Type 10
The watercourse may be intermittent. It has a very steep gradient (>10%), with very coarse grain size, including many boulders and rocks). The water is fresh and lightly loaded. The watercourse is very narrow, under a continuous canopy with a totally forested environment. The banks merge into the gradients framing the watercourse, with steep gradients (deep watercourse). Type: only seen in xerophilic zone.
