In-line laser holography and video analysis of eroded floc from engineered and estuarine sediments.

Microphytobenthic polymers mediate intertidal sediment erosion processes, through biostabilization and modifying the nature of eroded floc material. The latter is of key importance with respect to sediment transport dynamics, including floc aggregation and particle deposition. In this study, eroded floc material was analyzed by video imaging, alongside novel application of in-line laser holography (ILH).
