Moree Plains Shire Council (MPSC) is the supplier of water and wastewater services for the Moree region. MPSC owns and operates the Moree Sewage Treatment Plant (STP) which treats wastewater from three main sewerage reticulation networks. ...
Drinking water companies in the Netherlands do special projects worldwide to improve the quality of installations but also support the local engineering. In Kabatini, Kenya, a well field with eight boreholes, nearly all with high maintenance cost, needed to be analyzed for replacement with high efficiency pumps. This project was important for both the village and the investors to create a base ...

The students’ research project involved conducting slug tests at 10 wells installed in Long Lane Forest to calculate hydraulic conductivity of the aquifer. They also planned to monitor water table height at a subset of those wells to determine the aquifer’s response to precipitation events. ...
Uses the Window of Operation concept detailed below. Hydraulic model. Expected operation is driven by a MAP Sewer simplified hydraulic model. ...
A couple of weeks ago, Cornell had a request for some of Condensed Hydraulic Data Books from a P.E. in South Carolina. These slim, pocket-vest sized books have been offered by us for decades. The engineer who requested the books wrote: “I have had the pleasure of using the Cornell Pump condensed hydraulic data book for hundreds of designs since1984. ...
In order to implement and maintain the operation of the adjacent DMAs with dynamic topology, a sufficiently accurate hydraulic network model was required to calculate and evaluate optimal control, particularly as multiple control elements were in operation (e.g. both PRVs and dynamic boundary ...
When the initial sedimentation sludge is concentrated, the sludge solid load can take a larger value; when the excess sludge is concentrated, a smaller value should be used. (2) Hydraulic load: The supernatant overflow flow rate per unit time through the surface area of the unit concentration tank, the unit is m3/(m2·h) or m3/(m2·d). The maximum hydraulic load of ...
However, the reliability of the hydraulic retention time calculation, and the short-circuit and mixing indicators, is doubtful, primarily because of the liquor's high density. ...
The Soil Water Characteristics software is a hydraulic properties calculator, developed by the US Department of Agriculture and Washington State University. ...
Optimum removal of nitrate was achieved at a contact time of 2 min, pH of 6.5 and a nitrate concentration of 200 mg/l. The hydraulic loading rate was calculated to be 10 m3/h.m2 and the maximum adsorption capacity using the Langmuir adsorption isotherm model (R2 = 0.99) was 10 mg NO3/g. ...
Defining aquifer permeability distribution accurately over large areas is often debated in hydrogeology. The operational efforts to calculate hydraulic conductivity with classical aquifer tests are significant; however, accurate knowledge of permeability areal distribution is fundamental both from a hydrogeological and a modeling standpoint. ...
A RELAP5 model was developed for the thermal–hydraulics experimental facility, called Natural Circulation Circuit. A Visual Basic for application program (Xtrip) was developed to transform binary data file from RELAP5 in an ASCII file. ...
By ensuring consistent high quality across every component, and with the reassurance of the detailed hydraulic calculations presented by ACO's Design Services team, we were confident that the system would meet the demanding specification." ...
Surveys of relic canals at the Oasis of Otrar in Kazakhstan have been used to re-construct patterns of agricultural water use for irrigation between AD700 and AD1500. Hydraulic simulation software was used to calculate the water carrying capacity of historical irrigation canal networks. An analysis of modern day irrigation systems has enabled the calibration of ...
The evaluation of uncertainty is a necessary supplement to Best Estimate (BE) calculations that are performed to understand accident scenarios in water-cooled nuclear reactors. ...
This paper investigates the validity of a hydraulic simulation model to calculate the piston rod acceleration for further frequency domain analysis. At the present time, simulation results analyses of shock absorber characteristics are mostly restricted to the low frequency range for the hydraulic behaviour and the high frequency range for Noise, ...
The specific yield was estimated to be 0.28, and the hydraulic conductivity was calculated to be 204 ft/day. Non-pumping and pumping groundwater flow velocities in the circulation area were approximately 2 and 5 feet per day, ...
These tools include groundwater gradient and aquitard penetration calculations, aquifer pumping test interpretation techniques, chemical concentration plots and statistical methods, hydraulic conductivity-based travel time calculations, pumping-concentration tests, methods for evaluating leaky wells, and methods for evaluating aquitard ...
Mass flux was calculated using the hydraulic conductivity and VOC concentrations to quantify the relative contributions of VOCs from each test interval. ...

The average rate of ground water flow can be estimated from the hydraulic conductivity, hydraulic gradient, and effective porosity. Hydraulic gradient is calculated from ground water elevations measured in monitor wells. Effective porosity is usually assumed based on ranges of values cited in scientific literature or estimated ...
