Co-UDlabs’ Metrology Toolbox presented at SPN10 conference

Co-UDlabs participated in the 10th Sewer Processes and Networks international conference (SPN10) in Graz, Austria. SPN is a renowned global venue for advancement and knowledge-sharing on urban drainage and water management. Co-UDlabs coordinated a pre-conference workshop on August 23, 2022, for the first public release — specifically version 0.1.7 — of the Urban Drainage Metrology Tool (UDMT). UDMT is an open and free webapp developed entirely within one of Co-UDlabs’ Work Packages. UDMT includes five main toolkits based on advanced and automated algorithms and user-interfaces developed in Matlab, which provide figures and output files for:

  • Sensor calibration and surrogate sensor correlation,
  • Raw data correction from sensor calibration functions,
  • Data validation methods,
  • Uncertainty assessment of measurements, and
  • Processing data of tracing experiments.

The workshop was chaired by Jean-Luc Bertrand-Krajewski and Mathieu Lepot (INSA Lyon) and was attended by as many as 18 participants.

The workshop was also a very valuable opportunity to quickly introduce the audience to the Co-UDlabs project and its main achievements and objectives. A dedicated session for the UDMT also allowed to share basic concepts about the methods implemented in the Toolbox. The participants, moreover, could see the Toolbox at work for the first time. They were introduced to its goals and specifications, and participated in a demo presentation of some of the webapp’s key tools, especially uncertainty assessment, sensor calibration, data validation, and tracing experiments.

The chairs also invited the audience to join the UDMT Early Adopters Group, which will have the opportunity to test the UDMT in September-October 2022, report their own experience with the Toolbox, and recommend improvements, changes, and new developments as part of the UDMT users’ community. Participants were also invited to contribute to the Toolbox’s dissemination as well as provide additional examples and case studies to further test the webapp.

The first feedback was positive and showed an interest for the kind of tools implemented in the UDMT. Comments and suggestions collected during the workshop and in the next few days will be essential to improve the UDMT’s next version, which is expected to be available already in September 2022. All participants will be reminded to share any impressions and comments, and a final call for feedback will be opened by late October 2022 for additional improvements and updates.
