A Study on Flood Risk Evaluation in Bangladesh using Remote Sensing and GIS

Abstract

Bangladesh is a flood prone country. The whole of Bangladesh is a huge river basin criss-crossed by three major river systems and their innumerable tributories and distributories. In 1988, there was the worst flood in the living memory of the people, causing awful miseries to vast area of the country, the disruption of roads and communications, the loss of properties, destruction of agricultural land, damages to crops, households and livestocks etc.
This present study deals by using NOAA-10 AVHRR imagery with other thematic maps by Geographic Information System (GIS) to estimate flood damage area in 1988 and also calculate some thematic informations inundated by floods.
