Inexpensive Method for Vibracoring Sands and Fine-Grained Sediments in Shallow Water

摘要

This technical note summarizes a coring methodology used in support of a Water Injection Dredging (WID) demonstration on the Upper Mississippi River in July 1992. The WID demonstration was sponsored by the Dredging Research Program (DRP) and was a joint effort involving the U.S. Army Engineer Waterways Experiment Station (WES), the U.S. Army Engineer Districts, St. Paul and Rock Island, and Gulf Coast Trailing Company. This note describes equipment, operational procedures, and capabilities of a vibrating coring system to collect subsurface sediments. The vibrating system was developed by the WES Coastal Engineering Research Center. The method used is a refinement of a coring system developed previously by Finkelstein and Prins (AD-A104 323). Information provided should assist in selecting inexpensive equipment and appropriate guidelines for shallow-water coring applications.
