Flood is one of the most widely distributed hazards around the world and its management is an important concern for all decision maker this phenomenon. In Iraq, especially in Salah Al-Din Governorate, during the Spring 2019, the amount of water flowing has been increased into Tigris River, this led to a rise in the river level as a result of rains in close range and snow melting, as well as an increase in the drainage of the Small Zab, which is flowed into Tigris River at Salah Al-Din Governorate. Therefore, the flood hazard mapping and flood shelter analyses have been accomplished through the assessment of damage and determination the optimal location to make flood escape for mitigation the flood hazard processing. The Remote Sensing (R.S) technique and Geographic Information System (GIS) have been utilized to assess the damage by using the NDVI and NDWI indices. Arc Hydro tool in GIS software with the hydraulic model HEC-Ras software have been also utilized to find the flood escape and modeling the flood shelter. The result shows that the damaged areas at Salah Al-Din Governorate for agriculture land and flood inundation map.
