Catchment restoration

Better methods are needed for restoring streams and lakes affected by nutrient and sediment loading from forestry and other land uses. The current research is carried out on I) developing methods to treat runoff waters from forestry and peatland drainage, II) studies of sediment erosion and transport, III) studies on nutrient emission, IV) studies on stream restoration with different structures, and V) studies on peak flow retention methods to reduce negative impact of drainage.

Current projects:

• Management of forestry drained catchments: Effects of Runoff Water Retention on Erosion, Flood Risks and Water Quality
• Study of flow and sediment transport through measurements and 2D modeling for river restoration planning

• Sediment transport and flow retention in stream restoration
