Resumo: | Climate change studies already reported sea level rise as an accepted scenario, which induces changes in nearshore wave conditions. A large range of new experiences including water level, run-up, overtopping, hydrodynamic data for different wave steepnesses and directions was performed in the Leibniz Universität Hannover (LUH) wave basin for a rubble mound breakwater with a slope of 1(V):2(H). This work presents, focusing on oblique extreme wave conditions, numerical simulations of the hydrodynamics in that experiment using OpenFOAM®. Results of the wave generation boundary conditions and their propagation, namely elevation of the water level free-surface and velocity data at specific locations are compared and discussed with data from experimental measurements acquired by acoustic wave gauges and acoustic doppler velocimeter (ADV) / Vectrino equipment. Although an exact match between numerical and laboratory values was not reached, an appropriate incident wave angle and a reasonable amplitude of velocities and water depths was achieved and the same happened to the statistics of those values. |

Foram realizados ensaios no tanque de ondas de Leibniz Universität Hannover (LUH), para avaliar o comportamento de um quebra-mar de taludes com uma inclinação de 1 (V): 2 (H), quando sujeito à incidência de condições de agitação marítima e níveis de maré extremos, resultantes desses cenários de alterações climáticas. Foram efetuadas simulações numéricas dos ensaios efetuados. Este trabalho apresenta em particular, simulações numéricas da hidrodinâmica dos ensaios com foco em condições de ondas extremas oblíquas, usando OpenFOAM®. Foram reproduzidas as condições de fronteira de geração de onda e analisados os resultados da sua propagação, a elevação da superfície livre e dados de velocidade em locais específicos que são comparados e discutidos com dados de medidas experimentais adquiridas por medidores de ondas acústicas e velocímetro doppler acústico (ADV) / Equipamento Vectrino. Embora uma correspondência exata entre os valores numéricos e laboratoriais não tenha sido alcançada, um ângulo de onda incidente apropriado e uma amplitude razoável de velocidades e profundidades de água foram alcançados e o mesmo aconteceu com as estatísticas desses valores.APRHRCIPLCarvalho, R.
