[email protected] Abstract awareness of flood risks and enable them to prepare mitigation activities. The research also prepared a Flooding is one of the serious, common, and costly general flood action plan. Using satellite images, the natural disasters that many countries are facing. One study further assessed changes in river course. of the non-structural measures for risk reduction is the delineation of flood-prone areas. Flood risk Problem Addressed mapping involves modeling the complex interaction of river flow hydraulics with topographical and land Nepal is a mountainous country. About 17% of its use features of the floodplains. From conventional land bordering India is flat Terai Plain, which is most flood hazard mapping technique based on field vulnerable to flooding every year. As the rivers emerge investigation to a knowledge-based system, the study into the plain from steep and narrow mountain integrated the hydraulic model with the Geographic gorges, they spread out with an abrupt gradient Information System (GIS) and presented a systematic decrease that has three major consequences: approach of this application with a case study of deposition of the bed load, changes in river course, Lakhandei River in Nepal.
