AI Technical Summary
Existing technologies are insufficient to effectively predict the length of sediment scouring zones in river channels with complex vegetation morphology, leading to unreasonable vegetation layout in river wetland ecological restoration projects and affecting sediment deposition and sedimentation effects.
A method for predicting the length of sediment scour zone within river vegetation based on sediment particle size, flow velocity, and vegetation density is provided. By establishing a coordinate system, determining the flow adjustment length and flow velocity, calculating the critical velocity for sediment resuspension, and using a formula to predict the length of the sediment scour zone.
It enables accurate prediction of the length of sediment erosion zones within complex vegetation communities, reducing research costs, and is applicable to river areas that are difficult to measure, thus improving prediction accuracy and applicability.
