13 Artificial and natural groundwater recharge (co-organized by IAH)

Donnerstag, 12:00-13:00, HS 1

Recharge of groundwater is a fundamental --- but so far poorly understood --- topic for continental water balances worldwide. When facing droughts and extreme precipitation, its understanding has become increasingly important. For instance, groundwater recharge and storage has the potential to link both extremes in a mitigating manner. On the one hand, we need to improve quantifications of natural groundwater recharge and on the other hand, better technical understanding of its artificial counterpart has the potential to become a viable alternative for surface water storage and cleanup. However, associated consequences of unbalanced groundwater recharge may include undesired effects such as compromised water quality, land subsidence or flooding, insufficient or even overabundant availability of water to plants. We invite contributions from all fields including aqueous geochemistry, groundwater modelling, soil sciences, construction of wells, biological and agricultural influences, ecosystem research as well as investigations on groundwater-surface water interactions. With this we hope to establish new interaction on the topic in an interdisciplinary session on a fundamental issue in hydro(geo)logy.
