definition | Channel depth and width refer to the dimensions of a landform that is dominated by
channelled stream flow. The limit of channelled stream flow dominance must be identified
before width or depth can be estimated. Depth is taken from the top of the stream
bank down to the average height of the line following the deepest part of the channel. The distinction between stream bank and hillslope or scarp according to dominant process requires particular care where streams are incised, especially if they are cut into terraces that could be mistaken for flood plains. For detailed studies, keep records of width and depth measurements. In other surveys, use the following classes of relative depth. |
