Due to water use increasing, attention to optimal water resources allocation is needed. In recent decades, the use of intelligent evolutionary methods for optimization of water allocation was focused more by researchers. The aim of this study is to development on water resources planning model that determined the proper cultivation, optimal exploitation of groundwater and surface water resource...

The role of water pricing for managing water resources is widely recognized in many areas of the world because of the increasing scarcity of water resources, a high competition between water uses and environmental degradation. Based on the analysis of cost of water, this paper explores which types of cost should be reflected in the water pricing enhancing the sustainability of water resources. ...

Background and Objective: Water quality assessment is an important step for optimal and proper use of water resources for drinking and selection of suitable and consistent water quality patterns. Therefore, the necessity of studying water quality characteristics in water resource management programs has been highly considered. Materials and Methods: In this study, the hydrogeochemical quality ...

Scarcity of water resources and huge costs of establishing new hydraulic installations necessitate optimal exploitation from existing reservoirs. Sustainable management and efficient exploitation from existing finite water resources are important factors in water resource management, particularly in the periods of water insufficiency and in dry regions, and on account of competitive allocations...

In large countries with sharp temporal and spatial variation in water resources, interbasin water transfer projects seem to be an ultimate solution to ease water shortage and secure a balanced economic development among different regions. However, such projects are prone to problems and controversies, and may challenge the established basin management, legal system and policy making procedure w...

Global climate and environmental changes are endangering global water resources; and several approaches have been tested to manage and reduce the pressure on these decreasing resources. This study uses the case study of Xi'an City in China to test reasonable and effective methods to address water resource shortages. The study generated a framework combining ecosystem services and water resource...

A monitoring network that resolves the spatial and temporal variations of the water quality is essential in the sustainable management of water resources and pollution control. Due to cost concerns, it is important to optimize the monitoring locations so to use the least number of stations required to obtain the most comprehensive monitoring. The optimal design of monitoring networks is commonl...

The past thirty (30) to forty (40) years has been a period when emphasis was placed on the development of available water resources all over the world. Despite the benefits, the environmental, social and cultural impacts have had a mixture of desirable and undesirable effects. These considerations must therefore be integrated into the development process so as to make water resource use sustain...

Pore fluid pressure in a fault zone can be altered by natural processes (e.g., mineral dehydration and thermal pressurization) and industrial operations involving subsurface fluid injection and extraction for the development of energy and water resources. However, the effect of pore pressure change on the stability and slip motion of a preexisting geologic fault remains poorly understood; yet, ...

Many countries are not able to manage their water resources to sustainably meet current and future demands because they lack a comprehensive assessment of the quality and availability of their resources. The need for comprehensive assessments is well recognized, but often the required information is unavailable owing to gaps in hydrological information and understanding. These gaps are particul...
