Abstract
    In this report, an in-depth data analysis of the consolidation experiments described by (Meshkati Shahmirzadi et al. 2015a, 2015b) is presented. In particular, in this report we describe the temporal evolution of the vertical distribution of important rheological parameters i.e. Bingham yield stress and dynamic viscosity and we provide a detailed statistical analysis on grain fractions of mud samples. It is found that both the Bingham yield stress and the dynamic viscosity vary exponentially with density, even though this behavior is less pronounced for sediment from the harbor of Emden. With respect to the analysis of the grain fractions, we find that Ijmuiden, but especially Deurganckdok and Emden contain a relatively small amount of clay fractions, while Rotterdam and especially Emden are characterized by a relatively large amount of silt. Moreover, it turns out that mud from Emden and Rotterdam contains significantly less sand. Here, however, we should note that the presented grain-size distribution should be taken with care since the considered procedure to measure the grain size distribution does not provide unambiguous results. Furthermore, we find a lower percentage of dry matter within the mud of Ijmuiden and Emden. This indicates a higher swelling capacity, and therefore could provide an explanation to the observed lower consolidation rates. However, the swelling capacities have not been measured directly in this study.
