Application of Remote Sensing and GIS for Flood Hazard Mapping: A Case Study at Baralia-Nona River Basin, Assam, India
Journal Title: International Journal of Humanities and Social Science Invention - Year 2017, Vol 6, Issue 3
Abstract
Floods are the most common natural hazards which lead to the loss of lives, properties and resources. Floods in the Indo-Gangetic-Brahmaputra Plains are an annual feature. Flood, bank erosion and sedimentation are a major problem in the plains of the Baralia-Nona basin. Heavy rainfall in the Bhutan Himalayas as well as in the flood plains of Brahmaputra Valley, lack of adequate gradient to drain out the high discharge of the rivers, increasing sedimentation due to deforestation and landslide in the upper catchment, breaching of embankments are the main causes of flood in this part of the basin. Flood history indicate that regular large floods have breached the embankments, created areas of bar development and caused bank erosion and aggradations and channel migration in the study area. This study area needs an efficient and costeffective methodology for preparing flood hazard map for Baralia-Nona Basin, where flood pose a recurrent danger. An additive model was utilized to create a composite flood hazard index of the study area. A composite flood hazard index was developed incorporating variables like elevation, population density, proximity to the rivers, number of household and cropland. The study demonstrated the potentials of GIS applications in flood hazard mapping which will also be helpful in studying the problems of agricultural land use, cropping characteristics in the area.
