Tectonic geomorphology is defined as the study of landforms produced by tectonic processes, or the application of geomorphic principles to the solution of tectonic problems (Keller, E.A. and Pinter N. 1996). Geological structure plays a crucial role in determining a wide field of relief forms, even in areas where exogenetic factors are regarded as the dominant ones in the landscape (Ahnert 1998; Bloom 1998; Ritter et al. 2002). In recent years Digital Elevation Model (DEM) data and Geographical Information System (GIS) technologies have been extensively used to determine the morphometric properties of tectonically active regions. In addition the use of Remote Sensing and GIS techniques to evaluate the tectonic formation of the surface is an emerging trend in the recent researches carrying out in different parts of our country and the world. There is not a single record except satellite data and DEM in the world to evaluate the tectonic formation of the surface. So the for present study Digital Elevation Model data has used for evaluation of tectonic formation of different feature (Geomorphic Units) within the Mula river basin. Good surface analysis research should provide the following information: formation of the basin area, formation of the different geomorphic feature, spatial distribution of geomorphic features. In present article, we have used Remote Sensing and G.I.S. tool to examine the formation of the river basin using DEM analysis. Morphotectonic study plays an important role in deciphering the effects of tectonic activity in the geomorphic evolution of the drainage basins, .Morphotectonic analysis is the study of landforms produced by tectonic processes.
In this study Remote sensing and GIS analysis techniques are used in order to determine geological and morphometric analysis of Mula basin area. Aster DEM and drainage networks of the area are used for determine the morphometric properties of Mula basin located western part of Maharashtra.
The area selected for the study is located in Western part of the Maharashtra. Which come under rain shadow area water scarcity Zone, the selected area The Mula River Basin is a major tributary of Godavari River. The area lies between 190 02’8” to 190 31’ 28” North Latitude and 730 40’ 56” to 740 50’ 39” East Longitude. Elevation in varies between 464 and1473 m MSL. The location map of the study area is depicted in Figure 1.
The materials used for the morphotectonic analysis include:
a) Topographic maps of study area at 1:50,000 scale. b) ASTER Digital Elevation Model c) Lineament Map. d) Drainage Map of the Study area.
From this analysis we come to know the behavior of the area and we get information about tectonic control of the area so in this article we have calculated Mountain fronts synosity index, valley floor width to height ratio and Drainage Basin Asymmetry for Mula river Basin of the study area.
