Urban Watershed Management Role in Urban Sustainable Development with Emphasis on Runoff Management

Urban area is considered as one of the main units of a catchment, if watershed considered as integrated watershed management of a watershed catchment. Today, urban watershed management, as one of the main watershed subdivisions, have designed and developed utilization strategies and sustainable management of watershed resources in urban catchment and their habitats in order to reconstruct damages caused by urban development and also try to find solutions by considering urban sustainable development to keep resources for the present and future in the urban environment, through the optimal use of land, and lowest damages to non-renewable resources. Considering the importance of the extension and development of urban watershed management in Iran and its close relationship with sustainable urban development, and the necessity of managers and planners awareness of urban areas, in this research, we attempted to study the role of urban watershed management in urban sustainable development with an emphasis on runoff control and optimal use of rain by extracting rainwater in the backyard, green roof, or in the direction of boosting water Underground such as the use of permeable coatings, all of which emphasized the importance of runoff management in urban watersheds, was emphsized.The results showed that the annual rainfall index is very severe in the desertification class, the index of drought persistence in the low desertification class, and the SPI drought index in the severe desertification class are located, and the geometric mean of these indicators and their synthesis intensity The desertification of the area on the horizon of 1409 is in severe class. The results of this study can help in the management of desertification processes in the region.
