MWY provided engineering design and construction management services in connection with a major upgrade of Springdale’s collection system in 1986. This included the construction of two lift stations, on Johnson and Robinson Lanes, and one million gallons of in-system flow equalization. The cost of the original facilities, including both stations, was $1,288,875.
In 2001, MWY performed a facility upgrade study for the existing Robinson Lane Lift Station, located on Robinson Lane in southwest Springdale.
The purpose of the study was to compare options for expanding the capacity of the facility while maintaining operation of the existing station. MWY later provided detailed plans and specifications for construction of the recommended improvements. Based on recommendations, the lift station was upgraded from a capacity of 3,600-GPM to a capacity of 6,500-GPM. The new station was designed for easy expansion to a capacity of 8,300 as needed.
The improvements included construction of an underground pipe gallery and a new wetwell with spaces for a total of five 185-HP submersible pumps (three immediate and two future pumps).
The improvements incorporated variable frequency drives that lower pumping rates during periods of low flow, which contributes to lower operating costs.

In this paper, details, and results of three-dimensional numerical modeling of flow around the semi-conical piers vertically mounted on the bed in a channel, are presented. For flow simulation, 3-D Navier-Stokes equations are solved numerically using the finite volume method and large eddy simulation (LES). In this study, the semi-conical piers with different side slope angles are tested, and the flow around them is compared with the cylindrical reference pier. Flow structures, vortex shedding behind piers, horseshoe vortices, instantaneous and time-averaged flow structures are presented and discussed. Numerical model results show that the semi-conical piers are eventuated remarkable reduction (up to 25%) in downward flow velocity in the upstream side of the piers, and much more reduction (up to 46%) in bed shear stresses in comparison with the cylindrical pier. Moreover, the model results showed some decrease in vortex shedding frequency for the semiconical piers compared to the cylindrical pier.


This study presents the rehabilitation project for the Francis turbine runner of Kepez 1 Hydroelectric Power Plant (HEPP) in Antalya, Turkey. The aim of rehabilitation is to increase the power and efficiency of the plant and solve the existing problems such as cavitation. Initially, the head and flow rate of the turbine are estimated. Within the scope of this study, the design parameters which are necessary to obtain better cavitation characteristics and higher power and efficiency, are determined and computational fluid dynamics (CFD) is utilized to design a new runner geometry for better performance. The results of the CFD simulations are compared to the simulation results of the existing runner geometry which was obtained from the plant and scanned using laser scanning. The results show that cavitation characteristics and the efficiency, as well as the power of the HEPP are improved.

Reservoir Operations Troubleshooting
Situation: On-channel reservoir will not fill to capacity.
- Check if there are sufficient storage rights (*.rer) to meet the reservoir capacity, as defined in the reservoir station (*.res) file.
- Review the reservoir target file (*.tar) to see if the monthly target equals the reservoir capacity set in reservoir structure (*.res) file.
- Check if the storage right is assigned to the correct accounts in the reservoir rights file (*.rer).
- Check if there is sufficient physically and legally available flow available to the reservoir.
- Review the River Balance information in the direct diversion summary output file (*.xdd), specifically reviewing River Inflow, Reach Gain, Available Flow, and Control Location at the reservoir.
- If the reservoir is located at the top of a tributary, make sure that natural flow has been distributed up to the reservoir.
- If there is physical flow but no available flow, there is a downstream calling right that is causing the reservoir to bypass the physical flow in the river to meet the downstream demand.
Situation: Diversion demand is not being fully satisfied from supplemental storage supplies.
- Check if reservoir account(s) specified as source(s) in the operating rule file (*.opr) has water in storage available for release; review reservoir contents for each account in the reservoir summary file (*.xre).
- If the release is via exchange, check if exchange potential is limiting the released amount. Review the River Balance information in the direct diversion summary output file (*.xdd) for each of the intervening structures.
- Check if the diversion demand capacity in the direct diversion station file (*.dds) is limiting additional releases from being diverted, particularly if the releases are being made via an operating rule with a carrier.
- Make sure the River Inflow to reservoir (River Inflow (+) column in *.xre file) is not equal to or greater
than the reservoir maximum release rate (
FloMax) assigned in the reservoir station (*.res) file, thus limiting releases due to downstream channel capacity.


