  2. Tile drainage - Wikipedia

    en.wikipedia.org/wiki/Tile_drainage

    The ancient Roman authors Cato the Elder and Pliny the Elder described tile drainage systems in 200 BC and the first century AD, respectively. According to the Johnston Farm, [11] tile drainage was first introduced to the United States in 1838, when John Johnston used the practice from his native Scotland on his new farm in Seneca County, New York.

    en.wikipedia.org/wiki/Drainage_system_(agriculture)

    The checked surface drainage systems consist of check gates placed in the embankments surrounding flat basins, such as those used for rice fields in flat lands. These fields are usually submerged and only need to be drained on certain occasions (e.g., at harvest time). Checked surface drainage systems are also found in terraced lands used for ...

    en.wikipedia.org/wiki/Watertable_control

    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 ...

  8. Drainage - Wikipedia

    en.wikipedia.org/wiki/Drainage

    Drainage is the natural or artificial removal of a surface's water and sub-surface water from an area with excess water. The internal drainage of most agricultural soils can prevent severe waterlogging (anaerobic conditions that harm root growth), but many soils need artificial drainage to improve production or to manage water supplies.

  9. Drainage equation - Wikipedia

    en.wikipedia.org/wiki/Drainage_equation

    the design drain spacing (L) can be found from the equation in dependence of the drain depth (Dd) and drain radius (r). Drainage criteria One would not want the water table to be too shallow to avoid crop yield depression nor too deep to avoid drought conditions. This is a subject of drainage research.
