Abstract
Floods are the most frequent, widespread and disastrous hazards of the world. Almost every year, Kalam River is affected by floods though its nature and impact differs due to complete different geographical and hydrological setting. This study aims to develop Hydrologic Engineering Centre’s Hydrologic Modeling System (HEC-HMS) model for Kalam River basin to analyze the effects of rainfall on surface runoff and peak discharges of the river and ultimately produce flood inundation levels to assess the flood risks in Kalam River. Being a rain-fed catchment, the flood discharges of Kalam River are highly affected by the extreme rainfall. A HEC-HMS hydrological model was set up in order to carry out the rainfall runoff analysis. HEC-HMS model gave the discharge values of each year by analyzing the precipitation values and Digit Elevation Model (DEM) of Kalam River basin. From these discharge values the flood risk of the region was estimated. Keywords:
