Abstract:In order to study the series of behavioral mechanisms including sediment erosion, re-suspension, transportation, this paper summarized the sediment re-suspension measurement method in three aspects: laboratory device simulation, in situ measurement and directly measurement in field. Sediment re-suspension measuring device can be divided into circulating water flume, straight flow-through flumes, and other devices. Hydraulic working principles, advantages and disadvantages, range of application environment of different devices were described. And the measuring results of different device were compared. Based on existing technologies and methods, the phenomenon of sediment re-suspension was quantified by measuring seabed erosion shear stress and suspended solids concentration changes. Different shearing force, testing time and equipment size and other factors cause the diversity of the result from all kinds of devices.