In yesterday’s post I wrote about the Bulk River and Sand River that flows into the Elands River west of Port Elizabeth. The Sand River Dam is fairly close to the Elands River Road while the Bulk River Dam can just be glimpsed from the road. In the picture is the Bulk River with the dam barely visible higher up the valley.

The scheme involved the diversion of a section of the existing 1200mmᴓ 9B Trunk Sewer at Crag Avenue, Clondalkin Co. Dublin. The purpose of the scheme was to enable the site, currently traversed by the 9B sewer, to be developed as a Data Centre campus. The proposed diversion consisted of c.600m of new 1350mmᴓ pipework and 9 new manholes including two tie-in manholes constructed on the line of the existing 9B sewer at the upstream and downstream ends of the scheme.
Clifton Scannell Emerson Associates (CSEA) were appointed by Echelon Data Centres to assess route options, develop a Basis of Design Report in order to confirm project design parameters with Irish Water, develop a Detailed Design Report which outlines the geotechnical/earthworks design, hydraulic design of the pipeline, structural design of manholes and other structural elements and obtaining approval from Irish Water for materials used on the project. CSEA also acted as PSDP on the project and carried out site supervision.
The construction of the tie-in manholes involved the overpumping of the flows (c.300 litres/sec) in the existing 9B sewer during the works.

Condensate Centrifugal Pump What is an Extraction Pump?
An extraction pump is an important part of a feed water system.Generally, fitted in between the condenser and de-aerator, the extraction pump works as an excellent tool for generating the requisite pressure, to deliver the feed water from a condenser under vacuum to de-aerator or a feed pump inlet.
Extraction pump is usually a vertical shaft, two stage, centrifugal pump, which is used in applications involving high pressure and high volume. Centrifugal pumps are of the type, which due to their high capacity, require a specific minimum suction head to operate.
Almost all the feed systems having an extraction pump, use a condensate level controller system, which is attached to the condenser and perform two main functions:
- To maintain the amount of condensate in the condenser
- To provide the sufficient suction head to the extraction pump
Construction & Working
A centrifugal pump, consists of three main parts – impeller, diffuser and volute casing.
A two stage centrifugal pump consists of two impellers arranged as shown in the figure. The high temperature water, which is almost boiling due to the low vacuum condition, enters the first stage impeller from the suction line. The high temperature water receives slight positive pressure from the first stage impeller and it then passes through the second stage impeller. In the second stage impeller, water gets more pressurized, almost equal to the required system pressure. The pressurized water then passes through the diffuser, where the strategically arranged vanes pushes the water towards the volute casing at an even higher pressure. The volute casing removes the water through the water outlet at the appropriate system pressure.
The feed systems in which the condenser sump level is of a fluctuating type or where there are chances of the pump running dry, a self-regulating type of extraction pump is used. A self-regulating type of extraction pump aligns its required suction head according to the condensate level in the condenser. But this type of extraction pump often faces the problem of cavitation, which occurs when the suction head falls to a very low level. Cavitation is a phenomena in which the vapour bubbles inside the pump collapse, resulting in the reduction of pump discharge rate to almost zero. The cavitation will only go when the pump suction head again increases, which will help in getting rid of the vapour bubbles trapped inside the pump. Once the suction head increases, the pump begins to discharge again.
Cavitation can also lead to the damage of the internal parts of the pump, but this occurs at high pressure. At low pressure conditions, the pump would not be affected. The biggest damage due to cavitation occurs to the impeller of the pump.Nowadays the impellers are designed in such a way that the air bubbles, even if gets produced, collapse away from the impeller.

Capacity of a pump is the fundamental data used in selecting certain pump. The flowing speed of the pump is very useful to determine the pumps capacity for irrigating process. This capacity must fulfill utilizing requirements which focus on two main criteria : 1) total capacity of pumps must provide maximum necessity (necessity on the highest point), 2) those pumps must be able to work efficiently and continously in the fluctuating condition. In order to fulfill the two criteria above it is necessary to use two ore more pumps with same capacity.

