Geofluids, Volume 2026, Issue 1, 2026.Reservoir seepage is a critical issue that must be addressed during the design phase of water conservancy projects. Based on engineering geological and hydrogeological investigations, a three‐dimensional geological model was established for a dam site in the Huaihe River Basin.

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.The unclear impact of temperature on rockfill dam settlement and the lack of a solid basis for selecting temperature parameters in prediction models are problematic. These issues significantly limit the accuracy and applicability of deformation monitoring models for rockfill dams.

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.

Effects of porosity on strength and deformation of rockfill materials
Yantu gongcheng xuebao, 2018 In view of the rockfill materials utilized in a 300 m - grade high earth-rock core rockfill dam to be constructed, large static triaxial tests under different porosities are performed to analyze the influences of porosity on strength and deformation of ...
