Forecasting the industrial water demand accurately is crucial for sustainable water resource management. This study investigates industrial water demand forecasting by case-based reasoning (CBR) in an arid area, with a case study of Zhangye, China. We constructed a case base with 420 original cases of 28 cities in China, extracted six attributes of the industrial water demand, and employed a ba...

In Pakistan, on-demand availability of groundwater has transformed the concept of low and uncertain crop yields into more assured crop production. Increased crop yields have resulted in food security and improved rural livelihoods. However, this growth has also led to problems of overdraft, falling water tables, and degradation of groundwater quality, and yields generally remain well below pote...

Reservoirs are principal water resources that supply irrigation water to paddy fields and play an important role in water resources management in South Korea. For optimal irrigation reservoir operation and management, it is necessary to determine the duration of irrigation water shortages. Management of reservoir operation and irrigation scheduling should take into consideration essential varia...

Increasing competition for water across sectors increases the importance of the river basin as the appropriate unit of analysis to address the challenges facing water resources management; and modeling at this scale can provide essential information for policymakers in their resource allocation decisions. This paper introduces an integrated economic–hydrologic modeling framework that accounts f...

Water management paradigms and practices have evolved markedly from the post-World War II years to the twenty-first century. Changes have been particularly urgent and visible in water-limited arid lands. Notable trends include movement from an emphasis on technological, supply-side solutions toward sociological, demand-side management; from rigid top-down state control toward decentralized mana...

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...

abstract water pricing is a policy instrument for improving water efficiency, reducing water demand, management of the irrigation systems and recovering costs. the underlying principle of water pricing is that it should reflect the opportunity cost of water. in this study, parametric mathematical programming approache were used to estimate the willingness of farmers to pay for groundwater under...
