Conceptual model for the Bruchsal geothermal site: Fracture-dominated radionuclide transport within the reservoir section in consideration of the physico-chemical water–rock interactions (adsorption–desorption, dissolution–precipitation, alpha-recoil) which take place to varying extent in both, the fracture and matrix element (figure extended after Tricca et al. 2000)
