| Abstract: | This paper presents a formula for computation of time-varying recharge of groundwater. The formula is derived from the basic equation of groundwater flow on an inclined impervious base. This analytical expression can also be used to compute evaporation rate if there is no recharge of groundwater. Readings from electronic data loggers show that recharge of groundwater is highly variable depending on the patterns of rainfall and antecedent conditions of the soil. |
