Egypt Installs First Hydroelectric Turbine in Tanzanian Dam
The Egypt-made hydroelectric dam will secure a clean power supply for over 60 million Tanzanians as well as help control water flow if flooding were to occur.
An Egyptian joint venture in Tanzania has begun installing the first of nine hydroelectric turbines for their Julius Nyerere Hydroelectric Power Project (JNHPP), which is set to be the largest dam in the country. The project dates back to August 2017 when Tanzania announced bids for the dam’s construction. Shortly afterwards, in December 2018, the contract was given to Arab Contractors and Elsewedy Electric at a cost of USD 2.9 billion.
In February 2019, Tanzania officially handed over the construction site to the Egyptian companies and construction began in the third quarter of 2019. It is now scheduled to be completed by 2022.
Located in the Morogoro area on the Rufiji River, the dam is 1,025 metres long and 131 metres high with a storage capacity of about 34 billion cubic metres of water. Each of the nine turbines has a capacity of 235 mw, with a total hydropower capacity of 2,115 mw.
When complete, the JNHPP will secure a clean power supply for over 60 million Tanzanians as well as help control water flow if flooding were to occur.

Application of the flow dimension concept for numerical drawdown data analyses in mixed-flow karst systems
Download Full Text
A numerical discrete conduit-continuum model is employed to investigate large-scale groundwater abstraction in karst aquifers. The application of large-scale experiments is one approach to deal with the scale problem in hydraulic parameter assessment, caused by significant contrasts of hydraulic parameters in a karst aquifer. Here, conduit drawdown is evaluated by diagnostic plots and by considering the apparent flow dimension. These tools are frequently used for the interpretation of hydraulic borehole tests by analytical solutions. In contrast to existing analytical solutions, a numerical groundwater model allows the incorporation of the effect of complex parameter distributions. The objective is to demonstrate the application of diagnostic plots and flow dimension analysis for a systematic analysis of the effect of different boundary conditions as well as sink/source terms for idealized two-dimensional mixed karst aquifer systems, which ultimately extends existing analytical solutions and, therefore, contributes to the interpretation of measured field data. The analysis is focused on the apparent flow dimension and shows the extension of the cross-sectional flow area for selected models. The results are used to evaluate the large-scale pumping test of the karstified Cent Fonts catchment (Languedoc, France). The inverse calibration of two realistic, but still simplified, catchment models reveals that the apparent flow dimension supplies useful information about the general flow pattern during the Cent Fonts pumping test. The flow dimension after the end of the storage period can be explained by a large contribution of exchange flow resulting in a strong influence of radial flow on regional, i.e., kilometer scale.

The device is specially designed with clean water and emulsion livid of 5-60 degree and oil of viscosity no more than 45 mm2/s as the working media. The liquid is filled up quickly and pressure goes higher immediately when doing the testing initially. It is to reduce the testing time, has great flow volume. When the pressure is over 1.6Mpa (the pressure can be automatically adjusted lower), the flow volume is automatically reduced in order to keep the testing slow and stable. Thus the product has two flow volumes under high and low pressure, and it changes automatically. Any kind of pressure testing can be performed under the rated pressure output. Its working temperature is 5-60 degree.
II. Technical Parameters
The series hydraulic test pump has seven models and its basic parameters are shown in Table 1. When selecting the hydraulic test pump, the rated pressure should be chosen based on the testing pressure needed. The flow requirement shall also be considered.

Is it Possible????
I want to simulate the turbulent flow in a channel, whose bed is porous and there is upward seepage through the bed along with a turbulent flow in the channel.
Is it possible to simulate the laminar flow in the porous sand bed and turbulent flow above the bed at the interface simultaneuosly to get velocity and shear stress distributions?
How to set the boundary condition at the sand & water interface which will take into account the roughness of sand and the upward seepage velocity? Please help at the earliest. Thanks in advance.

