W artykule przedstawiono metodykę opracowania transportu zanieczyszczeń w rzekach. Jest ona w stosunku do podejścia klasycznego rozbudowana o szacowanie niepewności oraz analizę wrażliwości modelu. W pracy zastosowano model martwych stref oraz wyniki eksperymentów znacznikowych przeprowadzonych na Wkrze. Zgodnie z proponowanym algorytmem przeprowadzono szacownie niepewności wyników symulacji z zastosowaniem...
