Os modelos numéricos têm vindo a adquirir um peso cada vez maior na resolução de problemas complexos no âmbito da engenharia hidráulica. No entanto, esses modelos não são ainda uma ferramenta totalmente consolidada em casos de estruturas hidr

Esta comunicação reúne contribuições recentes de estudos dos autores sobre os efeitos da altura relativa do escoamento, da dimensão relativa dos sedimentos do leito, do tempo, da forma dos pilares e do seu ângulo de viés em relação à dire

An experimental campaign of 8 long-duration tests on scouring at complex piers was carried out under steady clear-water flow conditions. The aim was to evaluate the contribution of complex pier components on the total local scour depth. Data was also

Throughout the planning and design of hydraulic structures, engineers and researchers are increasingly integrating computational fluid dynamics (CFD) into the process. Despite reports of success in the past, there is still no comprehensive assessment

The paper summarizes recent contributions of the authors on the effects of relative flow depth, relative sand size, time and fluid viscosity, on the scour depth at single piers. These contributions rely on unique experiments in the sense that they ar

Introduction: Infrastructures such as bridges are simultaneously influenced by and influence both the sediment transport and the river or estuarine morphology. The interventions in bridges often have impacts on sediment transport, hence being necessa

The main objective of this study is to evaluate and compare three available methods for the prediction of the local scour depth around complex bridge piers using new experimental data. The complex pier model used in the study was embedded in uniform

The scour depth evolution around single piers has a unique logarithmic trend under clearwater, according to diverse authors. However, in the case of complex piers, corresponding to a column funded in a pile cap supported by a pile group, the scour de