Abstract Based on comparing structural features of different tubular pumping systems and technical characteristics of cut off devices in common use, aiming at the characteristics of low head, shorter annual operation time and higher safety and reliability requirements of city flood control pumping stations, a new type shaft tubular pumping system was invented, which is composed of a shaft suction box, a tubular pump and a siphon type discharge passage with a vacuum breaker valve as cutoff device. Taking a real pumping station in Yancheng city as an example, the computational fluid dynamics method was adopted to analyze the internal flow of the new type model tubular pumping system and predict its energy performances. The time averaged Navier-Storks equations were closed by RNG k-ε turbulent model to adapt internal flow of siphon type discharge passage with larger curvatures. The method of multi-reference frame(MRF) was used to deal with the coupling of rotating impeller and static guide vane, and SIMPLEC algorithm was adopted to achieve the coupling solution of velocity and pressure. Computational results show that the internal flow of the new type shaft tubular pumping system through preliminary optimization is smooth, and the model pumping system efficiency reaches 56.0% when the design head and the relevant discharge are 1.15 m and 0.326 m3/s respectively, and up to 68.8% when the maximum head and the relevant discharge are 1.95 m and 0.296 m3/s respectively.

A Statistical Analysis of the Danube Flow Regimes in Brăila Harbour Area
MetadataShow full item record
It was in the frame of the „Restoration of the aquatic and terrestrial ecosystems complex, from Fundu Mare Island, part of the Small Wetland of Brăila - RAMSAR site 1074” project to look for solutions to improve the hydro schemes for lakes and related channels. These flow regimes are directly influenced by the flow regimes of the Danube arms surrounding the island. The main parameters of natural influence are Danube water levels and charge. The project proposes the construction of weirs which would improve water flow regimes in the island’s channels connected with the Danube. This paper shows how to optimize the construction of weirs on the basis of the analysis of the annual cyclic variation in the level of the Danube River.

The StreamClean GPT consists of a circular chamber (plus risers if required) with a diversion channel:
The main factors which allow for sediment removal are:-
Stormwater from the main stormwater drainage system enters the diversion channel wherein a baffle diverts the stormwater to the storage chamber.
In the storage chamber the stormwater is forced into a vortex action and travels around the storage chamber. Oil & grease will rise to the surface where it is retained.
Pollutants and sediment within the stormwater are forced to the inside of the storage chamber. Sediment falls to the base of the GPT where it is retained. The cleansed stormwater leaves the storage chamber via the screen and outlet spigot, through the diversion channel and rejoins the main stormwater drainage system.
The StreamClean GPT unit is designed for use in non-pressure stormwater systems.

We have built many of the world’s hydropower facilities, with projects in more than 20 countries providing more than 45,000 megawatts of installed hydroelectric capacity.
Our dam projects include earth and rockfill, concrete arch, mass concrete and roller-compacted concrete gravity dams, as well as hybrid dams of timber crib, steel facing and concrete walls. Our proprietary instrumentation and data management system, called DamSmart™, is used by large utilities and public agencies to assess the performance of dams.
The construction of the Hoover Dam in the 1930s is among our signature achievements. More recently, we performed services under a $705 million engineer-procure-construct contract for the award-winning San Roque Multipurpose Dam and Reservoir in the Philippines, one of the tallest earth and rock-fill dams in the world. For an upgrade of Cosseys Dam—the third largest dam in Auckland, New Zealand—we performed the risk assessment and designed major dam improvements for the facility, which provides 14 percent of the city’s water storage.
Currently, we are leading a joint venture serving as the construction contractor for the U.S. Army Corps of Engineer’s 2,700-foot-long Olmsted Dam on the Ohio River in Illinois—one of the busiest stretches of U.S. inland commercial navigation—and we are providing design services for a new dam that will replace the seismically vulnerable Calaveras Dam, which is part of San Francisco’s water supply system.

