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 ...

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 ...

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.

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 ...
