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 ...

Empirical Predictions on Wave Overtopping for Overtopping Wave Energy Converters: A Systematic Review

Processes
Over the past three decades, the development and testing of various overtopping wave energy converters (OWECs) have highlighted the importance of accurate wave run-up and overtopping predictions on those devices. This study systematically reviews the empirical formulas traditionally used for predicting overtopping across different types of breakwaters ...

Flood Risk Management Using Representative Hillslopes: Insights From a Historical Flood in Southwest Germany

Hydrological Processes, Volume 40, Issue 5, May 2026.
A coupled hydrologic and hydraulic modelling framework relying on representative hillslope models and scaled using hydraulic routing schemes is proposed to simulate Hortonian overland flow at intermediate scales. Using a reconstructed historic summer storm in southwest Germany (1994), we show how hillslope scale nature‐based flood prevention measures ...

Generation and Dissipation of Infragravity Waves Over Natural and Engineered Chenier Plain During Hurricane Laura

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract Infragravity (IG) waves play a crucial role in nearshore hydrodynamics and sediment transport; however, their generation and dissipation mechanisms during extreme storms remain challenging to assess due to limited data availability, site‐specific characteristics of natural landscapes, and anthropogenic effects.

Reshaping of San Jose Island, TX, USA, by Unconfined Washover and Channelized Washout During Hurricane Harvey

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.
Abstract Hurricane Harvey (2017) produced 31 net‐erosional washout channels on San Jose Island, Texas, USA, where offshore‐directed flows cut through two dune ridges and the beach. Channel growth was affected by natural, pre‐existing aeolian topography, rather than prior washover channels or infrastructure. We investigate how offshore directed outwash,

Field study of post-overtopping flow impacts on a vertical wall at the crest of an upper-beach dike

Applied Ocean Research
In many urbanized shorelines, upper-beach sea-defenses and coastal buildings can be exposed to the impact of wave induced post-overtopping flow during energetic storm conditions.

UPDATE OF THE EUROTOP NEURAL NETWORK TOOL: IMPROVED PREDICTION OF WAVE OVERTOPPING

Coastal Engineering Proceedings, 2017
The goal of this work is to present a synthesis of the improvements and updates developed to deliver the final version of the ANN tool adopted by the second edition of the wave overtopping manual, EurOtop, released on the internet in 2016. This tool consists of three identical but independent ANNs able to predict the main parameters representative of ...

Barrier island erosion and overwash study -- effect of seawalls. Volume 2 [PDF]

, 1992
This is the second of a pair of reports documenting the effects of storms on beach systems including the presence of seawalls. With the aim of simulating the effects of overwash on barrier islands with seawalls and characterizing their response, a ...

Tsunami generation by paddle motion and its interaction with a beach: Lagrangian modelling and experiment [PDF]

, 2013
A 2D Lagrangian numerical wave model is presented and validated against a set of physical wave-flume experiments on interaction of tsunami waves with a sloping beach. An iterative methodology is proposed and applied for experimental generation of tsunami-
