Abstract
Dissection Index is a scale of measure of degree of roughness of the earth surface. The degree of roughness of earth surface is consolidated outcome of morphometric elements like – average slope, relative relief, absolute relief, drainage density and lithology. The dissection index is very useful variable in the study of the terrain. The purpose of researcher is to explore the effect of morphometric elements on the dissection index. The formula put forth by Dove Nir (1957) has been adopted to find out the dissection Index. The Wentworth Method has been adopted to calculate the average slope. Study reveals that the coefficient of correlation between relative relief and dissection index is 0.882. It is 0.627, in case of average slope and dissection index. The coefficient of correlations is 0.527 in respect of absolute relief and dissection index. Investigation reveals that relative relief has highly impacted the dissection index in the area. Average slope has moderately influenced the dissection index. The value of coefficient of correlation between drainage density and dissection index, suggests the less impact of drainage density on dissection index.
