Existing studies indicate that the value of the bankfull channel geometry for example bankfull width and depth is an empirical function of pre- vious years’ flow and sediment conditions during flood s

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.
