CONCLUSIONS: The USACE mission to provide safe and navigable waterways requires
maintenance dredging of inlet and entrance channels. Maintenance dredging comprises roughly
90 percent of the dredging volume, and approximately 80 percent of the cost. Simple adjustments
to existing operations, such as modifying the inlet and entrance infrastructure, dredging location,
placement of dredged material, and monitoring of projects can potentially yield cost savings.
Several of these methods and "lessons learned" have been described in this CETN by case
studies. Readers are encouraged to share successes, failures, and ways that they have modified
existing operation and maintenance projects to solve problems at inlets and entrances at the
Coastal Inlet Research Program's web page at http://cirp.wes.army.mil/cirp/cirp.html.
