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 ] ).
A drainage system influences this depth; the relation between drainage system design and depth of water table is mainly physical and can be described by drainage equations, in which the drainage requirements are to be found from a water balance. [1] The depth of the water table as a criterion factor needs to be translated into a criterion index ...
The report A Comprehensive Assessment of Water Management in Agriculture [1] was published in 2007 by International Water Management Institute and Earthscan in an attempt to answer the question: how can water in agriculture be developed and managed to help end poverty and hunger, ensure environmentally sustainable practices, and find the right balance between food and environmental security?
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 ...
The law of water balance states that the inflows to any water system or area is equal to its outflows plus change in storage during a time interval. [ 2 ] [ 3 ] In hydrology , a water balance equation can be used to describe the flow of water in and out of a system.
Farm water, also known as agricultural water, is water committed for use in the production of food and fibre and collecting for further resources. In the US, some 80% of the fresh water withdrawn from rivers and groundwater is used to produce food and other agricultural products. [ 1 ]
The World Bank Group is the globe’s most prestigious development lender, bankrolling hundreds of government projects each year in pursuit of its high-minded mission: to combat the scourge of poverty by backing new transit systems, power plants, dams and other projects it believes will help boost the fortunes of poor people.

The water balance is enhanced; Crops do not suffer later on from water shortage, Fertile soil particles are not lost by water and wind erosion. When the sun shines on the water, light and heat are reflected onto plants on the northern shore of the trench, this effect and the increased humidity create micro climates in the area.
