Catchment hydrology is the study of hydrology in drainage basins. Catchments are areas of land where runoff collects to a specific zone. This movement is caused by water moving from areas of high energy to low energy due to the influence of gravity .
Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin.It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.
The catchment is the most significant factor determining the amount or likelihood of flooding. Catchment factors are: topography , shape, size, soil type, and land use (paved or roofed areas). Catchment topography and shape determine the time taken for rain to reach the river, while catchment size, soil type, and development determine the ...
Major continental divides, showing drainage into the major oceans and seas of the world--Drainage basins of the principal oceans and seas of the world.Grey areas are endorheic basins that do not drain to the ocean.
Rain falling over a drainage basin in Scotland.Understanding the cycling of water into, through, and out of catchments is a key element of hydrology. Hydrology (from Ancient Greek ὕδωρ (húdōr) 'water' and -λογία () 'study of') is the scientific study of the movement, distribution, and management of water on Earth and other planets, including the water cycle, water resources, and ...
Catchment hydrology – study of the governing processes in a given hydrologically defined catchment Drainage basin management – covers water-storage, in the form of reservoirs, and flood-protection.
Yet, these solutions also come with trade-offs, says Georgia Destouni, a professor of hydrology at Stockholm University. If you reconstruct a lot of wetlands, you may create more breeding grounds ...
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. [7]
