Population growth, agriculture expansion, climate change and unsustainable water use have resulted in the degradation of groundwater availability and quality and groundwater-dependent ecosystems. While urgently needed, regional strategies for groundwater sustainability have been challenged by the complex nature of groundwater systems, which depend on multi-scale heterogeneous topography and geology, fluctuating climate, changing land use and anthropogenic forcing. Disentangling this complexity and developing adequate modeling frameworks in support of decision making is important to sustain our present and future needs in groundwater while preserving ecosystems.
This session seeks contributions that (i) unravel the combined action of topography, geology, climate, land use and anthropogenic forcing in controlling regional groundwater availability, quality and sustainability; and (ii) propose new methods (e.g., coupled modeling approaches) for assessing and managing regional groundwater systems in diverse climatic, hydrologic, social and political settings, and accounting for uncertainty.
