The U.S, Army Corps of Engineers (USACE) recently completed a study that evaluated options for "wave mitigation" or reduction of storm surge, in Two Rivers' harbor. The study, completed at a cost of about $130,000, was jointly funded by the USACE and the City.
The orientation of our harbor channel, opening to the southeast, has historically made the harbor susceptible to waves coming from that direction. Such wave action bounces off the various hard surfaces surrounding the harbor, creating unsafe conditions and damaging docks and boats. Along with the surge issue comes shoaling, or the buildup of sand bars between the piers in the outer harbor. That shoaling creates yet another navigation hazard, and has resulted in the need for frequent, expensive dredging of the outer harbor.
Using data collected during several storm events in 2015, this study evaluates the effectiveness of various structures in reducing, or mitigating wave action in the harbor. It will be used by the City to advocate for funding of harbor modifications in the future. (Note: both piers are the property of the US Army Corps of Engineers.)
