Water reservoirs serve such essential purposes as water supply, irrigation, and hydroelectric power developments. Their effective and safe operations need reliable hydraulic structures for flow control. Siphon spillways are a flow control structure, with two main advantages: 1) no moving parts required and thus less susceptible to breakdown; 2) the ability to pass full discharge with a minimal increase of reservoir water level. The second advantage makes it easier to maintain target water levels as water resources while to ensure safe operations. The design of a siphon spillway uses one discharge head only, termed the design head, which is derived from statistical analysis of hydrological data for the reservoir region. However, under climate change, most existing siphons have been or are expected to be subject to actual discharge heads larger than their design heads. In other words, climate change results in submerged exit condition for siphon flow.
Previous studies of siphons focus on their hydraulic performance under free discharge condition. How submergence affects the flow is a question, not addressed previously. The flow over the crest of a siphon is highly curved. It is a challenge to deal with the curved boundary surface of the crest in siphon analysis. Streamline curvatures, three-dimensional vorticities and other subtle characteristics of the velocity and pressure fields remain to be discovered. Existing studies limit to a qualitative description of siphon flow and oversimplify flow mechanisms. The purpose of this research is to improve our understanding of siphon flow characteristics in a range of submerged exit conditions; to reveal any changes in the hydraulic performance of siphons, compared to free discharge conditions; and ultimately to contribute to an improved design of siphons.
This research took the approach of combining laboratory experiments with mathematical modelling. The experiments used a scaled model siphon. It was fabricated and tested in the Hydraulics Laboratory at Concordia University. A series of experiments were conducted to determine the discharge coefficient in a range of flow rates. A three-dimensional computational fluid dynamics (CFD) model was established for predicting the velocity and pressure fields as well as turbulence quantities. The CFD model used mesh refinement for regions close to solid boundaries and computed two-phase flow. The free surface of reservoir was tracked using the volume-of-fluid (VOF) method. Turbulence closure was obtained using the RNG k‐ε model.
The CFD model predicted detailed distributions of the flow field, including curvilinear flow features in the crest region. The flow characteristics corresponded to various conditions of submergence at the downstream exit of the siphon conduit, and included primary flow velocity, secondary flow velocity, turbulence kinetic energy, and pressure. The predicted discharge coefficient compared well with experimental data. The predicted mean-flow velocities were validated using estimates from the potential flow theory.
The experimental and computational results lead to the following findings: 1) The flow in the upstream reservoir is relatively uniform, with smooth movement toward the siphon entrance. At the entrance, the flow contracts, causing the pressure to drop below the hydrostatic pressure level in the upper corner of the entrance. Under the impact of centrifugal forces, the flow at the crest is forced to move in the extrados direction, causing secondary flow and an increased velocity above the crest. 2) The velocity rapidly increases near the crest and reaches the maximum at a very small height from the crest surface. In the zone above the boundary layer, the velocity decreases gradually before it starts to rapidly decrease near the crown surface. 3) Flow separation occurs just a short distance downstream of the crest. Eddies start to form on the crest and develop along the lower leg of the siphon. Further downstream, the flow contracts by a deflector, creating flow separation on the downstream side. 4) The pressures differ along the siphon conduit, with negative values in the crest region. The pressure decrease is proportional to the increase of velocity. Negative pressures at the crest surface may drop to water vapour pressure at the prototype scale. 5) The discharge coefficient is a parameter of practical importance. It allows one-to-one determination of siphon discharge from the head which is simple to measure. Values of the discharge coefficient range from 0.62 to 0.67 under submerged exit conditions. These values are larger than those under free discharge conditions.
This study has contributed to a better understanding of flow behaviours in a region bounded by curved boundaries. The CFD modelling strategies discussed in this research can be applied to analyse complex flows in similar hydraulic structures. The pressure data reported can possibly be used to access risks of cavitation in siphon spillways. In conclusion, the siphon flow is a complex flow, with curvatures, three dimensionality and turbulence. Through laboratory experiments and mathematical modelling, this research sheds lights on the flow characteristics such as discharge performance, velocity distribution, and pressure distribution.

