Abstract: 

THE SURFACE FLOWS ARE ONE OF THE MOST IMPORTANT WATER RESOURCES IN AGRICULTURE. USING THEM MAY BE DONE BY RIVERS DIRECT APPROACH, RESERVING IN WINTER AND SPRING SEASONS (GROUNDWATER AND SURFACE WATER RESERVOIRS) AND DIRECT UTILIZATION IN FLOOD REGIMES (BANDSARS AND …). HOWEVER IF USING THEM IS POSSIBLE, IT IS NECESSARY TO DETERMINE THEIR QUANTITIES. NOWADAYS ESTIMATING OF SURFACE FLOWS CAN BE FOUND BY USING REMOTE SENSING TECHNIQUES AND HYDROLOGIC MODELING. THESE TECHNIQUES HAVE BEEN USED FOR SAADI WATERSHED IN THIS PAPER. THE REMOTE SENSING SATELLITE DATA THAT HAVE BEEN USED ARE THE IRS-1C (2004-2005) IMAGES WHILST FLOOD PREDICTION IS BASED ON U.S SOIL CONSERVATION SERVICE. THIS MODEL INVOLVES THE CALCULATION OF RUNOFF FROM CURVE NUMBERS (CN) THAT RELATES TO LAND USE, SOIL TYPE, HYDROLOGICAL CONDITION AND SOIL MOISTURE. THIS INFORMATION IS DERIVED FROM THE IRS-1C IMAGES, LAND USE MAPS AND FIELD RESEARCHES.THE RESULTS INDICATE THAT THE COMBINATION OF USING REMOTE SENSING TECHNIQUES WITH HYDROLOGICAL MODELING CAN BE USEFUL FOR FLOOD PREDICTION WHILST IT HAS CONSIDERABLE POTENTIAL IN MONITORING AND ASSESSING.
