The morphometric analysis of the Thuthapuzha river basin using GIS gives a platform for deriving the geomorphological parameters. This Kerala river basin has dendritic type of drainage network with an elongated basin. The elongated basin is described by shape parameters such as form factor, shape factor, circulatory ratio, and elongation ratio. Lower stream frequency reveals that this basin has less structural disturbance as a result of high surface runoff and fast stream flow. Drainage texture is found to be 10.5 which reveals that the intensity of the stream network is finer indicating that the surface runoff is more. The average bifurcation ratio and stream frequency is found to be 1.83 and 2.4 respectively which describe the stream characteristics. The length of overland flow in the study area is 0.342 which shows that stream erosion is more predominant than sheet erosion in the catchment. The basin is having a ruggedness number of 3.402 which exhibits higher stream velocity, hence Thuthapuzha river basin is prone to soil erosion.
