NORWAY

The research site in Norway is represented by Bergen, Norway’s second largest city with 270.000 inhabitants. The site is known for high annual rainfalls. However, the changes in precipitation intensity, volume and distribution over the year, warmer winters and less snow fall are causing alterations in run-off distribution and in the water quality characteristics.

The Bergen area has a range of mountains that lead to significant local variations in rainfall patterns. Bergen faces seasonal water scarcity problems, as in 2010 after a cold winter without rain/snow lasting from December to April. A method for forecasting available water resources from short-term to mid-term (10 years) would be of substantial benefit.

Water quality is periodically influenced by high values of natural organic matters (NOM), which is expected to increase due to climate changes. Wastewater is treated by high-grade treatment plants, discharging the water to vulnerable recipients. Extensive flash floods from hillsides are collected at the city centre infrastructure, mixed with wastewater and transported to the wastewater treatment plants partly via combined system with several Combined Sewer Overflows (CSOs).

Discharge from CSOs and the treatment plants can thus have a significant impact on the water quality of the receiving bodies and threaten bathing water quality. The impact of climate change to this situation will be studied.
