Targeted credit allocation dams stone - the mortar Watershed Engineering Using Multi-criteria Decision

According to amendment of The project dams requires many credits for watershed management. Locating studies and prioritizes critical areas are Necessary before the dams must be done accurately and comprehensively. Accurately identify erosion areas in the sub watershed is essential and appropriate measures, including structural, non-structural subject or a combination of them can reduce the severity of the damage caused by erosion and sedimentation. Accordingly the following watershed basins in the execution of construction activities, determine priorities and policy requirements are, the most importance. In this study, 11 effective measures of the performance of Dams stone - mortar in the area identify. Weight by Expert Choice software, and implement dam priority sub watershed stone - mortar by the TOPS IS. According to the results of effective criteria for locating Dams stone–mortar, the criteria erosion, including sedimentation, and discharge in particular is the most importance with the weight of 0.132, 0.103 and 0.1. Finally the watershed dams to carry stone-mortar TOPSIS methods were prioritized. The results show that the erosion of the basin S 1 with 61.14 ton/ha in the first one and sub-basin S3-n is the last one for the implementation of stone-mortar dams. The administrative priority of structures is important in allocating targeted credits for the watershed step
