HYDROCHEMICAL FLOOD FLOW OF THE VISTULA -AUGUST 2001
Journal Title: Biuletyn Instytutu Morskiego - Year 2001, Vol 28, Issue 2
Abstract
Intense rain in the south em part of the Vistula 's watershed in July 2001 resulted in floods in many places and in flood water flows on the Vistula and its tributan·es. T7re culmination of the flood reached the Gulf of Gdansk in the night of51h August 2001. In the period 4lh to 61h August, 10 samples of water were taken, and d1e content of biogenic substances and of other components in these samples was detennined. Basing on water flow measurements and on the content of the investigated components, the loads were calculated and compared with mean multi-annual loads for the pen·od 1984- 1998. It was found that the mean biogen load, related to water flow, was exceeded many times. Also the relationships between the analysed components, water flow and variability during the period of investigations were detennined. Obtained results show that there may be a very significant influence of biogens on the condition of the environment and on the dynamics of biocenotic processes of the Gulf of Gdansk in the period before and after the propagation of flood waters of d1e Vistula.<br/><br/>
