Abstract Employing a linear shallow water equation (LSWE) model in the spherical coordinates, this paper investigates tsunami waves generated by atmospheric pressure shock due to explosion of submarine volcano Hunga Tonga–Hunga Ha'apai on 15 January 2022. Using selected 59 records Pacific Ocean, an empirical is first constructed. Applying and realistic bathymetric data LSWE model, generation propagation are simulated Ocean. The numerical results show clearly co‐existence leading locked...
Results from Blind Test Series 1, part of the Collaborative Computational Project in Wave Structure Interaction (CCP-WSI), are presented.Participants, with a range numerical methods, simulate blindly interaction between fixed structure and focused waves ranging steepness direction.Numerical results compared against corresponding physical data.The predictive capability each method is assessed based on pressure run-up measurements.In general, all methods perform well cases considered, however,...
The main goal of this paper is to provide insights into swash flow dynamics, generated by a non-breaking solitary wave on steep slope. Both laboratory experiments and numerical simulations are conducted investigate the details runup rundown processes. Special attention given evolution bottom boundary layer over slope in terms separation, vortex formation development hydraulic jump during phase. Laboratory were performed measure velocity fields means high-speed particle image velocimetry...
Abstract. This study presents a comprehensive nationwide tsunami inundation assessment of New Zealand. It utilises wave amplitude data from recent probabilistic hazard (covering seven return periods at the 50th and 84th percentiles) computationally efficient model. modelling approach enhances accuracy previous exposure assessments, which have been limited by inconsistent simplified techniques. produces maps for 14 along entire Zealand coastline. These integrated with land cover...
Both one-dimensional in the horizontal direction (1DH, dispersive and non-dispersive) two-dimensional (2DH) axisymmetric (approximate, analytical solutions are derived for water waves generated by moving atmospheric pressures. For 1DH, three wave components can be identified: locked propagating with speed of pressure, $C_p$ , two free opposite directions respective celerity, according to linear frequency dispersion relationship. Under supercritical condition ( $C_p > C$ which is fastest...
Abstract This paper develops a tsunami inundation model, filling the current void between industry applied simplified methods (bathtub and attenuation) comprehensive numerical modeling. The proposed model utilizes two‐dimensional equations established on hydraulic principles (energy conservation friction loss) to produce finite‐difference, model. While sophistication of depth‐averaged modeling has not been entirely replicated, incorporation roughness gravitational effects (slope) through...
Abstract The purpose of the European Flooding Directive (2007/60/ CE ) is to establish a framework for assessment and management flood risks. aim reduce adverse flooding consequences on wide range topics such as human health, environmental cultural heritage, economic activity. In Spain, coastal zone hazard risk maps are managed by Environment Spanish Ministry ( MAGRAMA , D irección G eneral para la S ostenibilidad de C osta y el M ar ). These designed using methodology explained in this...

Abstract. We applied machine learning to improve the accuracy of present predictors wave setup. Namely, we used an evolutionary-based genetic programming model and a previously published dataset, which includes various beach conditions. Here, two new setup predictors: simple predictor, is function height, wavelength, foreshore slope, fitter, but more complex also sediment diameter. The results show that outperform existing formulas. conclude models are capable improving predictive capability...
A new methodology is proposed for the generation of breaking focused waves in computational fluid dynamics (CFD) simulations. The application illustrated a numerical flume with piston-type wavemaker built CFD model olaFlow. Accurate control over spectral characteristics wave group near inlet and location focus/breaking are achieved through empirical corrections input signal. Known issues related to spatial temporal downshift focal focusing groups overcome. Focused produced first- second...
