PREDICTIVE METHOD FOR ASSESSING THE IMPACT ON MAINTENANCE DREDGING IN AN ESTUARY
The physical, chemical and biological processes which are altered during a typical maintenance dredging operation are analyzed. A conceptual model is used to relate the various processes and to serve as a guide in preparing dynamic models for quantification of key parameters such as suspended sediment transport and deposition. Actions and processes during the dredging and post-dredging period are discretely separated into dredging, spoiling and equilibration categories. Equilibration in the estuary is manifested in adjustments in the system hydraulics to satisfy the basic laws of conservation of mass and energy, and recruitment, colonization and re-establishment of benthic communities for the new set of environmental conditions.
