FLOOD PLAIN ANALYSIS OF DELTA REGION OF MAHANADI BASIN USING SATELLITE IMAGERIES

Abstract

Man has had to live with floods since the very inception of his existence. The impact of floods has been accentuated by ever-increasing activities of man in flood-plains of rivers to meet his requirements of food and fibre. Destruction of property and loss of life from floods continue to increase despite substantial invest-ments on flood protection works. These protection works, mainly structural in nature have failed to keep paw with continued deve-lopment in flood plains. Therefore, a preferred method of flood damage reduction would be to adjust use and occupancy of flood-plains through management and regulation of uses rather than solely by structural works. The first step in this effort is to map the flood-plain boundaries and other associated features of major rivers which are subjected to frequent flooding. Such a mapping by conventional met", is a time consuming and expensive procedure. Remote Sesning technic especially after the advent of satellites have shown great promise to delineate flood-plain features and inundated areas in a time anc cost effective manner.
