Stream flow data were modelled for two catchments that are included in the Swedish Swedish Meteorological and Hydrological Institute's (SMHI) catchment database for which their S-HYPPE model produces daily flow data. Model outputs were compared to pressure data (transducers XX model etc).   \subsection*{Catchment delineation and peatland cover}  The catchments of the sampled streams were produced in ArcGIS 10.3, software from ESRI, using a national elevation model from Lantmäteriet (2015a) that had a resolution of 2x2 m and accuracy of 0.5 m. When rain hits the surface it will run in the steepest slope direction which is determined in the elevation model. By grouping the surfaces of the steepest slopes with the same direction watersheds were delineated. Catchment delineation was visaully quality checked to ensure high accuracy of the delineation process.  Peatland cover for each catchment was estimated from the Swedish soil layer raster (The Geological Survey of Sweden, SGU). \subsection*{Analyses}  sasa
