1. 1. Water supply in hard rock coastal regions : The effect of heterogeneity and kinematic porosity

   Författare :Robert Earon; Bo Olofsson; Gerhard Barmen; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coastal aquifer; Crystalline rock; Water balance; Geographic information systems; Water supply planning;

   Sammanfattning : Water resources in hard rock terrain are difficult to characterize due to heterogeneity and anisotropy in the fracture network, low porosities and limited recharge volumes available during the summer season. Three methods were developed and evaluated in order to assist in water supply planning. LÄS MER
