Abstract

There is continuing need to underpin the definition of hydrological parameters in assessing alterations in the flow dynamics of urban rivers, which have to be considered alongside qualitative impacts within an ecologically meaningful integrated assessment of the ecological status of urban rivers. The study addresses how combined sewer and storm water outflows change the hydrograph in urban rivers during storm events, and identifies appropriate hydrological parameters for this analysis. Discharge data sets from 15 flow events in two urban rivers in Germany were analysed to characterise the changes in the flow dynamics of urban rivers which are caused by both types of outlet. Their highly variable impact was shown to be dependent on event and antecedent conditions. The hydrological parameters can be used to consider the range of changes in flow dynamics This is important for analysis of urban rivers.