The development of a comprehensive ORCC/Morganza Delft3D numerical model will enable assessment of hydrodynamic and sedimentation processes. This effort will build on the modeling effort recently conducted by ERDC which included ADH and CH3D model studies. This 3D model will be used to assess project effectiveness and future sustainability, especially in terms of sedimentation in the channels of the ORCC. The need for physical models, non-hydrostatic model investigations and additional 3D CFD models to evaluate structure performance and structural means that would need to be performed to reduce risk of low sill structure failure will be assessed. Model studies will include assessment of the river and channels under various operational schemes, and evaluation of effectiveness of structural and operational alternatives.
Such a model will allow studies including
- Depth averaged hydrodynamic only studies of the operational impacts between the various structures
- Operation of the Overbank Structure and investigation of the staggered panel configuration would be investigated, i.e., what are the effects of staggered panel prior to flood, if no operation is needed?
- 3D sigma stretched hydrodynamic studies

LAHORE - The raised-Mangla Dam became the biggest water reservoir in the country as water storage in its lake increased to 6.65 million acre feet (MAF) on Sunday morning.
The water level surpassed 6.58MAF benchmark, which was the maximum live storage capacity of Tarbela Dam that used to be the biggest water reservoir till August 24, 2013, said the Wapda spokesperson.
“Consequent upon the successful completion of the Mangla Dam Raising Project, it has become the largest water storage facility in the country. With increase in dam’s height by 30 feet, now water could be stored in the reservoir up to 1242 feet against the previous conservation level of 1202 feet above mean sea level. Resultantly, the live storage capacity of the raised Mangla Dam has increased to 7.39 MAF from 4.51 MAF. Given the current weather forecast, the prospects for filling of Mangla reservoir to its maximum conservation level are bright. If the raised Mangla Dam is filled to its maximum conservation level i.e. 1242 feet, 2.88 MAF of additional water will be available for the agriculture and generation of low-cost hydel electricity in the country.”
The Mangla lake has crossed 1232.5 feet level, meaning thereby, 2.14 MAF additional water is available in the reservoir. In addition to managing the current floods, benefits worth billions of rupees in agriculture and power sector will also be accrued through utilisation of this additional water.
The Wapda spokesperson added: “Last month, it was mutually decided by all stake holders to fill the raised Mangla Dam this year up to its maximum level, as the Federal Government had promised to pay off the financial liabilities of the project affectees for the purpose.”

SAULT STE. MARIE, MI-- President Trump’s 2020 budget request includes $75.3 million to construct a new Soo Lock.
The funding would be used to initiate construction of the upstream approach walls, continue the design of the lock chamber and complete construction of the upstream channel deepening.
Only one lock—the Poe—is large enough to handle the biggest freighters on the Great Lakes. Officials say the Soo Locks are critical to U.S. manufacturing and national security, and a breakdown of the Poe lock would compromise both.

The dam will be built on Panjshir and Ghorband rivers with the capacity to generate 250 megawatts of electricity.
The construction of the Bagh Dara dam will take around five years.
Sayed Massoud, an economic affairs experts told Ariana News that construction of the dam will decrease Afghanistan’s dependability to the imported electricity.
He added that it will create employment opportunities and will help to the security and growth of Afghanistan.
Currently, 73 percent of Afghanistan’s power supply is imported from its neighboring countries including Tajikistan and Uzbekistan.
Earlier, India built Salma Dam in western Herat province of Afghanistan with $290 million.


