# cov\_fact

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.

{% hint style="info" %}
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.
{% endhint %}
