A draining; a gradual flowing off of any liquid; also, that which flows out of a drain.
The mode in which the waters of a country pass off by its streams and rivers.
The system of drains and their operation, by which superfluous water is removed from towns, railway beds, mines, and other works.
Area or district drained; as, the drainage of the Po, the Thames, etc.
A essential ingredient in planting roses. While all roses need adequate water, few will thrive if water congregates around their roots. Soils with high clay content should be heavily amended to provide drainage.
the interception and/or removal of surface and/or groundwater from a given area by natural or artificial means
relates to the flow of water. Good drainage in soil keeps a plant's roots from drowning. Managed drainage built into a landscape can direct rain water to help irrigate plants.
In cartography, all features on a map associated with water, for example, rivers, lakes, shoreline or marshes.
a system designed to remove water from a structure
Movement of water away from the surface of a garden either down into the soil or by flow across the surface.
Formation of a paper or board web on the wire by removing water at the paper machine wet end
an area through which run-off water drains; usually lower than surrounding areas.
Runoff of excess water from an area.
the passing-speed of water through soil.
the removal of surface water from within a specific area
manner by which waters of an area flow off in surface streams.
The run-off in a drainage area. A system of piping to carry off water.
A water source, such as a stream.
way to empty soil of excess water: with good drainage, water passes through soil evenly, promoting plant growth; with bad drainage water stands in soil, drowning roots.
An area where water flows. In the dry Southwest, a drainage may have water only after a summer rainstorm or during the spring, when melting snow produces a lot of water.
a system of drains and pipes for carrying away surface water. An asphalt surface is sloped to maximize the removal of surface water for vehicular safety. E - F - G
Natural channel through which water flows or may flow during a period of the year.
The routes followed by water on site as they flow off, pond on, or drain into the ground surface.
The movement of water across a piece of property. Drainage is divided into two basic types: surface drainage, which is visible and above the ground or on top of surfaces such as a roof, patio, or drive; and subsurface drainage, which occurs below ground.
act, process or means of removing excess water from the surface Return to Previous Page.
1) A watershed, or 2) The ability of a substance to pass water through it. Gravel has good drainage, while clay has poor drainage.
Natural or artificial means for the interception and removal of surface or subsurface water.
The process of transporting surface water over a land area to a river, lake or ocean (surface drainage), or removal of water from a soil using buried pipelines that are regularly spaced and perforated (subsurface drainage).
This is a system of drain pipes and gutters that work together to filter water away from the foundation of the house. This prevents water from causing erosion around your home.
Any channel that carries water.
The removal of excess water from the land surface and/or from the soil profile. Surface Drainage The diversion or orderly removal of excess water from the surface of the land by means of improved natural or constructed channels, supplemented when necessary by the sloping and grading of land surfaces to these channels. Subsurface Drainage The removal of excess water from the soil profile by means of drain tiles, perforated pipes, or other devices.
All of the waters comprising a watershed, including tributary rivers, streams, sloughs, ponds and lakes that contribute to the water supply of the watershed.
A network of streams transporting water and eroded sediment from a landscape
The sheet water flow and ability of a site to divert and drain excess water.
An area (basin) mostly bounded by ridges or other similar topographic features, encompassing part, most, or all of a watershed and enclosing some 5,000 acres.
The movement of water through the soil. With good drainage, water disappears from a planting hole in less than a few hours. If water remains standing overnight, drainage is poor.
The removal of excess surface water or groundwater from land by means of ditches, or subsurface drains.Drainage Area. The area draining into a stream at a given point. It may be of different sizes for surface runoff, subsurface flow and base flow, but generally the surface runoff area is considered as the drainage area.
(soil) The rapidity and extent of the removal of water from the soil by surface runoff and by down-draw flow through the soil. Also, the natural and artificial means for improving this removal by a system of surface and subsurface conduits.
a drain or a system to draw off, the slope around a building, the ability to remove water from a surface or a designated area of property
Natural channel through which water flows some time of the year. Natural and artificial means for effecting discharge of water as by a system of surface and subsurface passages.
The process of removing surplus ground or surface water either by artificial means or by gravity flow.
(1) The process of removing surplus ground or surface water by artificial means. (2) The system by which the waters of an area are removed. (3) The area from which waters are drained; a drainage basin.
A system of gutters and drainpipes that carry water away from the foundation of a house.
The rapid removal of water by surface contouring (swales or ditches) or the installation of subsurface tile.
Loss of water from soils, either by percolation through the soil or by surface flow across the soil. Adequate drainage is necessary for good soil aeration, but soils that drain too well have low soil water content and may dry too quickly for good crop growth without irrigation.
basin see watershed.
Drainage is the act or process of draining, a system of drains, if 'al or natural. Interception and removal of surface or groundwater. Conveyance of unwanted water from one point to another.
A technique to improve the productivity of some agricultural land by removing excess water from the soil; surface drainage is accomplished with open ditches; subsurface drainage uses porous conduits (drain tile) buried beneath the soil surface.
The system of gutter and drainpipes used to carry water away from the foundation of a home.
Surface water runoff; the removal of surface water or groundwater from land by drains, grading or other means which include runoff controls.
Improving the productivity of agricultural land by removing excess water from the soil by such means as ditches or subsurface drainage tiles.
Drainage is the natural or artificial removal of surface and sub-surface water from a given area. Many agricultural soils need drainage to improve production or to manage water supplies.
