Investigation of the watershed hydro-morphologic characteristics through the morphometric analysis: A study on Rayeng basin in Darjeeling Himalaya

Morphometric Analysis of Panjhara River Basin With Use of GIS for Development of Watershed Plan

“…Basin Fs is calculated to be 3.25. When there is a lot of drainage and streams in a basin, the runoff is rapid, increasing the likelihood of floods (21)…”

“…As the ratio of stream length to bifurcation, it is a key measure in assessing a basin's potential for water storage by measuring the relationship between drainage density and physiographic development (21) . Watersheds with higher values have a greater ability to store water, whereas those with lower values have a smaller reservoir.…”

“…Values in the low, middle, and high ranges represent the adolescent, adult, and senile phases of the tributary basins' life cycles, respectively (21) .…”

“…Most of the geomorphic characteristics about a catchment can be obtained in the hypsometric curve, which also represents the entire basin slope and shows what percentage of the basin is above a certain elevation. By limiting erosion via rock characteristics, hypsometric curves aid in the study of basin erosional phases and give crucial details on basin slope and geomorphology, which are important for catchment treatment, basin planning, and the location of infrastructure for collecting rainwater (21)(22)(23) .…”

Employing Remote Sensing Technologies and Geographic Information in the Hydrological Analysis of the Hilla River Valley in Babylon Governorate

“…[13] used topographical and visual satellite maps and a Digital Elevation Model (DEM), using ArcGIS and Global Mapper, to analyze the geomorphological and hydrological characteristics of Wadi Abu Kareisha Basin, Northeast of Ali Al-Gharbi, and concluded a number of important data and information about the morphometry and hydrology of the basin, it was found that there is a close relationship between the morphometric characteristics the hydrology of the basin. [14] The analysis of morphological characteristics gives an accurate perception of the geomorphological characteristics and hydrological behavior of the drainage basin, especially in areas where hydrological data is not available due to the absence of a measuring station or the lack of access to difficult topographical conditions. [15] used Geospatial Techniques with the possibility of benefiting from the water resources of seasonal valleys for agricultural purposes in mountainous areas, based on a number of criteria used, namely (slope, Flow Accumulation, Rainfall, Drainage network, Topography of the region, Ground Cover, and the Height of the Region above the Ground Level).…”
