Popis: Abstract Integrated management of urban watersheds and effective productivity of its resources, especially water resources, requires knowledge of its hydrology. In this regard, flood events and urban runoff produced at the time of floods from the point of harvesting and consumption of critical are very important. In this study in order to evaluate the possibility of using the most appropriate rainwater harvesting systems in Arak watershed, by collecting basic information from the watershed overlooking the city, surrounding watersheds were grouped by using the cluster analysis in homogeneous areas. In each region using the soil conservation service model, the rate of base time and return periods was calculated. Also, using an analytic hierarchy process and quantitative and qualitative criteria, different systems of urban water harvesting were determined for each homogeneous region of Arak watershed.
