Delineation of Flood Prone Area using ...

Floods of River Jhelum in Kashmir Valley are as old as the river itself. Historical accounts suggest that the river had witnessed the devastating floods since ages many among which have created havoc in terms their resultant destruction. The area which is mainly affected by floods are the Jhelum valley floor stretching from Anantnag in the south to Baramulla in the north. The Valley is an ancient lake basin 140 kilometre long and 32 kilometre wide. In this paper delineation of flood plain of Kashmir Valley has been carried out using Geographical Information System. The aim of this paper is to determine the accuracy of using simple digital image processing techniques to map riverine water bodies with Landsat 5 TM and Shuttle Radar Topography Mission (SRTM) Digital Elevation Model (DEM) data. This paper is divided into two parts, part-I deal with the Normalized Difference Water Index of Kashmir Valley and part-II deals with Transect method of river Jhelum. The 3D DEM and recent flood affected areas were used to supplement the above methodologies.
