Single iteration of the GBEM algorithm

gbem0.Rd

Run the gravel-bed river bank erosion model to determine channel changes for a constant flow over a small duration.

Usage

gbem0(flow, duration, cross_section)

Arguments

flow

Discharge carried by the stream.

duration

Time for which flow acts on the stream channel (hrs).

cross_section

A "cross_section" object.

Value

A list of the following components:

  • dw_pred: predicted widening.

  • dw_const: change in width constrained by transport capacity, the most

  • v_b: transport capacity * time. Volume of transport that can be moved by the river.

  • cross_section: The original cross section.
