The present work attempts to build up and categorize morphometric surface of distinct identities and potentialities considering 16 morphometric parameters as spatial data layers in GIS environment. For constructing the morphometric diversity model relative importance of the selected parameters is assessed and weighted compositing is being made. Separately, relief and drainage diversity models have been prepared and finally entire surface is categorized into some distinct morphometric sub units having their own terrain characteristics and associated cultural features. Out of total river basin only 11% area comes under highly diversified surface and maximum part of the area comes under quite monotonous surface with least variation. Highly diversified surface is prone to rilling, gullying and consequently soil erosion. It is also tried to identify whether relief and drainage model exert significant impact on morphometric diversity model. It is identified that relief diversity model carries significant impact on morphometric diversity model as indicated by high correlation coefficient (r=0.94).
