Groundwater resources of the Pyrenees in the global change context -The PIRAGUA Project

Abstract : The Pyrenees range is a transboundary region shared by Spain, France and Andorre whose water resources are diverse (snowmelt and rainfall runoff in a topographically variable context, groundwater in complex and heterogeneous aquifers) and poorly known. As many other mountain regions, this territory is particularly vulnerable to the impacts of climate change. The PIRAGUA project, funded by FEDER through the EU POCTEFA Program, addresses the assessment of the hydrological cycle of the Pyrenees in the context of climate change. The goals of the project are to unify and homogenize the existing information, prospect for future scenarios, develop indicators of change, and propose adaptation strategies in relation with the territory, with the ultimate goal of supporting investment aimed at adapting to climate change in relation to water resources. In the PIRAGUA framework, the groundwater component of the hydrological cycle of the Pyrenees range is being assessed with focuses on: 1) the design of an homogenous hydrogeological database at the Pyrenean scale, 2) the groundwater recharge from precipitation estimation over the last 30 years (including comparison with different modelling methods) and 3) future recharge evolution according to climate projections downscaled on the Pyrenean scale.
