Abstract

Regional study of any geographic or geomorphic phenomena is essential in different aspects such as understanding the region, resource management, and application of the knowledge for the regional development. Understanding the physical set up of these regions is the basis of such regional assessment. In the same context, identification of morphogenetic region(s) is of interest to the geoscientists, geotechnical experts, and planners. Regional setup with respect to morphogenetic regions is not well studied in many parts of the world. The present study is carried out to understand the morphogenetic regions of Maharashtra State in India, to know the characteristics of each morphogenetic region with reference to the climatic conditions prevailed over a long time and processes operated in the region. In order to understand the climatic conditions, the climate data for 63 years (1951–2013) in the grid format has opted for analysis. The elevation data is extracted by using SRTM Digital Elevation Model (DEM) of 30 m spatial resolution. Using these datasets in GIS platform, primary morphogenetic regions for Maharashtra State have been identified. These regions are further characterized with the help of denudational processes such as weathering and their types, erosion, and mass movement which play a dominant role in those morphogenetic regions. Based on the analysis carried out, five morphogenetic regions are identified as selva, maritime, moderate, savanna, and semi-arid regions, covering the entire Maharashtra State.
