Project summary

Edit project overview to modify the project summary.


The Lussebäcken brook is tributary of River Råån and it´s situated in Southern part of Sweden in the city of Helsingborg. The drainage area of the brook is mostly agricultural, cultivated land. Before restoration the brook had few serious problems which caused flooding problems and rinse of sediment and nutrients from the fields. The brook was very deep and slope of the bank steep which caused serious erosion problems. To prevent the flooding and erosion two-stage drainage channel was constructed. The object was to stabilize the stream by decreasind the slope of the banks, creating riparian zones and increasing meandering in the stream. Also stones and gravel were added in the bed of the stream to create more natural habitat for fish and other aquatic organisms. The restoration took place in 2002 and it was managed by the municipality of Helsingborg.