Generation change in the Classic model series
As of 1st September 2016, both the low water and high water level limiters as well as the capacitive level control is to be replaced by the successor generation. The production of the older versions will therefore be stopped entirely.
Attention: The products SMLC1, LMC1 and SMHC1 as well as EC6 and DLT1 have therefore limited availability.
In the field of water level limiting all the new generation evaluators, communicate with the existing level electrodes. Thus, replacement of the electrode itself is not required. Only in the field of capacitive level control the evaluator and electrode have to be replaced due to conceptual reasons.
Water level limiter
Low water level limiter: SMLC1 → SMHC2
High water level limiter: SMHC1 → SMHC2
The low water level limiter with simple design LMC1 (no self-monitoring) will, in future be available as LMC2.
Capacitive Level Controller
Capacitive level controller: DLT1 → DLT2
Capacitive level electrode: EC6 → EC8
EC8 and DLT2 correspond to the pressure equipment directive 2014/68/EU.
Datasheets, PED certificates and SIL certificates can be downloaded on our webpage.
Prices and further information are available on request. Please address your respective salesperson.

The Sankh River originates from Rajadera village of Gumla district. It is one of the three main rivers flowing through the district. After traveling through Gumla, it enters Simdega Districtand flows towards Orissa.
The river joins with the Brahmani River at Vedvyas near Rourkela. Mandira Dam is situated across the Sankh River, where boating facility is available. The length of the river is 240 Km. The 60 metres (200 ft) high Sadni Falls on the Sankh River at the edge of the Ranchi plateau is an example of scarp falls or knick line falls.


SPR – Single Separator:
SPR model hydrocyclones are static type separators that remove solids from liquids through a centrifugal effect. The incoming dirty fluid gains a circular motion as it passes between the fixed helical blades inside the body. The resulting centrifugal force causes solid particles in the liquid to be thrown outward. These separated particles are discharged from the bottom of the separator.
These models can be used individually or in battery configurations.
Designed for high flow rates, multiple SPR model separators are installed in the same body. This allows achieving flow rates of around 3000 m³/h with a single unit.

Ukrhydroenergo says that the engine room of the Kakhovka hydroelectric power plant was blown up from the inside, rendering the whole plant irreparably destroyed.
The reservoir is estimated to be releasing water during the next four days.
"The uncontrolled fall of the water level in the reservoir is an additional threat to the temporarily occupied Zaporizhzhia NPP. Water from the Kakhovka reservoir is necessary for the plant to power its turbine capacitors and safety systems. The plant’s cooling pond is currently full. The Ukrainian staff at the ZNPP is monitoring all indicators," the company said.
As of 9:00 a.m., June 6, the water level in the kakhovka reservoir is rapidly falling, and the evacuation of people from the potentially flooded areas has begun.

Hawk Measurement Sultan Acoustic Wave Level
Principle of Operation
Hawk Measurement Sultan Acoustic Wave Level uses the transmission of high powered acoustic waves ensures minimal losses through the environment where the sensor is located. Due to the high powered emitted pulse, any losses have far less effect than would be experienced by traditional ultrasonic devices. More energy is transmitted hence more energy is returned. Advanced receiver circuitry is designed to identify and monitor low level return signals even when noise levels are high. The measured signal is temperature compensated to provide maximum accuracy to the outputs and display.

Theoretical and empirical burst pressure prediction models are developed.
The models quantify effect of defect geometry and orientation on burst pressure.
Burst pressure experiments are used to validate the model predictions.
Axial defect is more detrimental to burst pressure than circumferential defect.
Accurate prediction of the burst pressure is essential for structural integrity assessment of pipelines. Current design codes and models for residual burst pressure assessment of pipelines with surface corrosion defects are only applicable to axially orientated defects. Theoretical and empirical models for the prediction of burst pressure of thin-walled pipes with pre-existing localised and arbitrarily oriented surface corrosion defect are proposed. The theoretical model is based on power-law hardening and J2 flow theory while the empirical model is derived from nonlinear finite element analysis results of the burst pressure. Burst pressure experiments are used to validate the model predictions. The theoretical and empirical models are found to be reliable in predicting the effect of defect width, length, and orientation on the burst pressure.


La Crosse, Wis. based marine construction firm J.F. Brennan Co. Inc. has secured a contract from the U.S. Army Corps of Engineers for work at the Brandon Road Lock and Dam in Rockdale, Ill.
The company was the sole bidder for the $23,484,700 firm-fixed-price contract, which will see it install a miter gate installation and replace machinery at the site. Work is estimated to be completed by January 19, 2024.
The Brandon Road Lock and Dam is a lock and dam complex along the Des Plaines River in Joliet, Illinois. The complex was built from 1927 to 1933 in conjunction with the construction of the Illinois Waterway, which allowed for barge travel between Lake Michigan and the Mississippi River.


