The Kokemaenjoki River Basin is the fourth largest in Finland. The city of Pori at the delta of the river is the most significant flood risk area in Finland. The preparation of a flood risk management plan (FRMP) for the Kokemaenjoki River Basin as a national pilot began in 2007 and will be finalised during 2011. The main challenges of the FRMP are the reconciliation of flood risks and various interests in different parts of the river basin, and adaptation to climate change. It has been predicted that climate change will alter the flood dynamics of the Kokemaenjoki River: the highest flow peaks will shift from spring to late autumn and winter and the risk of ice jam floods will increase. Development of the existing early warning systems and adaptive lake regulation practices are the two most important non-structural measures for preventing and mitigating flood damage. A new channel in the mid-river reach would help to manage the increasing winter flows. Also robust structural flood protection measures will be needed in the city of Pori. Nevertheless, close collaboration among authorities, municipalities and water body regulators will be critical in successful flood risk management in the Kokemaenjoki River Basin.
