Drainage density relates to the storage and runoff terms. Drainage density relates to the efficiency by which water is carried over the landscape. Water is carried through channels much faster than over hillslopes, as saturated overland flow is slower due to being thinned out and obstructed by vegetation or pores in the ground. [7]
A drainage basin is an area of land in which all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the drainage divide , [ 1 ] made up of a succession of elevated features, such as ridges and hills .
It includes oceanic sea drainage basins which have hydrologically coherent areas (oceanic seas are set by IHO convention). The oceans drain approximately 83% of the land in the world. The other 17% – an area larger than the basin of the Arctic Ocean – drains to internal endorheic basins.
Such a drainage system is said to have a very fine drainage texture, [6] as measured by its drainage density. Drainage density is defined as the total length of drainage channels per unit area of land surface. Badlands have a very high drainage density of 48 to 464 kilometres per square kilometre (77 to 747 miles per square mile). [5] The ...
Density can no longer remain a city-by-city decision — it has to be, as Gilbert rightly put it, “a community goal.” We have to make sure that no one else in Miami-Dade County is forced to ...
For example, he might suggest that you’re more likely to be happy by setting your expectations low or that you’ll sabotage yourself if you are envious of others and pity yourself.
Kilometre per square kilometre is an SI derived unit of reciprocal length used for measurement of density of a linear feature in an area. It is used to measure, for example, drainage density [1] or road density (i.e. kilometres of road per square kilometre of land). [2]
AMSTERDAM (Reuters) -The head of the chemical weapons watchdog said on Thursday he would ask Syria's new leaders to grant investigators access to the country to continue work identifying ...
