Abstract
The details of the transport of riverine sediments to the ocean are not fully understood (Geyer et al., 2004; McCool and Parsons, 2004). Normally the freshwater-particle mixture is lighter than estuarine saltwater such that most river plumes are positively buoyant. Thus, the particles can be transported over relatively large distances with the freshwater current until their settling dominates over the horizontal transport. Generally, two different settling modes are known to increase the average particle settling speed significantly (McCool and Parsons, 2004): flocculation of individual particles forming larger effective aggregates with larger Stokes settling speeds (Geyer et al., 2004) and the settling enhancement due to turbulence (McCool and Parsons, 2004).
