Title

Remote Sensing and GIS Studies in Evolution of Shastri River Basin, Ratnagiri District, Maharashtra: A Geomorphic Approach

Abstract

Geomorphologically the coastal part of Maharashtra seems to be controlled by tectonic and erosional processes. The tectonism along the West Coast of India is represented by faulting and upliftment of blocks in certain areas. Geomorphologically, the Deccan Volcanic Province (DVP) in the western part of Maharashtra has been divided into two major geomorphic units, viz. the low land Konkan plain and the Sahyadri upland region. Eighteen major and thirty-six minor west flowing perennial rivers originating in Western Ghats traverse the Konkan Coastal Belt (KCB). Shastri River Basin (SRB) is the seventh order coastal river basin of Maharashtra. In order to understand the tectonic evolution, the underlying structures like faults, fractures, joints, lineaments, the drainage pattern and geomorphic features of the Shastri basin have been determined. The drainage pattern is dendritic to sub-dendritic while, trellis and sub-parallel drainages have been observed at some places. Various geomorphic features of fluvial and marine origin have been identified in the area, based on the study of topographic sheets, satellite data and DEM, which have been supported by intensive field investigations. The presence of the constructional and pro-gradational features towards western part suggests emergence of the land whereas the presence of degradational features towards eastern side of the basin depict the submergence activities in the area. The presence of abnormal drainage patterns and various geomorphic features, hot springs in linear array indicates the imprint of tectonic activity.