Validation of a three-dimensional numerical model using field measurements in a large scale river reach
Proceedings of the 1997 27th Congress of the International Association of Hydraulic Research, IAHR Part D, August 10, 1997 - August 15
San Francisco, CA, USA
A three-dimensional numerical model is developed to resolve the flow in natural rivers, in particular in the vicinity of hydraulic structures. The model solves the Reynolds Averaged Navier Stokes (RANS) equations in generalized curvilinear coordinates. It is currently being applied to a river reach approximately seven kilometers (four and half miles) long in Columbia River, WA, immediately upstream of Wanapum Dam. The model has been calibrated against field measurements for two flow discharges. The higher discharge (5390 m3s) is split between the powerhouse and the spillway, while the lower discharge (2559 m3s) is released only through the powerhouse. The field measurements are collected at six cross sections. At each vertical velocity-station, three velocity components were measured at 0.2, 0.4, and 0.8 of the flow depth. A comparison between the numerical solutions and the field data is presented, and a good agreement is observed. The obtained level of agreement indicates that the numerical model produces results that are quite satisfactory for practical purposes.

TRE Bridge Over West Fork of Trinity River
The proposed TRE double track is a 0.75-mile commuter track extending between southwest Fort Worth through I-35W & 287 to Sylvania Ave. This project includes one bridge rehabilitation and new construction of four bridges. Double Track bridges will be constructed at MP 612.0 (West of N. South Freeway), MP 612.44 (West Fork of Trinity River) and MP 612.56 (over Sylvania Ave.). At MP 612.20 (over N. South Freeway), the existing bridge will be replaced, and a new two track bridge will be constructed. GEI was responsible for creating the preliminary guideway plan and profile sheets, trinity trail realignment sheets, drainage area maps and railway cross sections for the preliminary plan set. As a part of the preliminary design, GEI analyzed the hydraulic impacts of the construction of a second track bridge across the West Fork of the Trinity River. The hydraulics were analyzed using the existing FEMA provided HEC-RAS model for the West Fork of the Trinity River and by using the North Central Texas Council of Governments (NCTCOG) Corridor development HEC-RAS model. The existing and proposed FEMA analysis found no rise in the water surface elevation for the 100-year storm, and the Corridor development model found no rise in the water surface elevation based on 2050 hydrologic values. Finally, GEI wrote the project design report, consolidating the recommendations of geotechnical, structural, hydraulic and construction discipline leads.

Why we’re doing this
Green Square sits on a floodplain that used to be a network of wetlands and creeks.
Hazardous flooding has been a constant challenge for Green Square locals with floodwaters reaching 2.3m on Joynton Avenue during storms in April 2015.
What we’re doing
Planning is underway for the construction of a new stormwater drain from the corner of O’Dea and Joynton avenues to 114 Joynton Avenue.
This work is part of new stormwater infrastructure to reduce the risk of severe flooding along Joynton Avenue.
The new drain will carry stormwater from the southern part of Waterloo and surrounding areas along Joynton Avenue to the Green Square stormwater drain.
We'll undertake further geotechnical investigations to check for any underground obstructions along the alignment of the new stormwater drain.
This will help planning and the protection of significant trees when construction begins.

Design and Analysis of Mixed Flow Pump Impeller IJTSRD
Mixed flow pump impeller is a centrifugal pump device where the transition of fluid flow takes place in both axial and radial direction. In this work a mixed flow pump impeller has been designed using CATIA V5 software tool and analyzed using the fundamentals of fluid mechanics and turbo machinery. As per many researchers there are many methods are used to design the impeller but still the optimized design of the mixed flow pump impeller blade has been a cumbersome work. The impeller blades have been designed by varying the semi cone angle. The CFD analysis is the advanced tool used in pump industry to improve the efficiency hence the CFD analysis is carried over the model to predict analytical values and to solve problems the problems that involves the fluid flow using ANSYS workbench 16.0. Because of its anti corrosive property stainless steel is used as material for impeller and water liquid used as a fluent which flow around the impeller. From the CFD analysis the velocity and pressure in the outlet is predicted. The outlet values will be useful for calculating the efficiency of the pump.
