Calibration of a Predictive Model for Instantaneously Discharged Dredged Material.

摘要

This report describes modifications to a computer model originally developed by R.C.Y. Koh and Y.C. Chang for predicting the physical fate of dredged material instantaneously released into a water column. Changes to the simulation include the calibration and verification of the program's models based upon experimental laboratory data as well as simplification of the model's use. Inputs to the model include initial material characteristics and dynamics,ambient characteristics and dynamics,and site geometry. Outputs include material concentration and position while in the water column and material mound height and concentration after bottom impact. Included in this report are a description of the model's structure,the changes made to the program,information on field sampling and laboratory procedures needed to develop input values,and examples of model operation.
