Zander, F. (author), Comans, R.N.J. (author), Gebert, J. (author)Degradability of organic matter in river sediments differs in relation to origin and age. In order to explain previously observed spatial patterns of organic matter degradability and stabilization, this study investigated sediment organic matter (SOM) properties along a tidal Elbe river transect using dissolved organic matter (DOM) fractions,...journal article 2023

Zander, F. (author)Organic matter plays a major role in global ecosystems and has several functions in terrestrial and marine environments. As organic matter impacts, among others, the rheological behaviour and settling rates of mineral sediment particles, it is of great relevance to the definition and maintenance of the nautical depth in ports and waterways. The...doctoral thesis 2022

Shakeel, A. (author), Zander, F. (author), Gebert, J. (author), Chassagne, C. (author), Kirichek, Alex (author)The presence of clay-organic flocs in cohesive mud results in a complex rheological behavior of mud, including viscoelasticity, shear-thinning, thixotropy and two-step yielding. In this study, the effect of microbial degradation of organic matter on the rheological properties of mud samples, collected from different ports, was examined. The mud...journal article 2022

Zander, F. (author), Shakeel, A. (author), Kirichek, Alex (author), Chassagne, C. (author), Gebert, J. (author)Purpose<br/>Sediment organic matter (SOM) influences settling and thus the rheological behavior of suspended particles by enhancing flocculation or reducing surface charges by forming organo-mineral complexes that facilitate particle–particle interactions in consolidating sediments. It was, therefore, assumed that the microbial degradation of...journal article 2022

(author)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...journal article 2022

Zander, F. (author), Groengroeft, A. (author), Eschenbach, A. (author), Heimovaara, T.J. (author), Gebert, J. (author)Anaerobic sediment organic matter decay generates methane, delays sediment consolidation, reduces sediment density, viscosity and shear strength, all impacting the sediment rheological parameters and the navigable depth. This study quantifies the share of anaerobically and aerobically degradable sediment organic matter (SOM) in a depth...journal article 2022

Zander, F. (author), Heimovaara, T.J. (author), Gebert, J. (author)Purpose: The microbial turnover of sediment organic matter (OM) in ports and waterways impacts water quality, sonic depth finding and presumably also rheological properties as well as greenhouse gas emissions, especially if organic carbon is released as methane. As a consequence, sediment management practices as a whole are affected. This...journal article 2020
