Dynamika ładunków związków azotu i fosforu wnoszonych przez Rabę do Zbiornika Dobczyckiego w latach hydrologicznych 2003-2005

Presented were the results of studies on the loads of biogenic NO3,NO2, NH4 and PO4 compounds delivered to the Dobczycki Reservoir with the Raba river waters. The investigations were conducted from May 2003 until October 2005 in the Osieczany hydrometrie cross-section located by the Raba inflow into the reservoir. The delivery of loads is characterized by a considerable dynamics of changes dependant on the season of the year. The lowest monthly mean daily loads were registered in the autumn months, whereas the maximum values occurred most frequently in March, May and July.
