Co-UDlabs_WP6_T61_EAWAG_004_DischargeKeeper

This dataset documents the comparison between sewer flow measurements collected with the DischargeKeeper of Photrack AG via Surface Structure Image Velocimetry (SSIV) and Nivus ultrasonic flow sensors. Data covers timestamped flow rates, depth, and velocity measurements from an experimental combined sewer site in Dübendorf, Switzerland (Eawag HALL laboratory). Analysis scripts and structured FAIR metadata are included to support reproducibility and reuse.
