Summary
In August 2020 a set of 12 artificial streams was built at Svartberget. The channels are 15 m long and 20 cm wide and are fed with water from the near-by C8 stream. The water is pumped into a 3000 l collection tank to sustain a constant flow (can vary between 0 and 1 l/s in each channel) by using an electric pump. The channels are designed in four triplets, each triplet is fed from a 1000 l manipulation tank and thus 4 levels of water treatments with 3 replicates each can be achieved. The slope of the channels can vary between 0 and 1.5 degrees and temperature can be manipulated due to a local electricity source. The bottom of the channels is covered by gravel and pebbles but can be manipulated (e.g., sand or organic layer aditions). The channels spills out to a forest floor, ensuring filtering water before reaching the C8 stream again. The channels are constructed to last at least 10 years, possibly longer.
