Abstract

In this paper we first designed all the required data in GIS environment and secondary software such as HEC-GeoRAS and ArcHydro and formatting of location information database for river path, cross sections, river slope, banks and discharge rate input to HEC-RAS hydraulic model, we ran the model. After running of model we got results on flood zoning, flow depth in each point which were sent to GIS environment again in the form of satellite image and finally 3D simulation of considered zone for flood occurrence situation was determined.
