cov_fact

Channel cover factor

The channel cover factor is defined as the ratio of degradation from a channel with a specified vegetative cover to the corresponding degradation from a channel with no vegetative cover. The vegetation affects degradation by reducing the stream velocity, and consequently its erosive power, near the bed surface.

A value of cov_fact = 1 indicates that there is no vegetative cover on the channel. A value of cov_fact = 0 indicates that the channel is completely protected from erosion.
