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]
The maximum rate at that water can enter soil in a given condition is the infiltration capacity. If the arrival of the water at the soil surface is less than the infiltration capacity, it is sometimes analyzed using hydrology transport models , mathematical models that consider infiltration, runoff, and channel flow to predict river flow rates ...
Limnology includes the study of the drainage basin, movement of water through the basin and biogeochemical changes that occur en route. A more recent sub-discipline of limnology, termed landscape limnology , studies, manages, and seeks to conserve these ecosystems using a landscape perspective, by explicitly examining connections between an ...
Stream power is the rate of potential energy loss per unit of channel length. [7] This potential energy is lost moving particles along the stream bed. = where is the stream power, is the density of water, is the gravitational acceleration, is the channel slope, and is the discharge of the stream.
Water pollution occurs when water bodies, such as rivers, lakes and oceans are contaminated with harmful substances. These substances degrade the water quality and are toxic to humans as consumers and to the environment. [7] The contamination in a river can come from a point source or non-point source pollution.

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 ...

Fresh water is a finite and vulnerable resource, essential to sustain life, development and the environment. Water development and management should be based on a participatory approach, involving users, planners and policy-makers at all levels. Women play a central part in the provision, management and safeguarding of water.
