The project REFORMWATER (Reducing the effects of forest management to inland waters) is a joint project between Finland (University of Helsinki and University of Eastern Finland), Estonia (University of Tartu), Ireland (University College Dublin) and Sweden (Swedish University of Agricultural Sciences) funded by European Union Joint Call 2018 - WaterWorks 2017. The project will develop novel methods and protocols for decreasing the effect of forest management operations on aquatic systems and quantifies the effects of forest management operations on water quality. We will also develop supporting tools for sustainable integrative management of water resources .i.e. a model-based tool for reducing the impact of forest management on aquatic systems.