“TRNC Water Supply Project”, which is being called “the project of the century”, will become operational on 7th August as the last component gets added. As part of the project, the water pipe constructed under the sea, which is currently 66.5 kilometres long, runs from the Alaköprü dam in Mersin to Northern Cyprus.
According to the information obtained by Anadolu Agency reporters, due to completion of the water pipeline, there will be a ceremony on Friday, 7 August in the TRNC with the participation of the Turkish Minister of Forestry and Water Affairs Veysel Eroğlu.
As part of the project, which is intended to be finished by the end of this year, the construction of a 24-km-long transmission line from the Turkish side, a 3.7-km-long transmission line from the Turkish Cypriot side, and a 67-km-long transmission line from the Geçitköy water supply station has been completed.
The construction of transmission lines from the TRNC water treatment plant to Kyrenia, Famagusta and Dipkarpaz is still ongoing.
When the project terminates, 75,000,000 cubic meter (cbm) of drinking and irrigation water will be supplied from the Alaköprü dam to the Geçitköy dam in the TRNC annually through a 106-km-long pipeline. There will be a 23-km-long pipeline in the Turkish side, an 80-km-long pipeline under the sea, and a 3-km-long pipeline in the TRNC.
38 million cbm water from the dam’s reservoir will be used for drinking, and 37 million cbm water will be used for irrigation.
The project will be able to compensate for the TRNC’s projected water need for the next 50 years, and especially the irrigation water will raise the agricultural revenue of the country.

The construction works of five large new dams will be launched in 2021, for an overall budget of DH 4.8 billion and a capacity of 525 million m3, said Tuesday in Rabat minister of Equipment, Transport, Logistics and Water, Abdelkader Amara.
These dams will be constructed in Oued Lakhdar (province of Azilal), Taghzirt (province of Béni-Mellal), Tamri (prefecture of Agadir Ida-Outanane) and Alkhankro (Figuig), in addition to the Imfout dam, in Settat, which will be enlarged, Amara said at the House of Advisors (upper house) at a session dedicated to the national water strategy (2009-2020).
According to the minister, these projects are part of the national drinking water supply and irrigation program for the period 2020-2027, which seeks to increase the total capacity of dams to 27 billion m3 at the end of the construction works.
During the period 2009-2020, 23 large dams were launched, for an overall cost of DH 28.2 billion, which would increase the capacity to 6.237 billion m3, he said, adding that seven dams are already operational while 11 others are under construction.
The construction of five large dams were launched in 2020 for a total cost of DH 7.8 million, with a capacity of 2,237 million m3, Amara pointed out.
Regarding the national water strategy, in particular the section relating to the 60 planned dams, including those which were under construction in 2009, Amara said that 26 dams have been built or are under construction.
Thanks to the proactive water policy, initiated in accordance with the enlightened royal vision of late HM Hassan II and which was consolidated by HM King Mohammed VI, Morocco has acquired an important water infrastructure, he underlined, adding that there are 149 large dams with a total capacity of over 19 billion m3 in addition to 133 small dams.


Melbourne Water will soon upgrade the Upper Yarra Reservoir dam.
It said the project was an important initiative for residents of Warburton, Reefton, McMahons Creek and the Melbourne metropolitan area, as it would ensure the dam wall’s continued integrity and stability.
Melbourne Water said the reservoir could then continue to supply drinking water for Melburnians.
The dam is about 5 kilometres east of Reefton, is an important link between the Thomson Reservoir and the water supply network, and was built in 1957.
“Melbourne Water regularly reviews the risk associated with its water supply dams,” a statement said.
“Understanding the risk allows us to prioritise maintenance and upgrade works as necessary.
“We apply the best Australian and international engineering practices in the design, management and operation of dams.
“This upgrade is an important project to ensure Upper Yarra Dam continues to operate at its best.
“This dam safety upgrade will apply current engineering practice, to provide for the safe ongoing operation of the dam.”
Minor works are due to start in March and full construction works will start from June.
Melbourne Water expects the works to be completed over two summer phases, by mid-2021.
“The project will install a sand filter on the downstream side of the embankment crest for its full length,” the statement said.
“This acts to protect the clay core of the embankment from erosion, and will also allow any seepage through the embankment to be monitored.”
The upgrade will involve excavating a trench along the crest of the wall; backfilling the trench with a new sand filter; fencing off and closure of the works area.
The project will close the Upper Yarra Reservoir Park from June until mid-2021, bring heavy vehicle truck movements along the Warburton Highway, and include improvements to the amenities within the campground.
“Some vegetation removal will be required to complete the works,” the statement said.
“Vegetation removal will be undertaken with the supervision of a qualified arborist and wildlife handler and in accordance with statutory requirements.”


