Bankfull Channel Geometry: Influenced by Past Flow and Sediment Conditions

Existing studies indicate that the value of the bankfull channel geometry (for example, bankfull width and depth) is an empirical function of previous years' flow and sediment conditions during flood seasons, and these conditions are usually represented by the previous n years' average discharge and incoming sediment coefficient during flood seasons7,9. This means that the bankfull channel geometry, including the width and depth of the channel, can be determined based on previous years' flow and sediment conditions during flood seasons. These conditions are typically represented by the average discharge and incoming sediment coefficient over the previous n years.
