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 .

Length of overland flow (L g) Lg value for the entire basin area is 0.14 (Table 4), which is quite low. The length of the overland flow varies within the sub-basins. It ranges from 0.12 to 0.25 km (Table 5). WebDefinitions and basic concepts. The drainage density is the measure of the length of stream channel per unit area of drainage basin. Mathematically it is expressed as: drainage density = stream length / basin area. A drainage network is a system of interconnected stream channels found in a drainage basin.