Knox Vision Society
District of Sooke
Located at the corner of Church Road and Wadams Way in the District of Sooke, Westbrook Consulting provided civil engineering design and construction services for the construction of a new affordable living apartment facility by the Knox Vision Society.
Westbrook provided preliminary design concepts, detailed design of the development, construction inspection services, construction survey layout, and assisted the developer and architect with various municipal approvals and contract management.
A challenge of the project was the initial uncertainty of the capacity of the existing storm drain system. Onsite detention was utilized to in order to limit the runoff from the site to that of pre-development conditions, thus eliminating the need for upgrades to the downstream system.
Another project challenge was the desire for the existing Knox Church to remain on the site. New water works and BC Hydro infrastructure had to be designed in such a manner that they could be constructed in close proximity to the existing building.
Detailed design was completed in late 2017 and the project is currently under construction.

The Lower Subansiri hydroelectric project being built on the Subansiri River, a tributary of the Brahmaputra River, on the border of Assam and Arunachal Pradesh will be one of the biggest hydroelectric facilities in India.
The construction of the mega hydropower project has been underway since 2005.The 2GW hydropower station is being developed by India’s state-run National Hydro Power Corporation (NHPC) with an estimated investment of £2.21bn (Rs203.7bn).
Scheduled for commissioning in August 2023, the Lower Subansiri hydroelectric power station, intended for base-load operations, will generate up to 7.4 billion kWh of electricity annually.
Location and site details
The project is located near North Lakhimpur, in the Lower Subansiri district of Arunachal Pradesh, in the north eastern part of India.
The project site is approachable from the Nagaon railway station and the Lilabari/Dibrugarh airport.
Lower Subansiri hydroelectric plant make-up
The Lower Subansiri hydroelectric project includes the construction of a surface powerhouse and a concrete gravity dam which will be 116m-high from the river bed level.
The powerhouse will comprise eight Francis-type turbines capable of generating 250MW of electricity each. It also comprises a control block and a transformer hall.
Eight horseshoe-shaped head race tunnels of 9.5m-diametre will be built to carry water from dam to the powerhouse. The length of the head race tunnels will vary from 608m to 1.1km.
The project also includes the construction of eight 9.5m-diametre horseshoe-shaped surge tunnels with length varying from 400m to 485m.
There will be eight vertical circular pressure shafts with varying length from 195m to 215m. The shafts will be installed vertically at a depth of 48m.
The tail race channel of the power station will measure 206m in width and 35m in length.
ÅF Pöyry (AFRY), a Swedish engineering, consulting and design company, was contracted for setting up the management information system (MIS) for the construction management support, in addition to providing the design review services for the temporary structures, the basic design and planning services for the river diversion, as well as the geotechnical and claims preparation services for the project.
Larsen & Toubro (L&T) was awarded the engineering, procurement and construction (EPC) contract for the civil and structural works pertaining to the water intake structure, head race tunnels, surge chamber, pressure shaft, powerhouse and the tail pool in January 2004.
L&T, however, was released from the project work in 2015 while Patel Engineering was awarded a £160m (Rs15.6bn) contract to complete the remaining civil works in October 2020.
Alstom (now GE) was awarded the turbine supply contract in April 2005 while Texmaco was contracted for the supply of the hydro-mechanical package for the project in June 2006.
Subansiri Lower hydroelectric project background
Although the construction works were started in 2005 with completion expected in 2010, the project development was stopped in 2011 due to stiff resistance over the alleged adverse environmental impact of the project.
The development activities were restarted following the execution of an memorandum of agreement (MOA) between the Government of Assam and NHPC in August 2019.
NHPC previously signed an MOA with the Government of Arunachal Pradesh in January 2010.

