Geomorphological Investigation of Kolamba Basin of Krishna River with the Help of GIS for Watershed Management
Journal Title: INTERNATIONAL JOURNAL OF RECENT TRENDS IN SCIENCE AND TECHNOLOGY - Year 2014, Vol 10, Issue 2
Abstract
Morphometric analysis helps to understand prevailing geo-hydrological characteristics of the drainage basin. In the present study, morphometric analysis has been carried out using Geographical Information System (GIS) techniques to assess the geo-hydrological characteristics of three sub-watersheds of major Kolamba basin area of Karad Taluka, of Satara district of Maharashtra. Spatial information technology that is, remote sensing (RS) coupled with geographical information system (GIS) has come out as an efficient tool in delineating drainage pattern and water resource management and its planning. The morphometric parameters of the watersheds are discussed with respect to linear, areal and relief aspects. The Kolamba watershed is characterized by dendritic drainage pattern. The various aspects of morphometric parameters such as, Drainage Density, Slope, Shape of the Basin, Bifurcation ratio, length ratios etc. along with the geological parameters gives the precise and objective overview about the watershed. This is the seasonal rain fed watershed, hence needs better management. Sustainable developments and management of the watershed is influenced by topography of the area and geomorphologic features.
