SSFATE – Model to estimate the dispersion of dredged material plumes from dredging site Reference 1 Reference 2
Requirement	Approach
Suspended sediment concentration during dredging and placement	a)Short Duration TSS cruise will provide roving concentration around the dredge and discharge points. b) Sediview calibration of bottom-mounted ADCPs will allow the collection of stationary (in space) measures of TSS
Source term at the dredge. (Either we estimate this term as a percentage of the production rate, or we must know the operational parameters of the dredge and some information from the sediment)	a) Video and/or stills of the dredge operation. b) Need from the dredge operator: continuous production rate, rotation speed of cutterhead, ladder angle, swing rate, suction pressure, discharge pressure, dredge dimensions.
Hydrodynamics	Current measurements (adv and adcp) will assist in calibration of ADCIRC
Dredging parameters	Need the following information from the dredge operator: continuous production rate, dredge location
Sediment Parameters	Cores from the channel will assist in indentification of sediment types and distribution
