In recent years, flood control projects have been widely applied throughout the country. An important aspect in these projects are the labor and cost requirements. The priority of sub-basin is practically performed traditionally. In this research a mathematical method based on multicriterion decision making is proposed for the sub-basins priorities. Most of these methods automatically line up the selection and provide the result without incorporating the decision maker. The utility additive approach with greater flexibility has been considered in this study because it gives a greater importance to decision maker. This method through some steps using piecewise linear programming continously asks for choice of the decision maker. Thus, in this study 19 sub-basins of the Kan River in the Northwest of Tehran were evaluated according to 50 years return period, flood, lag time and fatal-cost damage. The results indicate that in spite of high flood volume in some sub-basins, they have not been selected due to other criteria considerations.
