DIGITAL ELEVATION MODEL BASED ALTIMETRIC FREQUENCY ANALYSIS OF MANJALAR–MARUDANADI WATERSHED, VAIGAI BASIN, TAMIL NADU

Abstract :
Altimetric frequency analysis depicts frequency of heights at successive altitudes. It is one of the methods used to demonstrate the existence of erosional surfaces or levels or planes which could be correlated to the evolution of the landforms from one place to another. In this study, altimetric frequency analysis has been attempted to find out the erosion surfaces of Manjalar–Marudanadi Watershed. The analysis reveals that the maximum frequency of pixels is found below 300m and 301–400m elevation categories. The other highest frequencies are found between 401–500m, 1101–1200m and 1201–1300m classes. Therefore, it is likely that Manjalar–Marudanadi watershed has five erosion surfaces, viz., below 300m, 301–400m, 401–500m, 1101–1200m and 1201–1300m elevation classes.
