PURPOSE This Coastal and Hydraulics Engineering Technical Note CHETN describes two methods to quickly assess sediment mobility relative to water depth as a function of local waves and currents. Estimating dredged sediment mobility relative to placement depth and grain size is valuable for preliminary or reconnaissance engineering studies to compare multiple placement sites. Presently, a Matlab script is available to perform the calculations using both methods. Future development will include an interactive web tool with automated data uploads for engineers to utilize.
