Web29 nov. 2024 · A simple and straightforward way is to calculate an average slopes by considering the most upstream and downstream elevations along the flow path ( Figure 20 ). However, this slope sometimes is not representative and it is often being distorted by a steep upper portion of a watershed or a highly irregular profile.

Webupstream. This is the head of the watershed, beyond which the land slopes away into another watershed. At each point on the stream the land slopes up on each side to some high point then down into another watershed. If you were to join all of these high points around the stream you would have the watershed boundary. (High points are WebFeatures.
