Theme VII. Ecology and management on forested peatlands
Ditch network maintenance at peatland forest areas leads to erosion and transport of suspended solids to water courses. The aim of this study is to explore how sediment load is generated within maintained drainage areas. This task is tackled by setting up experiments at Koivupuro catchment, located in Eastern Finland, which has been studied since the initial ditching in 1980s. During the summer of 2011 the ditches in the area were cleaned and a new nested study catchment was established inside the catchment. Both catchment outlets were instrumented with continuous water level and turbidity sensors. Basic hydrological monitoring and different in-situ methods to measure erosion and sediment transport at source areas are also applied and the properties of sediment studied with laboratory analyses.
