Drainage Area - USGS
The term "drainage area" is defined as the land area where precipitation falls off into creeks, streams, rivers, lakes, and reservoirs. It is a land feature that can be identified by tracing a line along the highest elevation between two areas on a map, often a ridge.
Watersheds and Drainage Basins | U.S. Geological Survey - USGS.gov
2019年6月8日 — Ridges and hills that separate two watersheds are called the drainage divide. The watershed consists of surface water --lakes, streams, reservoirs, and wetlands --and all the underlying groundwater. Larger watersheds contain many smaller watersheds.
StreamStats | U.S. Geological Survey - USGS.gov
StreamStats provides access to spatial analytical tools that are useful for water-resources planning and management, and for engineering and design purposes. The map-based user interface can be used to delineate drainage areas, get basin characteristics and estimates of flow statistics, and more.
What Is a Drainage Area? - The Land Development Site
A drainage area is the area of land upon which rainwater falls during a storm event before running downstream along the land. You might also hear drainage areas for larger areas be referred to as drainage basins.
Drainage basin - Wikipedia

Drainage Basin - Education
2024年7月19日 — A watershed is an entire river system —an area drained by a river and its tributaries. It is sometimes called a drainage basin. Watersheds can cover wide areas. Runoff water from a large watershed in the mid continental United States drains into the Gulf of Mexico through the Mississippi River system. The Amazon River watershed is huge ...
Drainage Area - an overview | ScienceDirect Topics
The drainage area involves the thickness and width of a drainage layer. The drainage layer thickness affects the time-to-drain according to the FHWA model while showing insignificant effects on time-to-drain according to LTPP statistical analysis [80,81] .
Drainage | Definition, Agriculture, Importance, Construction, Types ...
Drainage can remove excess water from an area before it enters the soil, and thus it prevents leaching of nutrients and standing pools of water on the surface and can permit early spring planting.

2023年11月21日 — A drainage basin is defined as an area of land where water from precipitation, springs or flow will ultimately end up in a common body of water or common waterway outlet. Drainage basins are...
Glossary: Drainage area - GreenFacts
A drainage area is the total surface area, upstream of a point on a stream, where the water from rain, snowmelt, or irrigation which is not absorbed into the ground flows over the ground surface, back into streams, to finally reach that point.
