SE1: Preventing the brownification of water

The Bolmen lake in Southern Sweden is the primary water source for more than 500.000 people. Brownification of lake water is a major problem for the drinking water supply and the biodiversity in Bolmen and other lakes. By creating more and bigger riparian zones, avoiding direct draining into the lake and ensuring a better forest draining water management, the influx of dissolved organic matter can be decreased significantly.

We want to investigate the most effective design of such zones and the impact from different tree species on the organic matter entry into the groundwater to combine both in a conceptual model of the complex hydrological system.
