The flood situation in the Ganges basin worsened further as the water level of the rivers in the region continues to rise due to heavy downpour and onrush of water coming from upstream.
A rising trend of water levels in Pankha, Rajshahi, Hardinge Bridge and Talbaria Goalunda points was recorded in the last 24 hours ending 9 am today, Superintendent Engineer of Bangladesh Water Development Board (BWDB) Mukhlesur Rahman told BSS.
The water level of the Ganges River increased by 14 centimetres at Pankha point in Chapainawabganj, while 10 cm at Rajshahi point, five cm at Hardinge Bridge point and 12 cm at Talbaria point.
The water level of the Padma River went up by five cm at Goalunda, Bhagyakul and Mawa points, according to the BWDB data.
But, Mukhlesur said, the Ganges River was flowing 183 cm and 171 cm below the danger level at Rajshahi and Pankha points, while 21 cm above the danger mark at Talbaria point this morning.
Besides, the water levels of the Korotoa River and the Jamuna River flowing through Bogura and Sirajganj districts were on the rise, worsening flood situation in the two districts.
Arifuzzaman Bhuiyan, executive engineer of Flood Forecasting and Warning Centre (FFWC), said the water level in the Korotoa River increased by five cm at Bogura point.
He said the Jamuna River water rose by two cm at Sariakandi in Bogura, six cm at Kajipur in Sirajgonj and five cm at Sirajganj point, and the river was flowing 119 cm, 100 cm and 88 cm above the danger mark at Sariakandi, Kazipur and Sirajganj points respectively this morning.
The water level of Gur River increased by three cm at Shingra point in Natore and the river was flowing 93 cm above the danger mark. The Atrai River was flowing 106 cm above the danger level at Baghabari point in Sirajganj district with four cm further rise.
Water level in the Mohananda River also went up by five cm at Rohanpur and seven cm at Chapainawabganj.
Of the 14 river points monitored in Rajshahi division, water levels increased at 11 stations, while decreased at two stations and remained stable at one point.
The flood situation remained mostly stable in eight northern districts with further fall of river water in the Brahmaputra basin during the last 24 hours ending at 9 am today, BSS Rangpur correspondent reports.
Water levels of major rivers in the basin marked fall during the period with a possibility of improvement of the flood situation in the next 48 to 72 hours, according to the FFWC.
But, the major rivers in the basin are still flowing above the danger mark at 10 points in Kurigram, Gaibandha, Jamalpur, Bogura and Sirajganj districts at 9 am today.
Water levels of the Brahmaputra decreased by 7 cm at Noonkhawa point and 5 cm at Chilmari, and it was flowing 58 cm above the danger level at these points.
The water level of Dharla River marked fall by 18 cm at Kurigram and Ghaghot River went up by one cm at Gaibandha as the rivers were flowing above the danger levels at these points.
The Jamuna River water was flowing 104 cm above the danger level at Fulchhari point, 112 cm above at Bahadurabad point, 119 cm above at Sariakandi point, 100 cm above at Kazipur and 88 cm above at Sirajganj points at 9 am today.