Polihali dam will be a CFRD, similar to the Mohale dam, which was built during Phase I of the Lesotho Highlands Water Project (LHWP). The embankment will be approximately 166 m high, have a crest length of about 920 m and a crest width of 9 m. More than 14 x 106m3 of rock which will be quarried locally within the dam basin will be compacted to form the dam. It will create a reservoir on the Senqu and Khubelu rivers with an estimated surface area of 5053 ha and a full supply storage capacity of 2325 x 106m3. The Polihali dam infrastructure also includes a 43 m-high, a CFRD saddle dam with a crest length of 600 m, a spillway and a compensation outlet.
The flow from Polihali will increase the volume of water to be transferred from the Katse dam, the centre point of the LHWP which was constructed during Phase I. The current water transfer volumes to the Gauteng region of South Africa will incrementally increase from 780 to 1270 x 106m3/year. This will also simultaneously increase the energy generated by the ‘Muela hydropower plant from approximately 500 GWh to 800 GWh/year, a further step in the process of securing an independent power supply to meet Lesotho’s domestic needs.
“The launching of the construction of the main works open tender is the culmination of years of planning and hard work of dedicated design and procurement teams. Our objective with this final procurement stage is to attract suitably qualified companies with the capability, experience and resources to undertake the construction of the Polihali dam within the set timeframes and to the required quality,” said Tente Tente, CE of the LHDA.
The Phase II Agreement encourages the project to benefit the economies of Lesotho and South Africa but emphasizes the need for procurement that fosters competitiveness, transparency, cost-effectiveness and quality. LHDA’s robust procurement policy and tender evaluation protocols will ensure a fair and transparent procurement process.
The Matla a Metsi Joint Venture which comprises Lesotho, South African and international experts: GIBB (Pty) Ltd; MPAMOT Africa (Pty) Ltd; Tractebel Engineering SA; LYMA Consulting Engineers of Lesotho, was awarded the Polihali Dam design and construction supervision contract in 2017.
The Polihali dam construction procurement is launched as construction activity on ten advance infrastructure contracts progresses steadily with some contracts expected to be completed this year. Construction of the 33 kV line, which will provide a temporary power supply to the Polihali village, was completed last year. Work on the 132 kV line has advanced with the construction of access roads, 91 tower foundations and the erection of 84 towers of a total of 93. The Polihali and Katse civil works, access roads, pipe laying for potable water and sewerage lines have been completed, and construction on the main access roads is underway. Excavation on the Polihali diversion tunnels is close to completion, with breakthrough on both tunnels expected in the second half of August.
According to the current master programme, water delivery is scheduled for 2027/28. The construction schedule for the dam and transfer tunnel is critical to meeting the water delivery deadline of the project.
The launching of the dam construction tender process marks the start of the final construction phase of the water transfer component under Phase II of the Lesotho Highlands Water Project.
Interested construction firms have until 12 November 2021, to submit tenders.
Specific information on the requirements and conditions of the tender is available on the LHDA website at: www.lhda.org.ls/tenderbulletin/currentProcurement.aspx.


The construction of Kaw Lake and Dam was authorized by the Flood Control Act of October 24, 1962. Ground-breaking ceremonies for Kaw Lake and Dam were held on May 21, 1966, and the project was dedicated on May 22, 1976.
Kaw Lake and Dam are operated by the U.S. Army Corps of Engineers
. The lake's surface area is approximately 38,000 acres at the top of the flood control pool. The top of the flood control pool is 1,044.5", while the normal operating level is 1,010". Kaw Dam is 9,466" long and 121" above the stream bed. It is 654 miles above the mouth of the Arkansas River.
The total cost of Kaw Lake and Dam was $111 million, including the construction of a foundation for a power house, tailrace guard, and penstock in the dam. The Oklahoma Municipal Power Authority
purchased the substructure from the U.S. Army Corps of Engineers for $3.8 million in July of 1987. Construction began on August 29, 1987 and was completed in September 1989. The hydroelectric plant was declared commercial on September 26, 1989.
Operation of the Kaw Hydroelectric Plant is monitored via the Supervisory Control and Data Acquisition (SCADA) system at the OMPA office in Edmond, Oklahoma, which the Ponca City Utility Authority uses as back-up during off-hours. Operating as a run-of-river facility with daily ponding, Kaw Hydroelectric generates approximately 104 gigawatt hours of energy for the OMPA power supply system on an annual basis. The generator is nominally rated at 25.6 megawatts at 76" of gross head with a maximum rating of 36.7 MVA. The plant was constructed at a total cost of approximately $25 million.

