Locating and prioritize suitable areas for construction of gabion check dams using ANP model (case study: Troq watershed)
Authors
Abstract
Economic funding for the implementation of watershed management projects based on the economic importance of the region (water and soil), social and tourism is done. In this study, the priority areas for the implementation of watershed management project (gabion check dams) was used multi-criteria decision analysis (ANP). In the first stage criteria that include natural factors (precipitation, slope, geomorphology and land use), the economy (close to villages, roads and Quarries) was determined. The next step is to determine the factors in site selection and prioritization of areas for the construction of gabion check dams of expert's opinion (questionnaire) and to determine the coefficient of software Super decision criteria were used. Then, overlaying maps, site selection and prioritization of sub regional final map was obtained. The results showed that the most effective agents in locating dams Gabion erosion and slope coefficient b by a factor of 407/0 and 241/0 are important. According to the final 19 percent of the region's first priority is the construction of check dams. Analysis of the final map shows that this method acceptable results with high potential for locating and Prioritization for functional respectively.
