Parameters of horizontal drainage Parameters of vertical drainage. The subsurface field drainage systems consist of horizontal or slightly sloping channels made in the soil; they can be open ditches, trenches, filled with brushwood and a soil cap, filled with stones and a soil cap, buried pipe drains, tile drains, or mole drains, but they can ...
Subsurface drainage: Built by burying pipes underground to remove excess water from the soil profile. Subsurface drainage is widely used by farmers. It has many advantages: [5] It increases soil humidity and leads to better crop yields. It stops the accumulation of salts and gives farmers more flexibility to plant different types of crops.
Israeli Netafim, drip irrigation. Drip irrigation or trickle irrigation is a type of micro-irrigation system that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants, either from above the soil surface or buried below the surface.
Subsurface (groundwater) drainage for water table and soil salinity in agricultural land can be done by horizontal and vertical drainage systems. Horizontal drainage systems are drainage systems using open ditches or buried pipe drains. Vertical drainage systems are drainage systems using pumped wells, either open dug wells or tube wells.
While this is a lesser issue for surface irrigation compared to other irrigation methods (due to the comparatively high leaching fraction), lack of subsurface drainage may restrict the leaching of salts from the soil. This can be remedied by drainage and soil salinity control through flushing.
Irrigation (also referred to as watering of plants) is the practice of applying controlled amounts of water to land to help grow crops, landscape plants, and lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world.
Agricultural land drainage has agricultural, environmental, hydrological, engineering, economical, social and socio-political aspects (Figure 1). All these aspects can be subject of drainage research. The aim (objective, target) of agricultural land drainage is the optimized agricultural production related to: reclamation of agricultural land
In the same fashion, the well drainage requirement can be found from well discharge (Wel) in the geohydrologic water balance or the overall water balance. The subsurface drainage requirement and well drainage requirement play an important role in the design of agricultural drainage systems (references:, [4] [5]).
