The modeled values for the TSS fluctuated from 0.1 to 61 kg/ha for the
Smugawka catchment (Fig. 4) and from 0 to 580 kg/ha for the Mszanka
catchment (Fig. 5). Notably, the Smugawka (Fig. 4) and Mszanka (Fig. 5)
microcatchments are mainly characterized by river flow. This is
particularly evident in sections with large slopes in the upper part of
the microcatchments. In the main drainage watercourse, the
modeled P-PO43- values ranged from 20
to 23 kg/ha in the Smugawka stream (Fig. 6) and from 125 to 149 kg/ha in
the Mszanka stream (Fig. 7).
