American Geophysical Union - AGU Fall Meeting 2016

#1- American Geophysical Union - AGU Fall Meeting 2016

Le Laboratoire M2C organise en 2016 2 sessions à l’AGU Fall meeting qui se déroulera à San Francisco (USA) du 12 au 16 décembre 2016 :

## Session H018 : Characterization, Modeling, and Remediation of Fissured, Carbonate, and Karst Groundwater Systems

Fractures, conduits and surface solution features in carbonate karst systems lead to strong surface/subsurface interactions that result in significant water, mass, energy, and contaminant transport within the critical zone. These systems are dynamic and highly heterogeneous, with complex hydrologic, geochemical, and biological processes occurring over a wide-range of spatio-temporal scales. As a result, these systems show non-linear responses and are extremely difficult to characterize, model, remediate, and manage. Particular challenges arise from lack of knowledge and technologies needed to integrate heterogeneous processes and pathways across the surface, vadose, and saturated zones, to address the hydrologic and biogeochemical responses of these systems to short- and long-term climate change, and to improve and develop the most appropriate remediation approaches. This session requests abstracts on research related to multi-scale variability, characterization, monitoring, modeling, and remediation of fissured, carbonate, and karst water systems.

## Session H065 : Large-scale climate variability and its impact on hydrological systems, water resources and population

Hydrological systems are very sensitive to changes in climate. Recent and future increased temperatures are expected to increase potential evapotranspiration and possible complex changes in rainfall variability, which can impact on soil moisture, streamflow, groundwater recharge, floods and droughts. Such hydrological impacts can be assessed by forcing hydrological models with simulations from downscaled global climate models. However, hydrological systems are also influenced by modes of climate variability (ENSO, NAO, AMO), whose the continental impacts are not well reproduced in global climate models. This reduces significantly our capacity to project future changes in hydrological systems and water resources, and to develop adaptation scenarios for population.
We therefore welcome abstracts which capture recent insights for understanding past or future impacts of large-scale climate variability on hydrological systems, including projections and reconstructions, as well as impact or adaptation scenarios for water resources. Results from model intercomparison studies are especially encouraged.
