The estimation of groundwater recharge from spring hydrographs

The amount of groundwater recharge to an aquifer depends on the amount of precipitation and its seasonal distribution, the air temperature, the land use, and other factors; direct measurements of the recharge components are not possible. Because of these factors, determining the recharge to aquifers is a difficult problem in all water resource studies. A project for determining quantitative groundwater recharge is illustrated by the computation of the groundwater balance of the Kirkgöz springs area in the Mediterranean region of Turkey.
