Feb 10, 2020 · The backwater effect transmits the secondary currents backwards, resulting in the creation of a sinuous pattern upstream from the shrinkage. A tributary, the Gurri River, flows into the main river just before the constriction, and this too has been affected by the process of water storage and channel pattern change.

Feb 4, 2022 · During the closure period of the tide gate, water is retained in the stream segments of the Vier- und Marschlande catchment, leading to an afflux of water, which causes backwater effects. The numerical model includes 75 sub-catchments, 75 junction nodes, 75 mesoscale stream segments, 7 gauging stations and 7 control structures.
Jan 7, 2012 · [37] The control on whether backwater or drawdown will occur at the river mouth is a function of the normal-flow depth (h n) relative to the flow depth at the river mouth (h s), where backwater (M1 curve) occurs for h n < h s, and drawdown (M2) occurs for h n > h s [Chow, 1959]. The water depth at the river mouth is a function of river discharge as well as the dynamics of the offshore plume.

This results from different frequency of occurrence of water levels of a specified height that cause changes in a specified backwater reach. The part of backwater in close proximity to the ...
May 15, 2019 · At low flows, backwater zones cause flow deceleration and in-channel sedimentation, but at high flows, they cause flow acceleration and erosion. Over many floods, the dynamics of deposition and erosion in the backwater zone are thought to control the locations of avulsions on some large deltaic channels.

Nov 4, 2023 · In the context of global climate change, the frequency of watershed flooding events resulting from extreme rainfall has significantly increased. Especially at river or lake confluences, the presence of backwater effects greatly amplifies the flood risk. To investigate the influence of backwater effects on the hydraulic characteristics of rivers and lakes, this study focuses on the Dongping ...
