To support decision makers in planning effective combined sewer overflow (CSO) management strategies an integrated modelling and impact assessment approach has been developed and applied for a large urban area in Berlin, Germany. It consists of an urban drainage model, a river water quality model and a tool for the quantification of adverse dissolved oxygen (DO) conditions in the river, one of the main stressors for urban lowland rivers. The coupled model was calibrated successfully with average Nash-Sutcliffe-efficiencies for DO in the river of 0.

- - This paper analyzes data from five online monitoring campaigns of sewer systems in cities including Berlin and Bogota, utilizing UV-VIS spectrometers and turbidimeters to assess water quality during dynamic events like stormwater overflow.
- - It emphasizes the importance of local calibration for accurate Chemical Oxygen Demand (COD) measurements, recommending a collection of 15-20 samples over various events to capture natural variability.
- - The paper highlights that without proper local calibration, the accuracy of measurements can be significantly compromised, leading to high error rates in assessing water pollution during wet weather discharges.
