Cel To understand the impact of changes in the quantity and qualityof infiltrating water under changed climate conditions ongroundwater resources in the most sensitive European aquifers.As they typically combine high permeability with low storativity,carbonate aquifers are the most sensitive of the major aquifertypes to changes in recharge rate. Furthermore, carbonates areapt to gain or lose porosity in response to changes of pCO2 andtemperature of infiltrating waters. Climate change effects willtherefore be assessed by numerical modelling of coupled flow andnonequilibrium carbonate dissolution/precipitation indual-porosity carbonate aquifer systems. Prediction of possiblechanges in aquifer geometries, hydraulic parameters (permeabilityand storage coefficients), flows/water balance and water qualityunder possible future climate conditions will be undertaken forcarbonate aquifers in three climatic zones (mediterranean,continental, northern maritime).Software for simulation of coupled flow and quality evolutionwill be developed by integrating an existing code for flow indouble porosity aquifers (DP-MODFLOW) with new code representingstate-of-the-art knowledge of carbonate dissolution/precipitationkinetics. At the same time, data describing flow andhydrogeochemistry of major carbonate aquifers representative ofthree different European climatic zones will be assembled.The selected aquifers are the East Yorkshire Chalk, UK (a mature,diffuse flow fluviokarst in the temperate maritime zone); theSwabian Alb karst, Germany (a holokarst developed in gentlydipping Jurassic limestones, representing the temperatecontinental zone); the coastal carbonate aquifers of Mallorca andCatalonia, Spain (which are tectonized and karstified, andrepresent the mediterranean zone). All three aquifers areextensively used for public supply and are among the mostimportant aquifers in Europe.The newly-integrated software willbe tested for its ability to reproduce modern conditions in thesethree systems. Forecasts will require definition of futureclimate scenarios. The main source of information for definingthese will necessarily be the results of other analyses of futurechanges in rainfall and evapotranspiration. In particular,results from General Circulation Model (GCM) simulations will beobtained from the UK Climate Impacts LINK project (CI-LINK).Future changes in sea-level will also be taken into account.A robust relationship between pCO2 and temperature in theatmosphere and corresponding values in recharge waters will bedeveloped to aid in defining the quality of future rechargewaters. Forecasting of future flows and groundwater quality inthe three study systems under these scenarios will then beundertaken, and inter-comparison of results will allowelucidation of the influence of differences in location andgeological framework.
