The Sediment Test Tank (STT) has been built on the terrain of Flanders Hydraulic Research (FHR) to host in-situ sediment for sediment studies. After delivery (16/04/2009) of 50 m³ of sediment from the harbour of Zeebrugge at a density of 1.14 m³/s, sedimentation and consolidation created vertical differences in the sediment in the STT. The measurements started on 21/04/2009. This report deals with the measurements until 26/05/2010.A whole range of parameters have been measured over time and depth to monitor the sediment characteristics as much as possible. Some parameters are measured in situ in the tank, e.g. measurements by the YSI-multiparameter probe and pore pressure measured by piezometric tubes. Other parameters are measured on undisturbed samples, e.g. density, rheological parameters and thermo-gravimetric analysis. This report gives the findings of the measurements and recommendations for further measurement campaigns in the STT
