• If the predicted magnitude and timing of risk reduction as a result of dredging are likely to be achieved.

  • The key site-specific factors that contribute most to achieving high dredging effectiveness.

  • The short-term and long-term impacts on ecologic communities as a result of dredging.

  • Monitoring strategies in use and proposed for use at dredging sites and whether these strategies are sufficient to inform assessments of effectiveness.

  • The specific types of assessments useful for measuring effectiveness, in particular, measuring the reduction of risk.

  • How conclusions about completed and ongoing dredging operations can inform decisionmaking in the future.

It is expected that sources of information available for this assessment would include megasites for which dredging has been completed; megasites for which plans have been developed; partially implemented, and operations are ongoing; and smaller sites that exhibit lessons relevant to megasites.
