Flow measurements in sewer systems based on image analysis : automatic flow velocity algorithm

  title={Flow measurements in sewer systems based on image analysis : automatic flow velocity algorithm},
  author={David Jeanbourquin and Daniel Sage and L. Nguyen and Basile Schaeli and Subhradeep Kayal and David Andrew Barry and Luca Rossi},
Discharges of combined sewer overflows (CSOs) and stormwater are recognized as an important source of environmental contamination. However, the harsh sewer environment and particular hydraulic conditions during rain events reduce the reliability of traditional flow measurement probes. An in situ system for sewer water flow monitoring based on video images was evaluated. Algorithm to determine water velocities was developed based on image-processing techniques. The image-based water velocity… CONTINUE READING
