Some Characteristics of the Vansjø-Hobøl (Morsa) Catchment
Abstract
This report gives an overview of some characteristics of the Vansjø-Hobøl (Morsa) catchment in Southern Norway. The catchment is one of the most studied catchments in Norway in terms of water quality, partly because it has been a pilot project for the implementation of the EU Water Framework Directive (WFD), partly because eutrophication and harmful algal blooms have been a problem in the latter years. Information from the catchment has until now been scattered in several different papers and reports, and most of these have been written in Norwegian.
