BEVIS I - II

A joint decision support system for effective water protection measures in the archipelagos of Turku, Åland, and Stockholm

Joint protective measures for water quality were created in a multinational study for the three archipelago areas of Turku, Åland and Stockholm. Effective protection plans are needed to achieve a good ecological status of EU waters by year 2015 as stated by the EU Water Framework Directive.

Project deliverables

BEVIS phase I (2004-2006)

• a joint database with nutrient loading data from diffuse and point sources, and monitoring data of water quality measurements in the project area 1
• two different high resolution 3-D water quality models that describe nutrient concentration and/or the amount of phytoplankton in the project area 1
• model simulations and environmental economic calculations of seven future scenarios for the project area 1
• conclusions of the project results and recommendations for measures

• new estimations of the phosphorus release from the sediments to the overlaying waters in the project area 1
• a mesoscale water quality model for the project area 2 (Svealand coast)
• model simulations and environmental economic calculations of three new future scenarios for the project area 1