The pipeline booster pump is a horizontal pump, single-stage double-suction, high-flow, high-speed chemical pump, API610 standard BB1 pump. Most of the pumps on the market today use four or six speeds. Low-speed pumps are difficult to design, but the pump head size is large and the manufacturing cost is high. Due to the extremely strict requirements on pump efficiency, it is necessary to meet the national standard A line standard, making the hydraulic design of the pump a difficult point.
Today, CFD technology has been widely used in the prediction of pump performance, the design and optimization of hydraulic components. Based on the numerical simulation technology and the mature experience of the design and manufacture of the double-suction pump of the large pump-resistant industry, this paper designs and optimizes the hydraulic design of a certain type of pipeline booster pump. It has been verified by experiments that the comprehensive performance has reached the international leading level.
2. The impeller design and performance prediction
Design parameters are as follows
Flow Q: 3600 m3/h Head H: 230 m Speed r: 2990 rpm Required NPSH NPSHr: 35m
Calculate the specific speed, and compare the existing mature and efficient hydraulic model, decided to design the impeller by similar conversion method.
The three-dimensional modeling of the impeller obtained by similar conversion is shown in Fig. 1. Then use the grid generation software ICEM to mesh the impeller 3D model, as shown in Figure 2. The impeller uses a non-structural tetrahedral mesh to mesh the locations where the flow parameters of the blade face, back and blade inlets change dramatically. Automatically generate meshes, modify the mesh automatically or manually, so that the overall quality of the mesh reaches 0.4 or more, and the final mesh number is 602681. Introduce the grid into the CFX-pre software, set the impeller inlet surface property to the inlet flow velocity v=13.7m/s, the impeller outlet surface property to open, the rotation speed n=2980rpm, and simulate the impeller separately using the standard k-ε turbulence model. Convergence within 100 steps.
The calculation data was imported into the CFX-post software for analysis. Observe the pressure distribution of the blade and the front and rear cover plates, and the impeller flow line, as shown in Figures 3 and 4. It can be determined that the overall performance of the impeller is good, the pressure is evenly changed, and the streamline is stable without vortex. Using the Liquid Pump Performance module in the CFX-POST software, the impeller efficiency is 96.9%. Since the impeller is simulated separately, only the flow field and pressure distribution are observed, and the obtained outward characteristics of the lift are not accurate and are ignored here.
3. Pump body hydraulic design and performance prediction
3.1. Pressing room design
Base circle diameter D3
The reference model pump body hydraulic model is similarly converted and selected by structural parameters
The base circle D3 = 1.1 × D2 = 1.1 × 470 = 517 mm, and rounded to take 520 mm.
Pressurized chamber inlet width
After similar conversion, take the cross-sectional width of the vortex chamber b3=146mm
Calculation of the cross-sectional area of the vortex chamber
Because the pump body needs to be equipped with four types of rotors of 0.5 Q, 0.7 Q, Q, and 1.25 Q, the area of the throat section is appropriately enlarged on the basis of similar conversion to meet the performance requirements of the large flow rotor. According to D3, b3 and the cross-sectional area, the radial dimensions of each section can be calculated.
Starting from the initial section, take a section every 45° to ensure a uniform change in the cross-sectional area of the volute. The initial hydraulic design of the pump body is over.
3.2. Prediction of hydraulic performance of pump body
In order to verify the hydraulic performance of the pump body, the pump body components are three-dimensionally shaped. The designed impeller and the pump body components are combined and output in *.stp format, and imported into the ICEM software for mesh division, as shown in Fig. 5. The fluid area of the inlet and outlet pipelines adopts a structured grid. The impeller, the volute and the semi-spiral suction chamber adopt a non-structural tetrahedral mesh, and the volute tongue is encrypted. The grid is manually modified to achieve the overall quality of the grid. 0.4 or more. The overall mesh number is 2486227, of which the outlet section is 98400, the impeller 563092, the inlet section 141825, the volute 917451, and the suction chamber 417790.
The grid is imported into CFX-pre software, using the standard k-ε turbulence model. The inlet boundary is set to the inlet speed according to the flow rate, the outlet boundary is set to open, and the target pressure is set to 23 atm. An interface is provided between each two adjacent model bodies. The interface models between the non-rotating body and the non-rotating body are set to general connection, the frame change model is set to none, and the interface models between the non-rotating body and the rotating body are set to general connection. The frame change model is set to frozen rotor. The model is simulated at six flow points of 0.6Q, 0.8Q 0.9Q, 1.0Q, 1.1Q, and 1.2Q. Calculate the 2000 step. Although the calculation does not converge but the inlet and outlet pressure is stable for a long time, the calculated data can be used.
The calculation data was imported into the CFX-post software for analysis. The external characteristic parameters were obtained using the Liquid pump performance module. The results were lower than the design requirements, and the pressure distribution and flow lines in the volute were analyzed, as shown in Fig. 6.
The fluid creates a large vortex at the diffuser, and the pressure distribution does not change uniformly from the VI section. That is to say, the hydraulic design of the volute has defects, resulting in a large amount of energy loss, which is the direct cause of the low efficiency of the hydraulic design.
4.The pump body hydraulic optimization and prediction
Based on the analysis of the convection field, it is decided to change the cross-sectional area after the IV section of the volute and increase the helix angle of the tongue to improve the energy recovery efficiency. After redesigning the volute, the new method is simulated by the same method. The optimized volute pressure distribution and streamline are shown in Fig. 7.
The pressure distribution of the volute is obviously uniform, and there is no obvious vortex. It can be seen that energy is efficiently converted from velocity energy to pressure energy, and the efficiency is improved. The external characteristic parameters are compared with those before optimization, as shown in Fig. 8. The optimization solution has reached the design requirements.
5. Performance test and comparative analysis
After the trial production and test of the full-scale prototype, the comparison between the measured results and the theoretical calculations is as follows:


