A characterization model for time‐dependent displacement of concrete dams

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 23, Page 3707-3725, 19 September 2025.
Abstract Time‐dependent displacement caused by creep and shrinkage can significantly affect the structural performance and even shorten the service life of a concrete structure, which is designed for decades or longer, resulting in a safety risk. Unlike in long‐spanning structures such as bridges, where the time‐dependent displacement is readily ...

Air entrainment and splash characteristics in jet flows: Effect of downstream water levels

River, Volume 4, Issue 3, Page 287-296, August 2025.
Abstract This study investigates the air–water interaction dynamics in jet streams, with particular emphasis on the transition from the cavity to the far‐field regions. A dual‐tip conductivity phase‐detection probe was employed to analyze four distinct downstream water levels.

A three-dimensional elasto-plastic dynamic response procedure for concrete-faced rockfill dams

International Journal of Distributed Sensor Networks, 2018
Equivalent linear dynamic analysis is the primary method of analysis for concrete-faced rockfill dams during earthquake. However, this method cannot be directly used to estimate permanent deformation during earthquake, which is important to evaluate the ...

Geophysical imaging of the subsurface seismic structure of the Chestnut Hill Reservoir earth embankment dam (Massachusetts)

Near Surface Geophysics, Volume 23, Issue 2, Page 105-120, April 2025.
Abstract Degradation within a manmade earth embankment structure is often unobservable from the surface. In order to evaluate the structural integrity of earth embankment levees and dams and identify subsurface zones of weakness that may result in the future failures of such structures, various geophysical methods have been proposed as effective ...
