dc.description.abstractWell yields from Precambrian and Palaeozoic bedrock in Norway, Sweden and Finland exhibit very similar and approximately log-normal distributions: all three data sets exhibit a median yield of 600-700 L hr-1, despite the differences in climate and lithology. This similarity is tentatively reflected on a larger geographical scale by a meta-analysis of the international data sets on crystalline rock aquifers from other recently glaciated areas (i.e., without a thick regolith of weathered rock). An heuristic treatment of the Fennoscandian data sets suggests that this median yield is consistent with the following bulk properties of shallow (to c. 70-80 m depth) crystalline bedrock: transmissivity of 0.56 \u00B1 0.30 m2 d-1 (6.4 \u00B1 3.4 x 10-6 m2 s-1) and hydraulic conductivity of around 1.1 (\u00B1 0.6) x 10-7 m s-1.
