Quantification of percolation from percolation tank
Uncertainty in the occurrence of rainfall with respect to time and quantity is a major contraint to agricultural production in rainfed areas. To alleviate the constraint, groundwater is pumped at an unsustainable rate causing continuous water table decline. Groundwater recharge by the rainwater and runoff harvested in percolation tanks can augment the groundwater resource. A study was conducted to quantify percolation from a percolation tank by using water balance approach.
