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. | Determination of the geomorphologic parameters of the Thuthapuzha river basin in Central Kerala India using GIS and remote sensing
