RESPONSE:

1. Compare and discuss those stream characteristics that decrease in a downstream direction with those that increase downstream. Also, indicate and discuss whether these changing stream characteristics tend to favor erosion or deposition of sediments.

There are four main characteristics of streams to consider (ranking, gradient, meander and age of the stream) in your discussion of the decrease or increase of the downstream direction. In other words, the streams shape and bottom profile impact the movement downstream, which either favors erosion or deposition of sediment. It is relatively easy to measure how fast the water in a stream is traveling or to measure the discharge of a stream. But what might happen to a stream's velocity if a stream's gradient changes? This happens to real streams as they flow and erode away large amounts of earth materials from their beds and sides.

1. Ranking - Streams in geographic terms are awarded order designations. A stream of the first order is a blue-line stream, which does not have any other blue-line stream feeding into it. A stream of the second order is one, which is formed by the joining of two or more blue-line streams. A ...