LISFLOOD-FP model in which channel flows are resolved separately from the floodplain flows using either a kinematic or diffusive wave approximation has been used to analyze flooding behavior on the lower Mankyung River influenced by backwater. A calibration and validation process was applied using the previous flood events to assess the model performance. Sensitivity analysis was conducted for main calibrated parameters, such as Manning roughness coefficient and downstream boundary condition. Also, we examined the effect of warm-up for the initial conditions. The results show that the computed hydrograph is in good agreement with measured data on the study reach, even though it was a hydrologic kinematic wave model. The sensitive analysis show that the difference between the computed results may be greater depending on the used calibrated parameters and that the sufficient calibration/validation process against various flood events is necessary. If the flood inundation simulation is performed using the validated model, it is expected to be able to contribute about river planning and policy decision-making for flood damage reduction.

What is Impulse Turbine?
Impulse turbine is a type of turbine that works based on the principle of impulse, converting the energy of flowing water, steam, or gas into mechanical energy. It uses the force of the fluid’s high velocity impacting the turbine blades, causing them to rotate.
Examples of Impulse Turbine
Some examples of impulse turbines include:
1. Pelton Wheel: Used for high head applications, such as in hydroelectric power plants.
2. Turgo Turbine: Utilized for medium head applications.
3. Tangential Flow Turbine: Used in applications where both low head and high flow rates are needed.
Uses of Impulse Turbine
Impulse turbines find their applications in various industries, such as:
1. Hydroelectric Power Plants: Harnessing the energy of flowing water to generate electricity.
2. Steam Turbines: Converting high-velocity steam into rotational energy to drive generators in power plants.
3. Gas Turbines: Utilizing the flow of hot gases to produce mechanical power.
What is Reaction Turbine?
Reaction turbine is another type of turbine that functions by reacting to the pressure exerted by a fluid, such as water or steam. Unlike impulse turbines, reaction turbines operate using the principle of both impulse and reaction forces.
Examples of Reaction Turbine
Some examples of reaction turbines include:
1. Francis Turbine: Widely used in hydroelectric power plants, especially with medium head and flow conditions.
2. Kaplan Turbine: Suitable for low head and high flow rate conditions, commonly employed in river and tidal power plants.
3. Propeller Turbine: Used in applications with low head and high flow rates, such as in irrigation systems and drainage pumping stations.
Uses of Reaction Turbine
Reaction turbines find their applications in various industries, including:
1. Hydroelectric Power Plants: Converting the energy of flowing water into mechanical energy to generate electricity.
2. Steam Power Plants: Transforming high-pressure steam into rotational energy.
3. Ship Propulsion: Propelling ships and submarines using the flow of water around the turbine blades.
Differences between Impulse and Reaction Turbine
|Operates solely on the principle of impulse.
|Functions based on both impulse and reaction forces.
|The fluid impacts the blades and changes direction without any pressure change.
|The fluid reacts to the blades, causing a pressure change and continuous flow.
|Blades not shaped to alter fluid pressure.
|Blade shape designed to increase or decrease fluid pressure for better efficiency.
|Impulse turbines generally have higher efficiencies.
|Reaction turbines offer higher efficiencies with changing head conditions.
|More suitable for high head and low flow conditions.
|Well-suited for medium to low head and high flow conditions.
|The fluid velocity remains constant throughout the turbine.
|The fluid velocity decreases along the turbine’s length.
|Number of Stages
|Impulse turbines are single-stage turbines.
|Reaction turbines can be single or multistage turbines.
|Impulse turbines rotate at higher speeds.
|Reaction turbines rotate at lower speeds due to the pressure difference.
|Impulse turbines have simpler control mechanisms.
|Reaction turbines require complex control mechanisms.
|Impulse turbines are generally less expensive.
|Reaction turbines can be more expensive due to their design complexity.
In summary, impulse and reaction turbines differ in several aspects. Impulse turbines operate solely on the principle of impulse, while reaction turbines combine both impulse and reaction forces. The blade design, efficiency, operating capabilities, and cost vary between the two types of turbines. Selecting the appropriate turbine for a specific application depends on factors such as head conditions, flow rates, and desired operational efficiency.

