Urban runoff is surface runoff of rainwater, landscape irrigation, and car washing created by urbanization.
Biogeochemical cycle that describes the continuous movement of water on, above and below the surface of the Earth.
The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, by the physical processes of evaporation, condensation, precipitation, infiltration, surface runoff, and subsurface flow.
Type of landform consisting of the outline of a path of relatively shallow and narrow body of water or of other fluids , most commonly the confine of a river, river delta or strait.
Overland flow is a primary factor in channel initiation where saturation overland flow deepens to increase shear stress and begin channel incision.
In hydrology, snowmelt is surface runoff produced from melting snow.
Nonpoint source (NPS) pollution refers to diffuse contamination (or pollution) of water or air that does not originate from a single discrete source.
Nonpoint source pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage, or hydrological modification (rainfall and snowmelt) where tracing pollution back to a single source is difficult.
Inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent ).
Water moves continually through the water cycle of evaporation, transpiration (evapotranspiration), condensation, precipitation, and runoff, usually reaching the sea.
Process by which water on the ground surface enters the soil.
If the precipitation rate exceeds the infiltration rate, runoff will usually occur unless there is some physical barrier.
Denudation of the upper layer of soil.
Rainfall, and the surface runoff which may result from rainfall, produces four main types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.
Water located on top of the Earth's surface, and may also be referred to as blue water.
In common usage, it is usually used specifically for terrestrial (inland) waterbodies, the vast majority of which is produced by precipitation and runoff from nearby higher areas.
In earth science, erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited.
