Abstract |
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. |
