Effects of Sediment on the Aquatic Environment: | NRCS

Sedimentation in the fluvial/estuarine interface is another area that requires more in-depth research. This area is very sensitive to disturbance because of the change in gradient and the sediment storage that occurs at this transition (Phillips 1991). Mobilization of this stored sediment can have a dramatic impact on the quality of the estuary.

GEOL342 - Sedimentation and Stratigraphy

Bedform deposition and erosion:. Small irregularities in the bottom cause a slight turbulence as flow is diverted up and around them such that the flow over an obstacle no longer hugs the bottom, but separates from it at the point of flow separation (analogous to a stall in an aircraft wing). This flow separation creates a zone of reverse circulation downstream of the obstacle.
