Abstract :

The most problem, must be considered in the watershed reclamation is priority of type and amounts of difficult in the each of sub basin in the watershed. In the watershed to depend on characteristics, such as geology layers erodibility, high slope, un prosivity of facies and un natural factors such as way of land use and… some problems such as soil erosion, flood happening and… existed. Therefore in this research with using of MPSIAC model the amount of spatial sediment, with using of regional flood analysis, the amount of runoff, the amount of agricultural land for unnatural and human factor and in the end, flood coefficient in each of sub basins in the Maroof watershed considered. Then for each of factors average and standard deviation earned and normalized figures, then with earned matrices, the amount of important of each criteria in sub basins was earned quantitative. In the end with summation of total range variation in each of sub basins, amount of quantities importance of factors determined and reclamation and prevention plan in total area in four priorities earned. So the first priority (importantly) relevant to M3-1 and M3int sub basins and final priority (importantly) relevant to M1 sub basin.It seems that Iran can change the threat to opportunities by thinking about national profits and adopthing useful strategies.
