Open WL Archief (OWA)

During the first two campaigns, the focus was on mobilisation (connecting the periphery, adjusting the setup), demobilisation, manipulability, safety and the possibility of combining the various instruments. The integration of external parameters, data acquisition and data flow were also tested and fine-tuned.
A third measurement campaign focused on the repeatability, resolution and accuracy of the recorded data for density. For accuracy, a sampling that represents the ground truth is required. However, due to failure of the sampling equipment, this could not be done in-situ. As an alternative, a validation measurement was organised at Flanders Hydraulics Research where mud with known densities was measured.
The results of these measurements and a theoretical description of the measuring instruments considered are discussed in the following report.
