Accurate forecast of water demand is one of the main problems in developing management strategy for the optimal control of water supply system. In this paper, a hybrid model which combines empirical mode decomposition (EMD) and least square support vector machine (LSSVM) model is proposed to forecast water demand. This hybrid is formulated specifically to address in modelling water demand that ...

To improve the water resource management of the inland river basins of northwestern China, a Decision Support System (DSS) is developed to provide an operative computer platform for decision makers. The DSS is designed according to actual water resource management problems and is seamlessly integrated into a user-friendly interface implemented in the Visual C# programming language. The DSS comp...

Understanding the knowledge of climate-change impacts on water-resources is a priority. This article goes step further with main objective this study to explore water-practitioners’ viewpoints regarding water supply-side and demand-side management measures in coping future climatic achieve urban security. Interviews were conducted water-professionals from regional authorities Queensland, Austra...

the main goal of this study was to investigate the way of affecting of water in production of cucumber. from aspect of econometrics, mutual relationships of production function and expenses have been analyzed in which translog cost function has been used. this function has been estimated using the conditional input demand functions, the shefard theorem, chemical fertilizer, animal fertilizer, l...

Up to now most of the existing water supply network analyses have been based on demand-driven simulation models. These models assume that nodal outflows are fixed and are always available. However, this method of simulation neglects the pressure-dependent nature of demand that is characterized by changes in actual nodal outflows particularly during critical events like major mechanical or hydra...

nowadays, transportation sector consumes about 27 percent of the whole energy in iran. therefore, after domestic and business sectors which consume about 40 percent of the whole energy, transportation is placed in the second rank. however, the financial value of transportation is of the highest importance. moreover, having 55percent of gasoline product consumption transportation has been also r...

We model long-run electricity supply and demand for the western United States. We evaluate the costs of carbon-reducing and water-conserving scenarios. Carbon-reducing scenarios become cost-effective at carbon prices of $50–70 per ton CO2. Water-conserving scenarios are only cost-effective above $4000/acre-foot of water. Electricity planning is central to climate policy, but much less so to wat...

A simulation and optimization model was developed and applied to an irrigated area in Delta, Utah to optimize the economic benefit, simulate the water demand, and search the related crop area percentages with specified water supply and planted area constraints. The user interface model begins with the weather generation submodel, which produces daily weather data, which is based on long-term mo...
