Evaluation of Technology Options with Dredging

摘要

The group talked mainly about two topics: sediment removal and transportation, and ex situ treatment technologies. We spent a lot of time discussing dredging. The consensus was that there are a few dredging technologies. There is still quite a bit of concern about sediemnt resuspension and contaminant release and our ability to predict and estimate them. It was also agreed-although there were a couple of dissenters - that performance-based contracting for dredging is the way to stimulate advances in the U.S.dredging industry. Along with that, longer-term, larger-scale contracts will give the dredging companies more security so they can take more risks.
