Combined Use of Surface and Groundwater
نویسنده
چکیده
The world’s fresh water resources are unequally distributed both in time and in space. Until recently water resource management focused on reallocating water to when and where it was required, a supply-side or fragmented approach. Nowadays there are signs that water resource availability is dwindling – due to both population growth and increased per capita water use – and ecosystems are being damaged. To face this challenge a new holistic approach is needed. This approach includes the integrated or combined use of surface and groundwater resources and takes account of social, economic and environmental factors. Moreover, it recognizes the importance of water quality issues. In this context, the paper examines the main aspects and problems concerned with the planning, design, construction and management of combined use of surface and subsurface water resources, along with its environmental impacts and constraints to sustainable development.

Lack of the proper conjunctive use of surface and groundwater resources causes large water stresses in one of these resources. Conjunctive use of surface and groundwater, especially in arid and semi-arid regions, is a scientific and practical solution for sustainable water resources management. The aim of this research was to prepare some mathematical modeling to apply the conjunctive use of su...

Compared to surface water, groundwater resources are the primary source of water supply in arid and semi-arid regions of Iran, hence the importance of the management of these resources . In this regard, we assessed the effects of landuse changes on the qualitative and quantitative status of groundwater resources in Eshtehard region, Iran. Through processing and analyzing the satellite images, ...
متن کاملSustainable Management of Groundwater Resources Using Multi-Criteria Programming (A Case Study of Kashmar Plain)
Frequent droughts and their consequences result in the loss of groundwater, the deficiency of nutrients, the drying of surface water resources, and substantially more exploitation of the groundwater resources, which, altogether, cause the mobilization of saline waters to groundwater tables. This will impair the capacity of the aquifers and the quality of the water. The VIKOR method was applied ...

Water plays a vital role in the development of activities in an area. The surface water resources are inadequate to fulfill the water demand. Productivity through groundwater is quite high as compared to surface water, but groundwater resources have not yet been properly exploited. Keeping this view, the present study attempts to select and delineate various groundwater potential zones for the ...
