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 . Ver mais Drainage density is a quantity used to describe physical parameters of a drainage basin. First described by Robert E. Horton, drainage density is defined as the total length of channel in a drainage basin divided by the total … Ver mais Drainage density is tied to the water balance equation: Where $${\displaystyle {\frac {dV}{dt}}}$$ is the change in Ver mais The discharge through the central stream draining a catchment reflects the drainage density, which makes it a useful diagnostic for predicting the flooding behavior of a catchment following a storm event due to being intimately tied to the hydrograph. The material that … Ver mais Drainage density can be used to approximate the average length of overland flow in a catchment. Horton (1945) used the following equation to describe the … Ver mais A drainage basin can be defined by three elementary quantities: channels, the hillslope area associated with those channels, and the source areas. The channels are the … Ver mais Montgomery and Dietrich (1989) Montgomery and Dietrich (1989) determined the following equation for drainage density by observing drainage basins in the … Ver mais Charles Carlston (1963) determined an equation to express the mean annual flood runoff, Q2.33, for a given drainage basin as a function of drainage density.

Web11 de nov. de 2024 · Thus, the law of high infiltration, low density and low infiltration high drainage density is implied in the study area. 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. WebDrainage basin - the area of land drained by a river. Catchment area - the area within the drainage basin.
