Long-term health monitoring of levee cutoff wall under Garden Highway in Sacramento by DFOS technology

US Army Corps of Engineers is currently implementing a levee improvement project along the American River in Natomas, California…..With support from the National Science Foundation and USACE, the [Berekely Engineering] research team (Ruonan Ou, Andrew Yeskoo, Linqing Luo, John Murphy, Yaobin Yang) embedded optical fiber sensors into the Slug cement bentonite cutoff wall at Natomas Reach I during its construction in July 2020….The monitoring will continue for years to evaluate the performance of the SCCB wall during and after construction, operation and possible flooding and earthquake events.
