an area separated from adjacent basins by a divide or ridge
an area that drains all precipitation received as a runoff or base flow (groundwater sources) into a particular river or set of rivers
a portion of the Earth's surface that contains a main stream and its tributaries and is bounded by a drainage divide
A part of the surface of the lithosphere that is occupied by a drainage system or contributes water to a master stream. Drainage basisns of master streams may contain many minor drainage basins.
Landform. A region of land surrounded by ridges and drained by streams that eventually converge to one stream.
the land area from which surface runoff drains into a stream or lake
A part of a land area enclosed by a topographic divide from which direct surface runoff from precipitation normally drains by gravity into a receiving water. Also referred to as a watershed, river basin, or hydrologic unit.
All the land that serves as a drainage for a specific stream or river.
The area of land, surrounded by divides, that provides runoff to a fluvial network that converges to a single channel or lake at the outlet.
the tract of land (both surface and sub-surface) drained by a river and its tributaries.
Total land area that drains to a lake or pond.
region surrounding a lake, reservoir and rivers from which water is drained into
The area of land from which water drains into a river, for example, the Sacramento River Basin, in which all land area drains into the Sacramento River. Also called catchment area, watershed, or river basin.
The land zone that contributes water to the runoff past a given point on a stream.
The land area drained by a stream.
The land area drained by a river.
The total area enclosed by a divide that is drained by a stream network
The portion of the surface of the Earth that contributes water to a stream through overland runoff, including tributaries and impoundments.
area of the earth's surface from which surface drainage all flows to a single outlet stream (a watershed in North America).
a large watershed usually referring to the combination of several watersheds.
all of the area drained by a river system
An area bounded by a drainage divide that gathers water originating as precipitation and contributes it to a particular stream channel or system of channels, or to a lake, reservoir, or other body of water. A drainage basin can be small, such as one that contributes water to a small pond, or large, such as the one that contributes water to the Wabash River. Modified from Glossary of Geology, 4th Edition, 1997, American Geological Institute. See: drainage divide
the watershed area that catches precipitation and drains it over or below the earth's surface to a specific water body
is a part of the surface of the earth that is occupied by a drainage system, which consists of a surface stream or a body of impounded surface water together with all tributary surface streams and bodies of impounded surface water.
The part of the surface of the Earth that is occupied by a drainage system with a common outlet for its surface runoff, consisting of a surface stream or a body of impounded water with all tributary surface streams and bodies of impounded water.
The land that surrounds a body of water and contributes fresh water, either from streams, groundwater, or surface runoff, to that body of water.
A small stormwater drainage area. Also known as a watershed.
A geographical area which contributes surface water runoff to a particular point. The terms "drainage basin," "tributary area," and "watershed" can be used interchangeably.
watershed or catchment.
a watershed; the land area where precipitation runs into streams, rivers, lakes, and reservoirs. It can be identified by tracing a line along the highest elevations, often a ridge, between two areas on a map.
A large watershed encompassing the watersheds of many smaller rivers and streams and draining to a major river, estuary, or lake.
area that contributes surface water to a particular stream system.
The total area drained by a stream and its tributaries. Drainage area, determined planimetrically from topographic maps, is expressed in square miles or square kilometers.
A large area draining to the base of a catchment.
land area where precipitation runs off into streams , rivers, lakes, and reservoirs. It is a land feature that can be identified by tracing a line along the highest elevations between two areas on a map, often a ridge. Large drainage basins, like the area that drains into the Mississippi River contain thousands of smaller drainage basins. Also called a "watershed."
The total land area that drains toward the lake.
The area drained by a stream or river.
Hydrologic unit consisting of a part of the surface of the earth covered by a drainage system made up of a surface stream or body of impounded surface water plus all tributaries. The runoff in a drainage basin is distinct from that of adjacent areas. A river basin is similarly defined.
An area from which water drains to a particular location such as a main river system, a lake, or a sea.
the area from which water drains off the land into a specific body of water (lake, stream)
the area drained, through a valley system, by a river and its tributaries.
The area from which a stream and its tributaries receive their water. A hydrologic unit of area consisting of a surface stream or body of impounded surface water and all its tributaries. Runoff in a drainage basin is distinct from that of adjacent areas.
the area drained by a stream and its tributaries. [AHDOS
A region of land surrounded by divides and crossed by streams that funnel all its water into the network of streams draining the area, usuually to converge eventually to one river or lake.
The area of land that drains water, sediment, and dissolved materials to a common outlet at some point along a stream channel.
A drainage basin is a region of land where water from rain or snowmelt drains downhill into a body of water, such as a river, lake, dam, estuary, wetland, sea or ocean. The drainage basin includes both the streams and rivers that convey the water as well as the land surfaces from which water drains into those channels. The drainage basin acts like a funnel - collecting all the water within the area covered by the basin and channeling it into a waterway.
