Abstract:

Evaluating the potential environmental consequences associated with dredging and dredged material disposal is a challenging task. Scientific advancements have made possible the collection of large amounts of complex technical information. The dredged material manager must often weigh and balance multiple and sometimes conflicting lines of evidence to reach a decision and each decision involves a certain level of uncertainty. The application of Environmental Risk Assessment methods will increase a managers ability to make objective management decisions when data collected in Tiers 1-111 of the dredged material evaluation framework are insufficient for decision making.
