摘要: An assessment of water quality measurements during a long-lasting low period in the Elbe River is presented. Weekly samples were taken from May to December 2003 at sampling site middle part River. For multivariate data analysis, 34 parameters 46 samplings considered. As result this 78% variance set explained by five factors. They can be assigned following latent variables: season (37.5%) > tributaries (12.7%) re-suspension (10.4%) discharge (9.4%) complexation (8.5%). investigated site, two key processes identified as dominating factors on conditions. First, seasonal phytoplankton development caused changes redox conditions with consequences for re-solution pollutants sediments. Second, have higher impact main stream, due mixing processes. Therefore, addition flood investigations, monitoring strategies, and management plans should developed order survey
