3.2. Hydrodynamic appraisal
For both flysch streams, the calculated transport intensity was taken from the part of the catchment used for agriculture. The transverse turbulence diffusion coefficient did not differ. On average, 0.094 m2·s-1 of water was adjacent to arable land in the Mszanka stream, while 0.07 m2·s-1 was partly dominated by grasslands in the Smugawka stream. Water in the streams that were predominantly surrounded by arable land was mixed with hydrochemical indicators after a distance of 50 m (Tables 3 and SX).
