Estimation of Erosion Susceptibility and Sediment Yield in Ephemeral Channel Using RUSLE and SDR Model: Tropical Plateau Fringe Region, India

Sub-basin prioritization for assessment of soil erosion susceptibility in Kangsabati, a plateau basin: A comparison between MCDM and SWAT models

“…Classification of sub-watershed to erodibility using SWAT model. the five critical sub-basins that are most sensible to erosion due to presence of responsible morphometric parameters in line with the results of Bhattacharya et al (2020a). On the other hand, SWAT parameters helps to determine the significant role of morphometric parameters on ES in response to sediment yield deposition throughout the basin.…”

“…4.3.2. Sediment yield analysis and its sub-basin prioritization Suspended sediment load and its movement in stream has entirely depended on several hydraulic variables like stream discharge, watershed slope, including flow and sediment regime characteristics (Sridhar et al, 2018;Bhattacharya et al, 2020a). Huge sediment load helps to accumulation of sediment yield at sub-basin level where SWAT model is applied to estimate the amount of yield following some considerable hydrological parameters (Welde, 2016).…”

“…7 showed that most of the basin area come under low to medium sediment yield priority class, whereas high and very high sediment yield classes are mainly concentrated at outlets or confluence points. Generally, absences of flow discharge, low drainage density and lower catchment area helps to generate low sediment yield, while presence of confluence points, high drainage density and large catchment area helps to accumulate of high sediment yield (Bhattacharya et al, 2020a). In terms of ES at sub-basin level, monthly sediment yield priority is classified into four classes i.e.…”

“…On the other hand, several hydrological parameters in a drainage basin, including runoff volumes, sediment delivery, sediment yield, potential evapo-transpiration and ES are assessed by various hydrological models (Kamble, 2001;Sridhar et al, 2018;Bhattacharya et al, 2020aBhattacharya et al, , 2020b; Soil and Water Assessment Tool (SWAT) as one of them which automatically extracted sub-basins boundary delineation (Tripathi et al, 2003(Tripathi et al, , 2006, and also estimate soil erosion (Ameri et al, 2018), sediment delivery (Gassman et al, 2007), and all other hydrological parameters at sub-basin level (Vigiak et al, 2017;Anand et al, 2018;Markhi et al, 2019).…”

Land use and Land Cover change and its resultant erosion susceptible level: an appraisal using RUSLE and Logistic Regression in a tropical plateau basin of West Bengal, India

“…Mean R value consistently situated in the surface water body (718 MJ mm ha −1 h −1 year −1 ) and degraded forest (725 MJ mm ha −1 h −1 year −1 ) in Tables 4 and 6. Therefore, R value indicates that low land surface located under high rainfall intensity zone than plateau fringe and undulating topography following Mahala (2018); Bhattacharya et al (2020).…”
