodate the upstream tributary areas that collect and flow into Mud Creek. The channel will be lowered and regraded to increase flow conveyance capacity within the channel. This project will be extensive with significant restorations, tree plantings, multiple habitat features and a recreational multiuse pathway. Construction is expected to be completed by the end of December 2022 with plantings to take place in Spring of 2023.

The basic structure of the centrifugal pump is composed of eight parts: impeller, pump body, pump cover, retaining ring, pump shaft, bearing, sealing ring, stuffing box.
1. The impeller is the core part of the centrifugal pump. It has a high rotational speed and high output force. The impeller on the impeller plays a major role. The impeller passes the static balance test before assembly. The inner and outer surfaces on the impeller are required to be smooth in order to reduce the friction loss of the water flow.
2. The pump body is also called the pump housing and it is the main body of the pump. It plays a supporting and fixing role, and is connected with the bracket that mounts the bearing.
3. The function of the pump shaft is to connect the coupling and the motor to transmit the torque of the motor to the impeller, so it is the main component of the transmission of mechanical energy.
4. The bearing is a member that is sleeved on the pump shaft to support the pump shaft. There are two kinds of rolling bearings and sliding bearings. The use of butter as a lubricant for rolling bearings should be appropriate. Generally, 2/3 to 3/4 of the volume will be too hot, too little noise and heat!
Sliding bearings use transparent oil as the lubricant and add to the oil level line. Too much oil has to leak along the pump shaft and drift away. Too few bearings have to be overheated and burned to cause an accident! In the process of running the pump, the temperature of the bearing is usually up to 85°C at a maximum of 85°C. If it is high, you must find out the reason (whether there is any impurity, whether the oil is black, whether it is in water) and handle it in time!
5, the sealing ring is also called the leakage reduction ring. The gap between the impeller inlet and the pump casing is too large. As a result, the water in the high-pressure area of the pump flows to the low-pressure area through this gap, affecting the pump output, and the efficiency is reduced! If the clearance is too small, it will cause friction between the impeller and the pump casing. In order to increase the return resistance to reduce the internal leakage and delay the service life of the impeller and the pump casing, a seal ring is installed at the inner edge of the pump casing and the impeller foreign aid joint, and the seal gap is preferably maintained between 0.25 and 1.10 mm.
6. The stuffing box is mainly composed of packing, water sealing ring, packing tube, packing gland and water sealing tube. The function of the stuffing box is mainly to close the gap between the pump casing and the pump shaft so that the water in the pump does not flow outside and the outside air does not enter the pump. Always keep the vacuum inside the pump! When the friction between the pump shaft and the filler generates heat, it is necessary to rely on the water seal tube to fill the water seal ring to allow the filler to cool! Keep the pump running properly. Therefore, the inspection of the stuffing box during the inspection tour of the pump is of special attention! The packing should be replaced after about 600 hours of operation.
7. Axial force balancing device During the operation of the centrifugal pump, the liquid enters the impeller under low pressure and flows out under high pressure, which causes the pressure on both sides of the impeller to be unequal, and generates axial thrust in the direction of the inlet. Axial turbulence of the rotor is caused, resulting in wear and vibration. Therefore, an axial thrust bearing should be provided in order to balance the axial force.


In-line check valve is mounted between the strainer and meter assembly to help increase air eliminator efficiency by creating additional back pressure and help reduce the reverse back flow.

Lake Wohlford Dam is an important water storage, flood control and recreational facility that has served Escondido for generations. Restoring storage capacity and making it earthquake-safe is critically important, which is why I introduced AB 692. The dam was originally constructed in 1895 to store water transported via a wooden flume from the San Luis Rey River to Escondido. One of the first rock-fill dams in California, Lake Wohlford Dam was 76 feet high and had a storage capacity of about 3500 acre-feet.

THE EXPRESS TRIBUNE, ISLAMABAD, 08th OCTOBER 2013: Tarbela Dam’s power generation capacity will increase to 4,888 megawatts (MW) with the completion of the fourth extension hydropower project, which will add 1,410MW to the existing capacity.
Official sources say that Tarbela will become the largest water reservoir in the country in terms of hydropower generation after the completion of the extension project, while Mangla will stay the largest water storage reservoir of the country.
The Water and Development Authority (Wapda) had already awarded civil works contract worth Rs26.053 billion to Chinese company, Sinohydro for the fourth extension project.
According to sources, the World Bank had also agreed to provide a loan of $840 million for the project. The extension project will take three and half years to complete at an estimated cost of $928 million.
After the installation of three units of 1,410MW, the generation capacity of the dam will touch 4,888MW.
On completion, the project will add 3.84 billion units per annum to the national grid. Annual benefits to be derived from the project had been estimated at Rs30.7 billion. The sources said that the project will pay back its cost in three years. The project will also be instrumental in saving foreign exchange on import of almost one million ton of furnace oil annually, required to generating equal amount of power from thermal sources.
The project will also provide a cushion to undertake rehabilitation and up-gradation of the existing Tarbela powerhouse after the completion of extension projects.
Tarbela fourth extension hydropower project is part of the government’s plan to focus on cheaper sources of power production, which is being implemented by Wapda on priority. This strategy aims at adding a sizeable amount of power to the system, while also improving the country’s energy mix.

CH2M was commissioned by the Environment Agency (England) to conduct a linked 1D-2D flood modelling exercise at Orton Meadows in Peterborough, England. The primary aim of the project was to provide clarity on the potential flood risk to residential properties.
The project involved the development of a 1D-2D model which included the River Nene, the Orton Dyke (one of its tributaries) and the lake system of Orton Meadows.
The model was developed using three different existing 1D models. These models showed the onset of flooding at Orton Meadows at different Annual Exceedance Probability (AEP) events (from 5% to 0.1% AEP).
A review of the three separate models was initially carried out using the ‘Health Check’ tool within Flood Modeller Pro, which ensured the existing modelling files were suitable for the proposed investigation.
Following the model audit, recommendations were made with regards to how to explicitly represent the potential flooding routes for Orton Meadows including the River Nene and Orton Dyke.
Due to the sensitivity of the water levels on the floodplain, the models were brought together in a single file and converted into a Flood Modeller-TUFLOW (1D-2D) linked model along the Nene and into the Orton Meadows area.
Efficiency savings in the model building stage were maximised by using the automatic Flood Modeller Pro 2D build toolset and its user-friendly mapping interface. The ability to implement operational rules and the geometry of the structures allowed the detailed representation of the complicated system of sluices, weirs and culverts between the river Nene and Orton Meadows.
Following the model build, CH2M carried out a sensitivity analysis on the effect of reverse flow at selected culvert outlets. This was extremely easy due to the explicit representation of the structures’ outlet in the software.
Once the model had been run, Flood Modeller Pro was used to extract depth/velocity grids and create animations for the depth layer. The automation tools available within the software were used to post-process model results in order to maximise potential efficiency, productivity and quality gains.
