  • Case study - Discharge measurement at the river

    Due to the seasonally strong weed growth and low flow during low water periods the measurement of water level and flow at the measurement site "Kleinraschuetz“ was rather distorted. It had to be corrected by putting in additional manpower for manual measurements. Therefore it was decided to modernize the station completely and to install a stationary discharge measuring system. The ...

  • Influence of local calibration on the quality of online wet weather discharge monitoring: feedback from five international case studies

    This paper reports about experiences gathered from five online monitoring campaigns in the sewer systems of Berlin (Germany), Graz (Austria), Lyon (France) and Bogota (Colombia) using ultraviolet–visible (UV–VIS) spectrometers and turbidimeters. Online probes are useful for the measurement of highly dynamic processes, e.g. combined sewer overflows (CSO), storm events, and river ...

  • On-line measurements provide more accurate estimates of nutrient loading: a case of the Yläneenjoki river basin, southwest Finland

    Automatic on-line measurement stations for water quality components and water level were equipped with dataloggers and GSM transmitters; the stations were installed at two sites in the Yläneenjoki river basin, SW Finland. Measurements during five seasons in 2006–2007 were conducted to find out whether the produced data would provide more accurate estimates of material and nutrient transport than ...
