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 ...
Water table. Cross-section of a hillslope depicting the vadose zone, capillary fringe, water table, and the phreatic or saturated zone. (Source: United States Geological Survey .) The water table is the upper surface of the zone of saturation. The zone of saturation is where the pores and fractures of the ground are saturated with groundwater ...
Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface.
Drainage system (agriculture) 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 .
A site plan is a "set of construction drawings that a builder or contractor uses to make improvements to a property. Counties can use the site plan to verify that development codes are being met and as a historical resource. Site plans are often prepared by a design consultant who must be either a licensed engineer, architect, landscape ...
A drainage equation is an equation describing the relation between depth and spacing of parallel subsurface drains, depth of the watertable, depth and hydraulic conductivity of the soils. It is used in drainage design. Parameters in Hooghoudt's drainage equation. A well known steady-state drainage equation is the Hooghoudt drain spacing equation.
The Brihanmumbai Stormwater Disposal System is a project planned to overhaul Mumbai 's water drainage system. The estimated budget for implementing the project is Rs. 12 billion (approx. 300 million US dollars) as of August 2005. Such a high-budget project would require funds from the Central Government. Mumbai has a drainage system, which in ...
Vertical drainage systems are drainage systems using pumped wells, either open dug wells or tube wells. Map of a well field for subsurface drainage with radial flow across concentrical cylinders representing the equipotentials. Both systems serve the same purposes, namely water table control and soil salinity control.
