Researchers at the U.S. Army Engineer Research and Development Center (ERDC) are working in support of ERDC’s Flood and Coastal Risk Management Program to better inform efficient and economic dam safety monitoring by studying how the use of fully grouted vibrating wire piezometers compares to traditional methods.

The geotechnical community has promoted fully grouted vibrating wire piezometer installations over conventional piezometers because of their ability to successfully monitor multiple zones within the same borehole. This method also requires fewer drilled holes, resulting in a reduced overall drilling cost.

To accomplish their data collection, ERDC researchers worked in collaboration with the USACE Nashville District, which provided the test site, and the USACE Savannah District, which provided drilling equipment and expertise.
