A review of empirical dam breach models

River, Volume 5, Issue 3, Page 328-350, August 2026.
Abstract Dam breach modelling is central to flood risk assessment, yet the empirical models commonly used for estimating breach parameters display considerable variability and uncertainty. This review evaluates the performance of widely applied empirical dam breach models and identifies those that consistently show lower uncertainty, such as the ...

Effect of particle shape on the dynamic deformation characteristics of artificially simulated rockfill material

Shuili Shuiyun Gongcheng Xuebao
Rockfill material, as the primary construction material for earth-rock dams, exhibits dynamic deformation characteristics under seismic action that are influenced by particle shape, gradation, and relative density.

Contrasting Abiotic and Biotic Predictors of Diatom Resource Use Efficiency in a Megadam‐Regulated River

Environmental DNA, Volume 8, Issue 5, September‐October 2026.
Megadam regulation was associated with contrasting relative importance of abiotic and biotic predictors of diatom chlorophyll‐based resource use efficiency. Reservoir RUE was more strongly associated with phylogenetic diversity, network complexity, and stability, whereas downstream RUE was mainly associated with turbidity, temperature, and nutrient ...

Implications of heterogeneous embankment conditions for geoelectrical investigations on dams: A case study at Mactaquac Dam, Canada

Near Surface Geophysics, Volume 24, Issue 4, Page 303-324, August 2026.
Abstract Electrical resistivity tomography (ERT) has been shown to be effective for surveying and monitoring dams, due to the method's sensitivity to moisture content and relevant physical properties (e.g., porosity). Automated ERT systems, capable of time‐lapse monitoring, can be used to detect variations in ground conditions.

Effects of toe configuration on throughflow properties of rockfill dams [PDF]

, 2021
Rockfill dams must be equipped with defence mechanisms to counteract the destabilizing effects of throughflow forces under accidental leakage scenarios. A key component of the rockfill dam overtopping system is the rockfill dam toe, constructed in tandem

Influence of the Uncertainty in the Dam‐Breach Hydrograph on the Flood Hazard Assessment in a Valley Area

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 ...

Non-linear response of the rockfill in a concrete-faced rockfill dam under seismic excitation

, 2014
This study investigates the non-linear response of the rockfill in a concrete-faced rockfill dam under seismic excitation for various concrete slab thicknesses from 30 to 100 cm thick. The effect of the friction in the concrete slab rockfill interface on
