Abstract |
On November 20th 2012, at the initiative of Dutch Rijkswaterstaat (RWS), an international measurement campaign on the river Meuse at Maastricht (NL) took place with hydrometrists from the Flemish HIC, Dutch RWS and Walloon SETHY. The aim was to compare by means of simultaneous ADP-measurements the results produced by the calibration instruments of all three institutes and to favor best-practices and knowledge exchange.Each group brought into action a trimaran mounted RDI-Rio Grande ADP instrument, while RWS additionnally put in the “Observant”, a small manned and ADP equipped measuring vessel. While the trimarans were consecutively towed between the Meuse banks from the “Hoge Brug” with 4 tracks per participating group, the Observant was sailing, slightly upstream (100m) and simultaneously without interruption, some 40 bank-tobank tracks. This report compares all measured discharge data to the simultaneous discharge data produced by the upstream acoustic flowmeter at MSW St.Pieters (ADM) with a 15 minute time shift taken into account. Tables are displaying the results of all sailed tracks, while AGILA-graphs present the averaged cross section shapes and the stream velocity distributon measured by all ADP-devices. Finally, a comparison is made of the Observant vs. the trimaran results and, on the other hand, of the Observant discharge data and the ADM ones. |
