摘要

This study focuses on the morphometric characteristics of the Manjara basin in Latur district, Maharashtra, India, utilizing geospatial technologies. By employing orbiter imagery and terrain map, the research investigates the watershed’s bifurcating stream network, focusing on morphometric aspects. The hydrologic network density, ranging from 2.812 to 2.942 km/km², indicates moderate runoff and infiltration rates, which imply balanced erosion and sediment transport processes. Key morphometric parameters evaluated include a bifurcation ratio of 1.28, suggesting minimal branching and a more linear network; a drainage density of 2.812, reflecting moderate stream channel density; a stream frequency of 14, indicating a highly interconnected network of streams; an elongation ratio of 0.746, suggesting a compact or rounded watershed shape; a relief value of 0.059, indicating minimal vertical elevation variation; an infiltration number of 39.36, suggesting higher runoff and lower infiltration; and a ruggedness number of 0.1659, indicating relatively low terrain roughness. These parameters are crucial for effective catchment planning and management, emphasizing the importance of high-quality input data, precise preparation, and appropriate mapping scales. These insights contribute to developing strategies for sustainable watershed management and mitigating potential environmental impacts.
