- A unique hydraulic phenomenon known as the backwater effect can occur, leading to a reversal of flow from the main channel to the tributaries or inadequate discharge from the tributaries, consequently elevating flood risk. This poses a significant challenge for the management of watershed flood risks.

Nov 3, 2022 · Sea level rise, storm surge and river discharge can cause coastal backwater effects in downstream sections of rivers, creating critical flood risks. This study simulates the backwater effects using a large-scale river model on a coastal-refined computational mesh.
Sep 1, 2024 · Studies on backwater in plain rivers have indicated that the backwater effect is typically mutual and is determined by the discharge (Chen et al., 2023b). When tributaries are impacted by backwater from the mainstream, there is a rise in water level and a decrease in velocity.
Oct 9, 2023 · Backwater impoundments created by artificial barriers alter upstream river hydraulics, creating pond-like environments that favor generalist and limnophilic species.

Sep 18, 2024 · Using data from NASA’s Global Gridded Relative Deprivation Index (GRDI), we compiled mean values for watersheds that contain our avulsion nodes, based on the Pfafstetter level 7 (blue).
Aug 27, 2024 · However, the influx of water from the surrounding areas or backwater effects at outfalls can exceed pipe and manhole conveyance capacities and thus cause drainage ‘bottlenecks’.
Oct 24, 2019 · By inspection, the results reveal that the water levels at sections m02#, m01# and mx00# are almost the same, due to the existence of backwater effect, which is, however, larger than the value at section mx04# at the downstream separation zone.
