Estimation among the Geomorphological Traits of Rapti River Basin Utilizing Geographic Technologies

Abstract

This study used a combination of cutting-edge technology and tools, including remote sensing and geographic information systems (GIS), to ascertain the geomorphological features of the Rapti River basin. The watershed area, perimeter, stream order, basin length, stream length, mean stream length, bifurcation ratio, stream length ratio, form factor, drainage density, stream frequency, circularity ratio, elongation ratio, compactness coefficient, constant of channel maintenance, length of overland flow, etc. where among the various geomorphological characteristics found in the represent study. Studying geomorphology is crucial to comprehending how watersheds behave hydrologically. Measuring the drainage network's linear and shaped features as well as the contributing ground slopes can help with the morphometric study of a drainage basin and its stream system. Sub watersheds could be prioritized using morphometric analysis by calculating linear and shape characteristics. The morphometric parameters of a watershed are useful in describing a watershed when there is a lack of extensive hydrological data. A basin's morphological feature reflects its characteristics, which can be used to combine hydrological response. When quantified and expressed in morphometric parameters, basin characteristics can be examined to see how they affect runoff. Surface runoff, infiltration, and erosion susceptibility within the basin can all be qualitatively assessed through the interpretation and quantitative analysis of five drainage parameters. We learned about the wide range of uses for geographic information systems, global positioning systems, remote sensing, and other instruments. GIS and remote sensing methods are widely used in NRM due to this application diversity. These approaches aren't used in case of Rapti basin which will help in better planning and management of resources of the basin.
