Roots can survive waterlogging by forming aerenchyma, inducing anaerobic metabolism, and changing root system architecture. [14] In irrigated agricultural land, waterlogging is often accompanied by soil salinity as waterlogged soils prevent leaching of the salts imported by the irrigation water.
Waterlogging or water logging may refer to: Waterlogging (agriculture), saturation of the soil by groundwater sufficient to prevent or hinder agriculture; Waterlogging (archeology), the exclusion of air from an archeological site by groundwater, preserving artifacts; Underwater logging, the process of harvesting trees that are submerged under water
In geotechnical engineering, watertable control is the practice of controlling the height of the water table by drainage.Its main applications are in agricultural land (to improve the crop yield using agricultural drainage systems) and in cities to manage the extensive underground infrastructure that includes the foundations of large buildings, underground transit systems, and extensive ...
Such a system is therefore called a checked, or controlled, drainage system. More usually, however, drainage systems are meant to function as regularly as possible to prevent undue waterlogging at any given time and it is this regular drainage system that is most often employed. In agricultural literature, this is sometimes also called a ...
The drainage system designed to evacuate salty water also lowers the water table. To reduce the cost of the system, the lowering must be reduced to a minimum. The highest permissible level of the water table (or the shallowest permissible depth) depends on the irrigation and agricultural practices and kind of crops.
waterlogging and drainage problems in villages, agricultural lands, and along roads - with mostly negative consequences. The increased level of the water table can lead to reduced agricultural production. shallow water tables - a sign that the aquifer is unable to cope with the groundwater recharge stemming from the deep percolation losses
Drainage system (agriculture), land forming or land shaping to enhance the drainage from the soil surface in agricultural land; Contour plowing, controlling runoff and soil erosion; Subsurface (groundwater) drainage Horizontal drainage by pipes and ditches Tile drainage; Vertical drainage by wells Well drainage; Watertable control; Otherwise:
Tile drainage is a form of agricultural drainage system that removes excess sub-surface water from fields to allow sufficient air space within the soil, proper cultivation, and access by heavy machinery to tend and harvest crops.
