Summary
In the Norwegian River Monitoring Programme (in Norwegian: Elveovervåkingsprogrammet) 20 rivers along the Norwegian coastline are monitored for chemical and hydrological parameters. It is a continuation of the RID programme (Riverine inputs and direct discharges to Norwegian coastal waters) that started in 1990. This report presents the current status (2020) and long-term (1990-2020) water quality trends.
