Quizplus · Accepted Answer

The wetted perimeter of a stream is the total length of the channel bottom and sides that are in contact with the water, or the amount of flow in contact with the banks and bed of the channel. It is important for calculating flow velocity and discharge. Option A refers to the thalweg, which is the line of maximum velocity down the center of the stream. Option B refers to eroding banks on the outside of a meander loop, and option C refers to deposition in an abandoned stream channel.
