Sammendrag

In Norway, and many other countries, subsurface drainage systems are a necessity to practice agriculture. Drainage systems, through control of the groundwater level, have a direct influence on the soil moisture content. To facilitate tillage practices and harvesting depending on soil type, the soil moisture content has to be at 80 – 90% of the field capacity in the top 20 cm of the soil profile. The main objective was to get information about the half time , i.e. the time required to reduce the runoff to 50% of the runoff at the onset of a recession period. The average half time for the small field scale catchments varied from 6 – 16 hours, indicating a fast drawdown of the water Level. The analysis of subsurface drainage is carried out as part of IRIDA, an EU/JPI funded project.
