Results from artificial recharge tests through wells in Angered, Gothenburg have made studies on geohydrological properties of tectonic zones possible. Measurements of piezometric head in bore holes were used to evaluate the transmissivity and storage coefficient of the zones by using a finite element model. The zones were considered to act as separate confined aquifers, and the values obtained were T ≡ 3-4 · 10−6 m2/s and S ≡ 4-6 · 10−5.. The hydraulic conductivity of the rock mass was then found to be greater than 2-5 · 10−8 m/s, which is in agreement with values of fractured, crystalline rock in Sweden obtained in other investigations.
