River flow (m3 yr-1) for 12 selected hydropower plants in Swedish rivers as well as the total river discharge to the Swedish coast. The dataset include both Naturalised River Flow and Regulated River Flow, in daily time-series from 1981-2010, calculated with the HYPE model code (HYPE_version_4_3_1) in S-HYPE model set-ups (QR: s-hype2012_version_1_2_1 resp. QN: s-hype2012QN_version_1_2_1). Model code can be downloaded from: http://hypecode.smhi.se/ and model results with high spatial resolution can be downloaded from http://vattenwebb.smhi.se/. The results for the whole country of Sweden have been published in: Arheimer, B. and Lindström, G. 2014. Electricity vs Ecosystems – understanding and predicting hydropower impact on Swedish river flow. Evolving Water Resources Systems: Understanding, Predicting and Managing Water–Society Interactions. Proceedings of ICWRS2014, Bologna, Italy, June 2014; IAHS Publ. 364:313-319.

The HYPE model code (HYPE_version_4_3_1) was used in the S-HYPE model set-ups (QR: s-hype2012_version_1_2_1 resp. QN: s-hype2012QN_version_1_2_1) at SMHI.
