PREFACE This is the fifth Nordic Hydrological Conference being hosted in Iceland, with the last one being in Akureyri in 1996. The conference is being held by the Nordic Association for Hydrology (NHF), which is an independent body aiming at promoting hydrology as a science and at increasing the understanding of hydrology and of hydrological methods within applied sciences and water planning in the North. NHF membership is open to all individuals and institutions/companies actively interested in hydrological work or research. The purpose of the conference is to share experience in different fields of hydrological research and practice, and improving management of water resources. The conference will last three days and revolve around several themes with poster and oral presentations followed by discussions. Themes: - Advanced Methods and Technologies in Hydrological Practice - Agriculture, Forestry and water, Land-use changes - Arctic Hydrology and Glaciers - Eco-Hydrology in regulated rivers and streams - Climate and Energy Systems (CES special session) - Hydropower and Hydrology - Uncertainty and Extremes in Hydrology - Water Quality - Water Resources Management under Climatic Change The Conference is being organized by the National Power Company (NPC) and the Hydrological Service (HS) on behalf of NHF in cooperation with the Icelandic Hydrological Committee (IHC) and the University of Iceland (UI). The Organizing Committee is chaired by Óli Grétar Blöndal Sveinsson (NPC) and composed of Árni Snorrason and Jórunn Harðardóttir (HS), and Kristinn Einarsson (IHC). The Scientific Advisory Committee is co-chaired by Sigurður Magnús Garðarsson and Hrund Ólöf Andradóttir (Iceland) and composed of Jens Christian Reefsgard (Denmark), Bjørn Kløve (Finland), Agrita Briede and Elga Apsite (Latvia), Arvydas Povilaitis (Lithuania), Ingjerd Haddeland (Norway), and Gia Destouni (Sweden). Any opinions, conclusions and recommendations expressed in these proceedings are those of the authors and do not necessarily reflect the views of the members of the Scientific Advisory Committee or the editors. The organizers wish to thank those who helped make the conference possible and all the authors for their contribution. 9
