Used of Geospatial tools to detect the Flood Hazards in Dibru River Basin, Assam (India)

Abstract

Mapping of Flood hazards is an essential component of land use planning. It creates awareness among the mass people about the impact of floods within the region. This study mainly focuses on the flood hazards within the Dibru River Basin. The region is the plain region near the bank of the river, or in the low land area where flood inundation is being observed. The primary aim of this study is to categorize the region into a very high flood zone, moderate flood zone and low flood zone. Different parametric are used in order to prepare the flood hazards mapping. GIS plays a vital role in processing all these parameters at one platform. GIS tool is frequently used to prepare flood hazard maps. It provides an effective way of assembling information from different maps. It can support planning and development by identifying high-risk locations and steering development away from them.
