WebExercise 13.4 Determining Stream Gradients. Gradient is the key factor controlling stream velocity, and of course, velocity controls sediment erosion and deposition. This map shows the elevations of Priest Creek in the … Webshape and form of the channel itself also change down the course of a river, and are dependent on the gradient, flow rate and sediment load of the stream at different points. Four main types of alluvial channel form can be identified: straight, meandering, braided and anabranching. Bedrock channels also exhibit a wide variety of forms.

Braided streams tend to occur in rivers with high sediment loads or coarse grain sizes, and in rivers with steeper slopes than typical rivers with straight or meandering channel patterns.
