Anthropogenic influences on the variation of runoff and sediment load of the Mahanadi River basin

Assessment of the fraction of bed load concentration towards the sediment transport of a monsoon-dominated river basin of Eastern India

“…Numerous studies have enhanced our understanding of the trend of riverine suspended sediments transport across the world, but our knowledge of bed sediment transport in such rivers is quite restricted (Wang et al, 2007;Azamathulla et al, 2013;Armijos et al, 2017;Montanher et al, 2018;Kar and Sarkar, 2021;Luo et al, 2022). Quantitatively estimating alluvial bed transport processes is crucial in fluvial engineering, managing water resources, and accurately predicting flood damage (Gordon et al, 2004;Sinnakaudan et al, 2006;MacArthur et al, 2008;Joshi and Xu, 2017;An et al, 2021).…”

“…However, some recent studies have focused on modelling suspended sediment transport of the basin (Yadav and Satyanarayana, 2020;Yadav et al, 2021;Kar and Sarkar, 2022). At the same time, the declining trend of suspended sediment load across the basin and its related influences was reported (Bastia and Equeenuddin, 2016;Kar and Sarkar, 2021). In this regard, evaluating BL is considered significant to assess the effects of dams on sediment transport and basin yield.…”

“…In this regard, evaluating BL is considered significant to assess the effects of dams on sediment transport and basin yield. Dams in the MRB played a critical role in regulating sediment transport from upstream of the catchment to the coastal zones (Kar and Sarkar, 2021). The BLT can only be estimated if the hydraulic and sediment characteristics of a river channel are understood, although, there is not a single approach to BL estimation that works for every type of river channel.…”

A Study on the Variations and Relationships between Water and Sediment in the Longchuan River, China

“…As the increasing intensity of global climate change and human activities, the change and evolution of relationship between runoff and sediment in rivers can increase the probability of droughts and floods in regions [2]. At the same time, the imbalance of water-sediment relationship can not only threaten the water quality security, exacerbate contradiction with water utilization, but also seriously hinder the reasonable development of hydropower resources so that affects the socio-economic development and social stability [3][4][5].…”
