-In wetlands, retention of inorganic nitrogen is modelled (denitrification). For total phosphorus retention (sedimentation) and production (or release from sediments) of TP are modelled. The rates of these processes are constant coefficients (//​teta//​=1.2,​ //​tkoeff//​=20,​ //​inpar//​=2.3,​ //sedpar//= 0.09, and //​uptpar=//​0.1). The retention is limited to 99.9% of the substance in the wetland. The retention (//retIN, retTP, g/d//) depends on the rate parameter, the concentration in the wetland, wetland area, and for inorganic nitrogen also on 5-day-mean temperature. The production (//prodTP, g/d//) depends on a rate parameter, the concentration of the inflow to the wetland, wetland area, and a temperature function. ​+In wetlands, retention of inorganic nitrogen is modelled (denitrification).
