Amongst the number of methods available for calculating groundwater recharge, the, hydrodynamic method is reliable as it takes into consideration the changes in water level, which is a true picture of groundwater regime of the area.

Groundwater recharge is first calculated by multiplying the specific yield obtained by pump test with the actual rise of water level in the well for a given period. From this daily recharge is calculated, which is expressed as a percentage of rainfall.
