Groundwater recharge from run-off, infiltration and percolation

the long version

"This book first addresses the recharge fluxes relating both to the quantity and quality of groundwater. In order to face the threats to the water supply and to be able to maintain a sustainable water management policy, detailed knowledge is needed on the surface-to-subsurface transformation link in the water cycle. Secondly, a comparison of both the traditional and modern approaches to determine groundwater recharge is presented. The traditional approach to determine groundwater recharge is based on water balance estimates and hydraulic considerations, which yield instantaneous values at best but do not integrate the totality of recharge pathways in time and space. In contrast, environmental tracers integrate these factors. Finally, the fate of groundwater recharge in the subsurface by hydraulic and geologic means is explained in detail, in order to stimulate adapted groundwater-management strategies and to better assess consequences of climate changes on groundwater resources as a whole." "This book will be valuable for researchers and scientists in hydrology, hydro-geology, engineering, geography, agronomy, soil science, groundwater modelling, environmental physics and limnology."--Jacket.
