Site Selection for Waterflood Spreading Structures for Feeding Groundwater Resources Using Multi Criteria Decision Making (Case Study: Eshtehard Watershade)

In this paper whit thw purpose and process AHP-Fuzzy model, introduced a propr approaches to achive a location decision- making for selecting the palce of spreading operation. With consideration in this field selected three type of water sources and hydrology, geographical and socio-economic factors in level one. Based on these criteria, there are 16geograohical informational layers including: infiltration,ground water level, discharge, water quality, slope , elevation, geology, drainage density, land use, proximity to urban and rural areas, proximity to the infrastructure and roads, proximity to cultural and historical sites, due to the information industrial town is known Eshtehard collection and classification. These matters weghting by Analytical Hierarchy Process (AHP). in order to standardization of layers of fuzzy method used in Arc GIS software enviroment. Integrated maps with WLC method usually in order to map standardizedcontained with fuzzy theory and the obtained results indicated proper areas even for flood distribution as geologically in Quaternary units (Qt3, Qal) The slope prone areas placed in 0-3 % and also the most important restiction in proper areas and extremely areasrelated to Industrial land and water for agriculture but this matter removed of the Map features. With regarding the communication of final results with land usage reveled that for 18.46% of lands in these area they are in the first priority and 20.04% are in the second priority to flood distribution operation which they will be the meadow Lands low density.
