Use of Morphometric Parameters in Prioritizing Sub Watersheds Based On Runoff Potential and Infiltration Capacity-A Case Study in the Midland Region of Peruvamba River Basin, Kannur District, Kerala Akhil R1, Jayapal G2 1Planning Assistant/GIS, Town and Country Planning, Kakkanad 2Assistant Professor, Dept. of Geography, Kannur University agniamba@gmail.com
Online published on 14 November, 2017. Abstract Morphometry is one of the important analysis using in understanding the watershed or basin characteristics. Morphometric change of a river basin is the result of actions induced by various factors like vegetation, geology, climate etc. Hence studying the morphometry is indirectly connecting all these mentioned factors. For the present study an attempt has been made in connecting the morphometric parameters with the runoff and infiltration capacity for prioritizing the sub watersheds of Peruvamba River. Nine morphometric parameters having positive and negative influence on runoff and infiltration are taken for ranking the sub watersheds. After that the ranks scored for all parameters by each sub watersheds are added together. This sum value is taken for prioritization of sub watersheds based on infiltration capacity and runoff potential. The sub watersheds with minimum sum values have been given least priority as they have more infiltration capacity and vice versa. After the prioritization field verification has been done and the result came to be positive. Top Keywords Morphometry, watersheds, prioritization, infiltration capacity, Runoff potential. Top | |
