1. 1 Water discharge rate is monitored continually

2. 2 Sampling of stream and drainage water is made automatically or by grab sampling weekly while groundwater is sampled 6 times/year. Water samples are analysed for pH, conductivity, nutrients (N & P), organic carbon and suspended material. In addition, water is analysed for major constituents (K, Na, etc.) in the agricultural fields and in some of the catchments. Analyses for pesticides are made in four catchments. Transport calculations are made by using daily concentration values, derived by linear interpolation of the weekly measured values, and daily discharge rates.

3. 3 Crop management is registered yearly for the agricultural fields programme and for the fields within the catchments. Registrations are also made of changes made within the catchments affecting point sources.
