In order to estimate the effect of an anthropogenic influence on the water balance in the Volta Basin, located in West Africa, joint regional climate–hydrology simulations were performed using the mesoscale meteorological model MM5 and the hydrological model WaSiM. The regional climate simulations show a decrease in rainfall at the beginning of the rainy season, an increase at the height of the...

Actual and projected water scarcity has accelerated the scale of hydrological infrastructure number Inter-Basin Water Transfers (IBWTs), which move freshwater from one geographically distinct river catchment or basin to another. IBWTs are supply-side programs that pose governance challenges. If all completed by 2050, volume transferred would be 48% global withdrawals. This article examines a so...

coastal areas usually involves in several kinds of water use, such as agricultural, industrial, and drinking, which are needed to be considered as important in water management systems. there is a need to study the sustainable water resources management in different terms. a combined methodology, which considers the human activities, as well as environmental problems according to some criteria,...

Economic analysis of policies aimed at sustainable use and management of natural resources requires information about the biophysical and economic aspects of alternative options. Since these biophysical and economic aspects are inter-related and inter-dependent, it is essential that these data are integrated. However, existing biophysical and economic monitoring networks and studies tend to obs...

Dissolved sulfide concentrations in the water column and in sediment pore waters were measured by square-wave voltammetry (nanomolar detection limit) during three cruises to the Santa Barbara Basin in February 1995, November–December 1995, and April 1997. In the water column, sulfide concentrations measured outside the basin averaged 3 6 1 nM (n 5 28) in the 0 to 600 m depth range. Inside the b...

The virtual water strategy which advocates importing water intensive products and exporting products with low water intensity is gradually accepted as one of the options for solving water crisis in severely water scarce regions. However, if we count the virtual water embodied in imported products as the water saved for a region, we might overestimate the saving by including the virtual water th...
