Groundwater flow and reactive solute transport models in fractured granites: case study in the Äspö island system (Sweden)

The large availability of hydrochemical information at the Äspö site (Sweden) provides a unique opportunity to test numerical models of coupled water flow and reactive solute transport. This paper illustrates the potential of such models for integrating quantitatively hydrody-namic and hydrochemical data using CORE^2D a code developed at University of La Coruña. The impact of the construction of a tunnel on the hydrogeology, hydrochemistry and redox conditions of a deep granitic formation has been evaluated numerically.
