Quantification of rheological parameters in deep‐sea mining plumes

open access: yesDeep Underground Science and Engineering, EarlyView.
This study explores the variations in rheological properties observed during the propagation of deep‐sea mining plumes, utilizing rheological test data obtained from kaolin clay plumes. Subsequently, taking into account the differences in sediment properties, the effects of clay content and clay mineral composition on the rheological parameters of ...
