Abstract - This study offers an in-depth examination of Marathwada region’s morphometric characteristics, specifically focusing
on its susceptibility to drought. Using Digital Elevation Models (DEMs) and administrative boundaries, the research generated river networks and assessed various morphometric properties including Elongation Ratio, Form Factor, Circularity Ratio, Relief Ratio, Bifurcation Ratio, Ruggedness Number, Stream Frequency, Drainage Density, Constant Channel of Maintenance, Length of Overland Flow, Drainage Intensity, and Drainage Texture. These metrics were then analyzed to evaluate the district's vulnerability to drought. The results yield significant insights into the hydrological dynamics of the area, aiding in the development of more efficient water management strategies and drought mitigation measures. Key Words: GIS, morphometric analysis, DEM
1.INTRODUCTION This research undertakes a detailed and comprehensive analysis of the topographic and morphometric parameters of four key districts in the Marathwada region - Jalna, Aurangabad, Nanded, and Beed, along with their respective talukas. Leveraging the robust capabilities of Quantum Geographic Information System (QGIS), a wide array of parameters were meticulously derived to gain a deeper understanding of the physical characteristics of these basins. The parameters studied encompass a broad spectrum, ranging from topographic aspects such as area, perimeter, basin length, maximum and minimum height, topographic position index, terrain ruggedness index, and roughness, to morphometric aspects like stream number, stream order, stream length, bifurcation ratio, and mean stream length. Each of these parameters, derived from rigorous software analysis and mathematical computations, provides valuable insights into the hydrological behavior of the region. Furthermore, the study delves into areal aspects such as elongation ratio, form factor, circularity ratio, stream frequency, drainage density, constant channel of maintenance, length of overland flow, drainage intensity, drainage texture, and ruggedness number. It also explores relief aspects like slope, relief, and relief ratio. Each of these parameters, carefully calculated and analyzed, contributes to a holistic understanding of the region’s geomorphology. The implications of these parameters are manifold, influencing flood prediction, water resources management, and the assessment of land use changes on the basin’s hydrology. This research, therefore, stands as a significant contribution to the field of geomorphology and hydrology, offering a detailed, data-driven examination of the Marathwada region. The findings of this study have the potential to inform sustainable water management practices and contribute to the region’s resilience against climate change impacts. By providing a comprehensive understanding of the region’s topography and morphology, this research paves the way for future studies and interventions aimed at enhancing the region’s water security and sustainability. This research, therefore, not only contributes to academic knowledge but also has significant practical implications for the region’s development and environmental management.
2. LITERATURE REVIEW Researchers in hydrology and geomorphology use geospatial techniques for morphometric analysis of river basins, focusing on understanding basin properties for holistic hydrological assessment.
