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.

Web24 de jun. de 2024 · High drainage density implies increase in flood peaks, whereas there is decrease in flood level in low drainage density (Pallard et al. 2009). It is because long concentration time allows more opportunities to infiltrate and distributing through time the flow. Generally drainage density and flood volume have direct relation. WebSome areas have a high population density while others have a low population density. Areas of high population density tend to be located between 20° and 60°N. This area contains a large land area and a relatively temperate climate. Find out more about the factors that affect population density.
WebClassic stream order [ edit] The classic stream order, also called Hack's stream order or Gravelius' stream order, is a "bottom up" hierarchy that allocates the number "1" to the river with its mouth at the sea (the main stem ). Stream order is an important aspect of a drainage basin. It is defined as the measure of the position of a stream in ...
