Abstract:

PARTICLE is a numerical computer model for the simulation of transport and fate of discharged, dissolved or suspended substances. The model is based upon the Lagrangian approach and calculates the mean and instantaneous concentration of suspended and sedimented material and the light attenuation caused by sediments in suspension. PARTICLE was developed as a tool for planning and monitoring of sediment plumes originating from dredging operations in connection with the construction of a fixed link across the Great Belt in the Danish waters. The large number of field measurements collected during intensive monitoring programs in the Great Belt gave a unique possibility for calibration of the model. A very good agreement between the model predictions and actual measurements was found.
