Temporal Water Demand Calculation ModelMcPherson, TimothyWatson, ShaneWitkowski, Marc
Calculation and evaluation on ecological water demand under the influence of Hydropower Development in Southwest Mountain—As an example of the main upper ... Hydropower Development in Southwest Mountain brings to some influence on ecological environment. The ecological water demand of the important ...
The chemical water demand (CWD) necessary for complete hydration of belite-calcium sulfoaluminate-ferrite clinkers is calculated, taking into account gypsum added during final grinding. A series of equations are developed to predict CWD. These require a bulk chemical analysis of the clinker, which ...
Water utilities worldwide report a range of figures for NRW and losses because the figures are influenced by a variety of factors such as the age and condition of the pipes, supply pressures, efficiency of leak and waste prevention measures, how the unmetered demand is estimated and the ...
Water availability is maximized during the warmer periods of the year when human water demand is also the highest. We note that the annual potential water yield across all the locations is of the same order of magnitude, even though there is a range of spatial and temporal variability in the...
Declining groundwater levels due to generally reduced groundwater recharge and higher water demand in summer regionally forced water suppliers to exploit their current maximum capacity during dry periods to meet the demand; locally, even water supply shortages occurred. During future dry periods, strong...
(IRP)A method for looking ahead using environmental, engineering, social, financial and economic considerations; includes using the same criteria to evaluate both supply and demand options while involving customers and other stakeholders in the process.IRRIGATION EFFICIENCYThe percentage of the water ...

To have a more comprehensive understanding of the water ecological security status of the Yellow River Basin, this paper constructs a water ecological security evaluation index system founded on the Pressure-State-Response (PSR) model. The indicators are
and calculation formulas for every part of the water resources fee are determined,the synthetic water resources fee pricing model for the Tarim River Basin is established.Research in this paper will provide a theoretical basis for the adjustment of agricultural water prices in the Tarim River Basin...
