Flood is considered as a major threat among natural disasters in the world. This case becomes more important and has a higher risk in urban areas due to the existence of important uses. Therefore, to reduce damages resulted from flood, this phenomenon must be managed and planned using structural and non-structural approaches. Considering the development in Iran has been carried out in high risk areas for flood and great damages entering various uses of the riverbank so, determination of flood zones and risk assessment seem to be necessary. In fact, the most important step for management and planning in this field is to obtain flood map of the region which is the required condition to provide flood risk maps. Preparation of flood risk maps and the limits of flood design criteria help us to have more confident computations. Generally, determination of high flood risk areas can prevent development of these areas or if development is needed, some management strategies can be considered for construction in these areas. In the resent study, hydraulic simulation of Nekarood flow is accomplished using HEC-RAS, and GIS software and HEC-GEORAS extension. Then, flood zone map of the region is achieved. The equation of flood risk (200 years) is applied for residential, commercial, industrial, public and agricultural uses which causes to prepare flood risk map of the region. Ultimately, the achieved information can be used for flood crisis management.

Keywords: Flood Management, Flood Risk Map, Flood Zonation, Nekarood.
