Journal of Flood Risk Management, Volume 19, Issue 2, June 2026.ABSTRACT The reliability of flood event simulations is a crucial aspect in terms of saving lives. The worst flood scenarios derive from possible dam failures. For earthen dams, the breaching mechanism, triggered by overtopping or piping, is affected by several modelling uncertainties, which propagate downstream and may influence flood hazard mapping ...

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.

Pull-out test analysis of steel bar in rockfill materials
Shuili Shuiyun Gongcheng Xuebao, 2017 As an effective seismic strengthening measure for the earth rock dam, the reinforcement is used more and more widely in the construction of high earth rockfill dams. A premise of the reinforcement design is the research on the contact characteristics and

Creep behavior of rockfill with soft rock under different relative densities
Yantu gongcheng xuebao, 2020 When soft rock is used as the dam embankment materials for high earth-rock dams, large creep deformation may occur, which is very unfavorable to the long-term stability of high earth-rock dams.

Applicability of additive mass method in density tests on soil-mixture materials
Yantu gongcheng xuebao, 2023 The additive mass method (AMM) has been applied in the density tests on different materials of many earth-rockfill dams. With the development of hydropower projects in recent years, the soil-rock mixtures (S-RM) with wide gradation and high fines content

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.

Water Resources Research, Volume 61, Issue 11, November 2025.Abstract Addressing the limitations of traditional overtopping risk analysis methods, which either consider only a single failure mode or fail to accurately characterize the nonlinear characteristics of reservoir levels, this paper proposes a novel overtopping risk model for dams.

Calculation of rockfill deformation based on the generalized plastic framework
Shuili Shuiyun Gongcheng XuebaoRockfill is the primary load-bearing material in earth-rock dams, crucial for withstanding water pressure. Developing a constitutive model that accurately describes its mechanical properties is essential for predicting the stress and deformation in high ...

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.
