GEOINFORMATICS APPROACH TO DELINEATE FLOOD HAZARD ZONES OF MURSHIDABAD DISTRICT, WEST BENGAL, INDIA

摘要

Flood is known to be a serious environmental hazard. It causes substantial damage to life and property. Proper monitoring and effective management technique using remotely sensed satellite data and G1S technique is an important way of flood hazard monitoring. In the present study an effort has been made to delineate the flood hazard zone of Murshidabad district of West Bengal. The district is drained by several perennial rivers and associated with huge monsoonal rainfall. The historical record shows occurrence of several flood in the district affecting several blocks of the district. Satellite image and SRTM data have been analyzed using remote sensing and GIS software to identify the flood hazard zone and the major and minor places that are located within high, moderate, low and safe zones of flood hazard. A proper mitigation and effective flood management planning can be adopted using remote sensing and GIS to check the flood problem of the district.
