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.

Modeling Static Behavior of Rockfill Materials Based on Generalized Plasticity Model
Advances in Civil Engineering, 2019 Rockfill materials are commonly used for dam construction. Establishing an effective model that can reasonably describe the mechanical properties of rockfill material is very important for the calculation of earth-rock dam engineering.

Numerical analysis of earthquake response of an ultra-high earth-rockfill dam
, 2013 Abstract. Failure of high earth dams under earthquake may cause disastrous economic damage and loss of lives. It is necessary to conduct seismic safety assessment, and numerical analysis is an effective way. Solid-fluid interaction has a significant influence on the dynamic responses of geotechnical materials, which should be considered in the seismic ...

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 ...
