The Javngyde catchment is located in the central part of the Jutland peninsula in Denmark. It is a relatively small catchment with a size of app. 10.5 km2. The landscape and the subsurface is dominated by previous glacial activities, resulting in a highly variable topography, and most likely a similar complex subsurface.
The agricultural area constitutes app. 79% of the catchment. The streamflow has been monitored for 25 years with 24 years of nitrogen and phosphorus measurements.
Based on the existing information from geophysical data and lithological logs, combined with information from the local farmers in the area, it is expected that the subsurface is highly heterogeneous. In some sub-parts it is therefore also expected that sand layers will reach the surface, while other areas will have clay sediments near terrain.
