Effect of organic matter degradation in cohesive sediment: A detailed rheological analysis

Purpose<br/>The presence of organic matter in cohesive sediment results in the formation of clay-organic flocs, which eventually impart complex rheological behavior including shear-thinning, viscoelasticity, thixotropy and two-step yielding to mud. In this study, the influence of microbial degradation of sediment organic matter on the...

From fundamentals to implementation of yield stress for nautical bottom: Case study of the Port of Hamburg

The nautical bottom (i.e., the level at which contact with a ship’s keel causes either damage or unacceptable effects on controllability and manoeuvrability of a ship) should be associated to a measurable physical characteristic. Bulk density is typically used as a criterion for nautical bottom by many ports worldwide. However, the rheological...