1. Pushes liquid of the back of the impeller and helps lower the pressure acting on the back of the impeller, this reduces the axial thrust
2. Mecahanical seal has to work against a lower pressure, this ensures better sealing.
3. Abrasive materials at the back of the impeller can be pumped out, protecting the impeller.


To make energy available for pumping, we could set up solar power generation facilities near these reservoirs which will provide the energy needed during the day (off-peak period) to pump water from the lower reservoir. to the upper tank.
Since a different energy source is used for pumping, the term hybrid pumped storage system is used. During the day, solar panels would generate the energy needed to pump water from the lower reservoir to the upper reservoir.
The same water would then be released to generate power to increase the power supply to the grid to meet the demand for the two daily peaks; morning peak from 7:00 a.m. to 8:30 a.m. and evening peak from 6:00 p.m. to 10:00 p.m.
Indeed, in one of my previous articles on flood mitigation in the Kashmir Valley, I had suggested the construction of a series of small dams or cascading reservoirs on the main rivers as well as on their tributaries which could ensure flood moderation.
These same cascade reservoirs could be appropriately designed to also serve as reservoirs for pumped storage. In fact, these reservoirs would be like multi-purpose systems in that they would help with flood moderation, sediment control and at the same time increase our electricity production, especially during times of peak demand.
In addition, the area around them could be developed into recreational and tourist places.

APPLICATIONS OF DDSWMM
There is a wide range of applications of DDSWMM. The primary application of DDSWMM would be for the design of new urban drainage systems, with due consideration of minor as well as rare rainfall events. This would include sizing of sewers, analysis of inlet control requirements, determination of flows and flow depth in the major system network, design/analysis of detention storage facilities for runoff control, etc.
The overlwhelming applications
of DDSWMM to date, however, have been for the analysis/evaluation of existing
urban drainage systems, including areas which were not designed according
to the dual drainage principle, and the design of relief measures for both
the minor and the major systems, through a combination of DDSWMM and an
interface with the EXTRAN model.

The multi million ringgit flood mitigation project in Sibu has certainly changed the physical appearance of the town with the construction of a few pumping stations.
The pumping station beside the Sibu Central Market is definitely a pleasant looking station with a decent looking garden behind it. The small leisure square seems to obscure rather unpleasant look of the overhead traveling crane and other functional structures within the pumping station.
There are a total of 5 pumps here. When the water level reached 1.6m, the first pump would automatically start. The second water pump will be activated at 1.8m and the process goes on.
Each of the five pumps is capable of pumping out three cubic metres of water per second and with five pumps running simultsneously, a maximum of 15 cubic metres would be flushed out per second.
The mighty Rejang River forms the backdrop of the pump house here. With its unique landscape and the beauty of the river, it has become a tourist attraction of sorts.


Patel Engineering rose almost 17.5% to Rs.51.35 and continues to remain firmly in the green. Its 52-week high is at Rs.96.05.
The stock price has jumped up after the company announced bagging two hydro projects Rs 1793.50 crore and a tunnel project worth Rs 618.21 crore.
One hydro project tunnel order is from Tamil Nadu, for construction of Kundah Pumped Storage Hydro Electric Project (500 MW) near Oooty, costing Rs. 668 crore, funded by Rural Electrification Corporation (REC).
The second hydro project of 900 MW is in Nepal and executed through a wholly owned subsidiary of Satluj Jalvidyut Nigam. The Civil work is divided into two lots, the Company has been awarded LOT-2 where work includes construction of head race tunnel; underground power house, pressure shaft, surge shaft and other connected structures with contract value of Rs.1126 crore. This is one of the biggest FDI proposal for Nepal i.e. INR 5700 Cr.
The tunnel project is in Mumbai, for construction of tunnel from Amar Mahal to Trombay. This contract is valued at Rs.618 crore.


