n. a system of watercourses or drains for carrying off excess water
Wikipedia
An agricultural drainage system is a system by which water is drained on or in the soil to enhance agricultural production of crops. It may involve any combination of stormwater control, erosion control, and watertable control.
In geomorphology, drainage systems, also known as river systems, are the patterns formed by the streams, rivers, and lakes in a particular drainage basin. They are governed by the topography of the land, whether a particular region is dominated by hard or soft rocks, and the gradient of the land. Geomorphologists and hydrologists often view streams as being part of drainage basins. A drainage basin is the topographic region from which a stream receives runoff, throughflow, and groundwater flow. The number, size, and shape of the drainage basins found in an area vary and the larger the topographic map, the more information on the drainage basin is available.
Drainage system may refer to:
- A drainage system (geomorphology), the pattern formed by the streams, rivers, and lakes in a particular drainage basin.
- A drainage system (agriculture), an intervention to control waterlogging aiming at soil improvement for agricultural production.
- A drainage system in urban and industrial areas, a facility to dispose of liquid waste. See Sustainable urban drainage systems and Sewerage.
