Analysis of Hydrological Inferences through Morphometric Analysis: A Remote Sensing- GIS Based Study of Kanakanala Reservoir Subwatershed
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 6
Abstract
Morphometry means, mathematically quantifying various aspects of a drainage basin. Morphometric parameters bring an idea, to know about rock structure, runoff, infiltration rate, erosion of the soil in the watershed etc. So that the study of morphometric characteristics is in demand, in order to work out a comprehensive development plan, for optimum use of watershed resources. The analysis could be achieved through measurement of linear, aerial and relief aspects. The present study has been undertaken, to compute morphological features of Kanakanala Reservoir Subwatershed, Karnataka. Computed values of Farm factor (Rf =0.65), Circulatory ratio (Rc=0.7) and Elongation ratio (Re=1) indicated that, the watershed is nearly circular in shape. The texture (7.9) indicated the intermediate texture, lying between coarse and fine. The drainage density (Dd=2.37 km/km2) indicated that, the area has a gentle slope, low rainfall and permeable bedrock. Hence, from the study, it is concluded that, the morphometric investigation is useful to bring an idea of watershed characterization so that we could make decision, about watershed prioritization, soil and water conservation and management of natural resources etc.
