Increased water scarcity implies that residents of arid, heavily populated regions of the U.S. will have to increase water conservation or else face the consequence of water shortfalls. Voluntarily conserved water is an impure public good since it is non-excludable and rival in consumption. This means that water conservation benefits are subject to free-riding behavior. This paper considers a d...

Accurate and detailed information of hydrological balance, and its dynamic nature is needed to develop strategies for sustainable use and management of water resources. In this concern, a fully integrated MIKE SHE model was developed to study the hydrological balance of the Chirchik River Basin, Uzbekistan. Parameters in the model were calibrated and simulated results were validated for the per...

 Background: One issue of concern in water supply is the quality of water. Measuring the qualitative parameters of water is time-consuming and costly. Predicting these parameters using various models leads to a reduction in related expenses and the presentation of overall and comprehensive statistics for water resource management. Methods: The present study used an artificial neural...

This paper describes an integrated mathematical model, OPER, for use in the analysis and planning of multipurpose water resources systems. A typical system consists of reservoirs, hydropower stations, irrigated land, artificial and navigation channels, etc., over a reach of a river or a river basin. The model takes into account the hydrological, technical, sociopolitical and economic constraint...

Vegetation deterioration and soil loss are the main causes of more precipitation leakages and surface water shortages in degraded karst areas. In order to improve the utilization of water resources in such regions, water storage engineering has been considered; however, site selection and cost associated with the special karstic geological structure have made this difficult. According to the pr...

in many flood control projects, watershed management and water resources development, calculation of the river flow discharge is of the paramount importance which requires a comprehensive hydrological modeling of the region of interest. in this respect, lack of the existence of hydrometric and meteorology measuring stations in most of watersheds, has caused numerous problems in development and ...

Considering water resource scarcity and uncertainty in climate and demand futures, decision-makers require techniques for sustainability analysis in resource management. Through unclear definitions of “sustainability”, however, traditional indices for resource evaluation propose options of limited flexibility by adopting static climate and demand scenarios, limiting analysis variables to a part...

Problem-based learning (PBL) is an instructional design approach for promoting student learning, in context-rich settings. GlobalEd 2 (GE2) is PBL intervention that combines face-to-face and online environments into a 12-week simulation of international negotiations of science advisors on global water resource issues. The GE2 environment is described examining the impact it has had on middle sc...

Having a proper waste water treatment system is crucial for making a good use of water resources. Current regulations enforce some restrictions to the industries producing waste, according to the capacities of waste water treatment plants. However, these are usually not sufficient to ensure that these capacities are not exceeded. In this paper we present a coordination system that provides a mo...

China is a country where the levels of water resources per capita are extremely low. With rapid development urbanization, resource shortages have become bottleneck existing in more and cities. This study considers comprehensive management urban flood control, supply, ecological environment, catches main contradiction between “water deficient” rich” cities, puts forward utilization pattern for b...
