SYNERGETIC USE OF ACTIVE AND PASSIVE REMOTELY-SENSED AND MAP DATA IN THE DELINEATION OF PART OF GODAVARI PALAEOCOURSE

Map information for (1937-38 and 1965-66), Indian Remote Sensing Satel lite (IRS) data of October 1988 and 1990, Landsat-TM data of 1987 and airborne SAR data (1988) were used in the identification of river cour se, geomorphological features and palaeo channels over part of the God avari river, India. The change in river course and growth and erosion of the island/sand bar were measured. The palaeocourse of the river at test sites has been reconstructed. The measured cut-off ratio indicat es that the chute cut-off of the river course near Gannavaram is very high. Flood affected areas in the regions could be assessed by this me thod.