The goal of this project is to develop a complete pump performance monitoring system that includes anadvanced sensor package and software analysis tool to continually monitor the pump efficiency and structural wear by accurately measuring temperature, pressure, pump vibration and impeller wear simultaneously. We are currently working on the development of a system that is capable of measuring wear on the impellers based on the clearance between the impeller blades, the wear plate and the pump housing. Our design does not require any modifications to the interior of the pump and therefore it is easy to implement. The sensor package will be inexpensive to produce and easily installed on existing industrial pumps. The impeller wear sensor would have to be installed and calibrated during retrofit.
Accurate measurement of impeller wear during operation would provide accurate determination and prediction of impeller lifetime and replacement scheduling. Stand-alone instrumentation will be developed for the sensors to allow for continuous data logging. One or more prototype systems will be installed in the field for data collection.

Cone Differential Pressure Flow Meter
Cone Differential Pressure Flow Meter model no [VAC- Cone- Differential- Pressure Flow- Meter]
Size 1/2 to 24 in.
Accuracy ±0.5 %
The Cone meter produces a pressure differential across a pair of pressure measurement ports. The movement of fluid around the cone-shaped element creates a pressure differential between an upstream and a downstream pressure port. It is then processed by a differential pressure transmitter to provide the flow rate. The conical shape of the element also causes the flow meter to act as a flow straightener, preconditioning the flow and makes the Cone meter a versatile measuring instrument for many applications. Badger Meter takes pride in designing an optimized differential pressure metering solution for your system. The Preso Cone meter creates a differential pressure that is proportional to the rate of fluid flow. A transmitter measures the differential pressure and outputs an integrated electronic signal via Modbus or a 4 to 20 mA output, to a flow computer or other process controller for interpretation and readout. For compressible fluids, line pressure and temperature measurements are required for accurate flow rate calculations as well as compensation for the adiabatic change in the expansion factor. As fluid flows through the pipe flows around the cone, a pressure drop occurs. The static line pressure (P1) is measured via a wall tap located just upstream of the cone. The pressure is also measured via a sensing tap that is connected to the cone and measures pressure at a point immediately downstream of the cone (P2). The fluid flow rate is calculated from the difference between the two pressures using variations of the Bernoulli flow principles and equations.

We are glad to announce that we will supply our materials for the construction of the Grand Ethiopian Renaissance Dam 5250MW.
The Grand Ethiopian Renaissance Dam, previously known as the Millennium Dam as sometimes referred as the Hidase Dam, is a gravity dam under construction on the Blue Nile River, about 40 km east from Sudan, in the Ethiopian region of Benishangul-Gumuz.
The construction began on April 2nd, 2011 and should take 44 months. With an allocation of $ 4.8 billion, the Ethiopian Electric Power Corporation (EEPCo) launched the project and, in the end, this dam will be the biggest in Africa, with an installed power of 5250 MW and an expected production of 15.000 Gwh/year.
More precisely, there will one the main dam with two power plants at its feet. These power plants are on the left and right side of the river and are made of Francis turbines, with an overall production capacity of 5250 MW.
We supplied metals and plastic materials.
One of the main advantages of the dam will the production of hydroelectric energy, which will be sold in Europe and adjacent countries, Sudan and (maybe) Egypt included.

Three Gorges Dam, the largest hydroelectric power project in the world in terms of installed capacity, goes fully on stream this month. The gravity dam, built across the Yangtze river in Yiling district of Hubei province in China, is also claimed to be the largest concrete structure ever built in the history of mankind. Incidentally, Yangtze river is the longest river in Asia and the third longest in the world.
The cost of the project that is owned by a subsidiary of China Three Gorges Corporation is said be around $25 billion.
Although the concept of this giga-project was an old one and had been lingering for several decades, the actual construction work commenced only in late 1994. Since then, this monster hydropower project was being commissioned phasewise. With all of the scheduled 32 no. of 700MW capacity francis turbine generators, each weighing six kilotons, and 2 smaller ones of 50MW capacity each going fully operational this month, the project has finally achieved the planned installed capacity of 22.5 GW ( 32 x 700MW 2 x 50MW), rendering it the highest-installed-capacity hydel power project in planet earth leaving the 12.6 GW Itaipu hydroelectric project in Brazil way behind.
Needless to say that the vital statistics of the project have to be impressive and they indeed are. The gigantic gravity dam is around 2.3 km long, 185m tall, 40m wide at the crest and 115m at the base. The reservoir length is a-never-ending 600 km which is a tenth of the length of the river itself and the catchment area is a whopping one million sq. km. expanse. A peak flow of over 71000 cusec has been achieved into the dam’s reservoir.

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.

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.”

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.
