To face the threats to the water supply and to maintain sustainable water management policies, detailed knowledge is needed on the surface-to-subsurface transformation link in the water cycle. This title covers recharge flux as well as many other groundwater issues, including approaches to determine groundwater recharge.
Detailed description of interface and phase transition processes
Presents independent methods to determine groundwater recharge
Offers an extended data set from the atmosphere/biosphere/lithosphere to the groundwater surface
