Learning extreme wave run-up conditions

Applied Ocean Research, 2020
Abstract Wave inundation in coastal regions is an ubiquitous hazard, and near-shore bathymetric variations can significantly influence the dynamics of such events. A multifaceted approach is developed in this work to identify environmental conditions, primarily the coastal profiles, aiding in extreme wave run-ups. The near-shore bathymetry profile is

Note on wave run-up

Journal of Geophysical Research, 1970
A comparison is made of total run-up of breakers on beaches predicted by present theory and observed in channel experiments. The inviscid theory is shown to predict the observed dependence of run-up on bore strength, but not that on beach slope. A tentative, simple friction correction proposed by Le Mehaute brings theory and experiment into much better

Wave Run-Up On Shore Structures

Journal of the Waterways and Harbors Division, 1956
Laboratory tests determining run-up on shore structures as a result of wave action are described. Curves relating the run-up to wave steepness, structure type, and depth at structure toe are presented.

A Synthesis on Wave Run-Up

Journal of the Waterways and Harbors Division, 1968
A critical survey of existing theories and experiments on wave run-up is carried out. The theories of run-up of nonbreaking waves are analyzed first. Breaking criteria and the main theories of run-up of breaking waves are presented, including the theories for the run-up of a bore, the nonsaturated breaker theory, and the numerical method for ...

Wave Run-up Influence on Overtopping of Levees

Journal of the Hydraulics Division, 1979
A procedure for calculating probabilities of overtopping from the combined occurrence of floods and wave run-up with an application to a section of the Waal river in the Netherlands is presented. Annual exceedance probabilities are known for the floods. Run-up is computed from wind velocity and wind direction. A stochastic model for these quantities is

Reliability analysis of wave run-up

2009
Assessing the run-up arising from ocean waves as they reach a coastal or offshore structure is an important aspect of engineering projects. By combining formulations for calculating the run-up of regular waves with wave statistical descriptions, a procedure is implemented to assess wave run-up in random sea conditions. This procedure uses the First and

Wave Run‐up on sloping structures

Eos, Transactions American Geophysical Union, 1953
Relationships have been developed from laboratory experiments which show the effect of side slope, wave steepness (H/L), relative depth (d/L), and the structure porosity on wave run‐up. Maximum wave run‐up occurs, for the range of angles examined, at approximately 30°.

Wave run up dynamics at Jogehama beach

2016 Techno-Ocean (Techno-Ocean), 2016
Big wave suddenly invaded to the beach, and three children were carried off to the sea by the wave though they played on the beach. The beach characteristic topography has the cusp topography and steep slope. This study tried to comprehend the reason why this accident occurred.

Spectral characteristics of random wave run-up

Coastal Engineering, 1988
Abstract The time series of shoreline variations (run-up variations) due to random waves have been measured on uniform sloping beaches with slopes ranging from 1 5 to 1 30 and the energy spectra of the variations (run-up spectra) have been examined. The main characteristics of run-up spectra obtained from the experimental results are as
