WebDrainage density. The total length of all streams in the basin divided by the total area of the basin. River mouth. Where the river ends its journey flowing into the sea or lake. Watershed. The boundary between two drainage basins marked by a ridge of highland. Drainage basin. The area which is drained by a river and its tributaries. Drainage density is indicative of infiltration and permeability of a drainage basin, as well as relating to the shape of the hydrograph. Drainage density depends upon both climate and physical characteristics of the drainage basin. High drainage densities also mean a high bifurcation ratio.