Graz/Vienna, September 4, 2017. International technology group ANDRITZ has received a contract from the state-owned Chinese energy utility company Fengning Pump Storage Co.

Downstream excavation confinement (Viereth, Main)
For the project "Refurbishment of Viereth weir - gate replacement", the lack of an "n-1" condition on the Viereth weir resulted in an excavation solution, which would allow for flood release via the excavation pit in a flood event.
By implementing a special solution as a downstream excavation confinement with a rigid steel sill, mobile gates and removable pillars, and in combination with the floating upstream inspection gate, a theoretical discharge capacity of 300 m³/sec via the construction site is achieved. This allows for upgrading the weir system without any additional bypass so that the discharge capacity of approx. 1,200 m³/sec (summer floods) and the related flood protection for the town of Bamberg upstream of the Viereth weir system is maintained.

This paper presents a mathematical analysis of water supply reservoir operation. The analysis illustrates one-stage, two-stage, and three-stage formulations of multiple-period reservoir operation depending on the effects of operational constraints. There is a one-stage model when storage capacity constraints are nonbinding. Release decisions depend on total water availability and exhibit equal marginal utilities. Binding upper (lower) storage capacity constraint blocks the effect of decreased (increased) water availability in the subsequent stages on release decisions in the preceding stages. When one storage capacity constraint is binding, multiple periods become two stages and a gap occurs between marginal utilities of water. When there are one upper and one lower binding storage capacity constraints, reservoir operation is characterized as a three-stage model. Effects of forecast uncertainty and ending storage on reservoir operation are affected by reservoir storage capacity. When the storage capacity constraints are nonbinding, the reservoir can regulate streamflow in an extended timeframe, and current release decision is affected by forecast uncertainty of total streamflow and ending storage. When the storage capacity constraints are binding, the reservoir can regulate streamflow only in a short timeframe, and current release decision is primarily affected by forecast uncertainty of streamflow in the current stage. © 2014 Tongtiegang Zhao and Jianshi Zhao.

The design of Flow Control Devices (FCDs) requires performance data of an FCD’s internal nozzle under a wide range of flow scenarios. The current study specifically considers the effect of nozzle diameter and wall profile on the induced pressure loss, and subsequently the recovery performance of an FCD.
For this study, a flow measurement facility is developed to test the performance of different orifice/nozzle geometries. The flow of single- and two-phase fluid at various flow rates and mass fractions, is experimented. The pressure drop data from the experiments is used to produce performance curves that characterize pressure loss across the geometries. The pressure loss for two-phase flows are compared to their single-phase counterparts to characterize the performance of the tested geometries in the two scenarios.
A detailed protocol for performance testing of FCDs is followed as per Advanced Well Equipment Standard (AWES: recommended practice3362). The testing protocol was utilized to characterize the performance of different FCDs geometries under single- and two-phase flow conditions.
The results showed the pressure loss characteristic obtained from the flow loop experiments match the corresponding theories. The study has thus provided promising results for the successful application of direct flow loop testing to obtain reliable data which can be used in FCD design, performance investigation, and reservoir simulation.

