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 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.
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).
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.
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.
(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.
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.
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 ability of a geotextile to collect and transport fluids. Liquids or gases are transmitted within the plane of the geotextile and this involves flow across the geotextile. For example, geotextiles are used to capture and transmit gases (eg methane) beneath the geomembrane in a landfill capping system.
The migration of oil or gas in a reservoir toward a wellbore due to pressure reduction caused by production of reservoir fluids by the well. A drainage point is a wellbore (or in some cases several wellbores) which drains the reservoir.
Drainage is used to represent major field works where large channels are cut across fields and infilled with stones to aid the drainage of the land. Often fulachta fiadh are the victims of such works, and their stone used to line the newly dug channels.
Conduction of electric current from an underground metallic structure by means of a metallic conductor. Forced drainage is that applied to underground metallic structures by means of an applied electromotive force or sacrificial anode. Natural drainage is that from an underground structure to a more negative (more anodic) structure, such as the negative bus of a trolley substation.