Open channels are one of the most used water conveyance systems to deliver water for diﬀerent purposes. Existing models for the design of open channels mainly assume uniform ﬂow, focus on cross-section sizing, and generally decouple cross-section sizing from the selection of channel alignment and proﬁle. This study developed an optimization model for a comprehensive design of conveyance channels. The model minimizes the sum of costs for earthwork, lining, water losses, and land acquisition; accounts for non-uniform, mixed-regime ﬂow; and considers multiple geometric and hydraulic constraints. The model was validated using several idealized scenarios. The model potential in minimizing the cost of real open channel projects was demonstrated through application to an existing irrigation water transmission canal in Egypt (the Sheikh Zayed Canal). The results of validation scenarios matched the anticipated outcomes for channel proﬁle and alignment and reproduced analytical solutions given in the literature for channel cross-section design. Application of the model to the Sheikh Zayed Canal gave a more optimal design; the OCCD model produced a design alternative with ~27% less cost than the constructed alternative.


The proposed Koel-Karo project was first proposed in 1957 under the second Five Year Plan. The final project report was completed in 1973, and initially the total cost was estimated to be Rs 137 crore. According to the project report, two dams were to be constructed — at Basia on the South Koel River and at Lohajimi on the North Karo River. The two dams were to be connected by a 34.7km canal. To facilitate power generation, permission was given for the construction of four large power houses and two smaller ones, capable of generating 710MW daily. The project, covering Ranchi, Gumla and Singhbhum districts, was to utilise water from South Koel and North Karo rivers. The project became a non-starter following opposition from tribals who feared large-scale social and cultural displacement. The project was formally shelved in 2003 following intense protests by the local population.

The DAYLIFF DSP range of submersible multistage centrifugal pumps are specially designed for borehole supply applications. Material of construction include noryl impellers, glass filled polycarbonate diffusers, stainless steel inlet and outlet chambers, stage casings, shaft and pump housing. These quality materials together with the floating type impeller design provide the pumps with efficient performance ,excellent sand handling capabilities and long life.
The pump is coupled to a two pole sealed motor constructed principally from stainless steel. Single phase motors are supplied with a separate control unit that incorporates an isolator, run indicator light, thermal overload protection and starting capacitor which can be connected directly to the mains power. The box is also provided with auxiliary terminals for control probes, pressure switch or float switch. Three phase motors require a remote DOL starter; a DAYLIFF electronic pump controller is recommended for comprehensive pump control including wireless low level protection, motor overload and voltage fluctuation.
Enclosure Class: IP68
Insulation Class: F
Pumped liquid: Thin, clean, chemically non aggressive liquids with a max. sand content of 50g/m³.
Max. Water temperature: +35°C
Max. immersion depth: 200m
Min. borehole diameter: 110mm


Centrifugal pumps should be selected and normally operated at or near the manufacturer’s design rated conditions of head and flow. This is usually at the best efficiency point (BEP).
Pump impeller vane angles and the size and shape of the internal liquid flow passages are fixed and can only be designed for one point of optimum operation. For any other flow conditions, these angles and liquid channels are either too large or too small.
Any pump operated at excess capacity - i.e., at a flow significantly greater than BEP and at a lower head - will surge and vibrate, creating potential bearing and shaft seal problems as well as requiring excessive power.
When operation is at reduced capacity - i.e., at a flow significantly less than BEP - and at a higher head, the fixed vane angles will now cause eddy flows within the impeller, casing and between the wear rings. The radial thrust on the rotor will increase, causing higher shaft stresses, increased shaft deflection, and potential bearing and mechanical seal problems, while radial vibration and shaft axial movement will also increase. Continued operation in this mode will result in the accelerated deterioration of the mechanical and hydraulic performance and may ultimately result in the failure of the pump.