Innovative approach to dam rehabilitation and the ecological improvement of riverbanks
The main objective of the project INADAR (Innovative Approach for Dam Restoration) is combining flood protection and ecology through the implementation of so-called "eco-berms". Behind the project are LEW Wasserkraft, Obere Donau Kraftwerke AG (ODK) as proprietor of the power plants and several other project partners.
Eco-berms are dams made from natural materials that allow for a rehabilitation of existing dams and the improvement of flood protection. At the same time, precious new habitat for flora and fauna can be created by using dead wood and other structural elements along the banks.
As a result, the population and diversity of plant species and fish in the area has grown considerably.
Role model for future river projects in EuropeThe environment-friendly approach to dam rehabilitation with eco-berms has been tested successfully and could be adapted for implementation along thousands of kilometers of riverbanks in Europe that meet the requirements for eco-berms.
In 2015, the project started with the construction of two pilot sites near the power stations Oberelchingen und Offingen along the river Danube in Bavaria, Germany by LEW Wasserkraft GmbH, and has since been implemented at several other sites. Through sharing our positive experiences and project results, our aim is to provide valuable impulses towards a more sustainable future of hydropower.

Huge investments in power generation avert crisis
The huge investments in the power sector and increased generation
capacity of the Ceylon Electricity Board (CEB) in the recent past has
averted a power crisis that would been inevitable due to the severe
drought now prevailing, said CEB General Manager Shavindranath Fernando.
He said that water levels of reservoirs in terms of hydro power
generation has reduced to 26 percent.
“The total hydro power capacity of the CEB is 1,257 Gwh and it has
now come down to 328.3 Gwh and is further declining by 4.51 Gwh per day.
No significant rain has been reported in the catchment areas of the
reservoirs. There will be no power cuts and we expect rain to start
soon,” Fernando said.
Water levels of all reservoirs have reduced sharply and the water
level at the Castlereagh reservoir was 15 metres below spill level and
at Mausakele 16 metres below spill level.
The water level in reservoirs in the Mahaweli complex was much lower
and in Victoria it was 33 metres below spill level, Kotmale 20 metres
and Randenigala 10 metres.
The water level of the Samanala reservoir was 21 metres below spill
CEB generation mix last Tuesday was 4.51 Gwh hydro, 31.48 Gwh thermal
(including coal) and 0.32 Gwh wind and the total generation was 36.31
Gwh.Electricity supply depends heavily on thermal power and it accounts
for 86.7 percent of power generation while hydro power is limited to
Wind power accounts for only 0.9 percent. The decline in hydro power
generation is offset by coal power generation of Norochcholai, he said.
The cost of a unit of thermal power is around Rs. 24.00 while for
coal power it is around Rs. 6.50-7.00. The unit cost of hydro power is
around Rs.1.50. He said that the Norochcholai coal power plant is now
functioning at full capacity. Renovation work at the Kukule Ganga power
station has been completed while renovation work at the New Laxapana
tunnel will be completed soon, he said.

Custom designed water control infrastructure provides increased safety and effeciencies for WaterNSW.
Improved safety features, increased canal efficiencies and enhanced management tools, are the key benefits of new water control infrastructure installed for WaterNSW. This multi-million dollar project was required to upgrade the Upper Canal which delivers up to 40% of Sydney’s drinking water. The Upper Nepean Scheme was established more than 125 years ago and includes a 64km canal which is comprised of 19kms of tunnels, 1km of pipe aqueducts and 44km of open canal, much of which is protected due to its historical value.
AWMA was engaged by Zinfra to design, manufacture and install a number of water control structures along the length of the Upper Canal. The upgraded sites include motorised water control gates with associated equipment i.e. trash racks, safety rails and access walkways. AWMA worked with project partners to ensure the upgraded infrastructure will deliver project objectives whilst protecting the heritage listed canal. AWMA’s customised gate solutions included rectangular and trapezoidal designs, stainless steel materials and numerous safety features.
The customised water control structures include:
- scour valves to drain the section upstream of the gate for maintenance work;
- trash racks to capture debris;
- safety features i.e. fall arrest system handrailing;
- access platforms to facilitate inspection, operation and maintenance of the gates;
- control systems including associated equipment
The new water control structures will regulate water levels in the canal to cater for varying flow rates and significantly improve the safe working environment for WaterNSW operators.
