Wave Impact Pressure-Impulse on Vertical Structures with Overhangs

The study of wave impact physics and magnitudes are key for the design of vertical coastal hydraulic structures. This research addresses the study of standing wave impacts on vertical coastal hydraulic structures with a relatively short horizontal overhang, which is especially relevant for structures such as lock gates, sluice gates, dewatering...

Effects of ventilations on coastal structures with overhangs subject to wave impacts

Coastal structures with horizontal overhangs are built due to design constraints, but wave loadings substantially increase under these confined geometries. Vertical structure elements, such as steel gates, are vulnerable to damage caused by impulsive wave impacts, potentially exposing the coastal zone to flooding and erosion. Existing formulas...

Validation of pressure-impulse theory for standing wave impact loading on vertical hydraulic structures with short overhangs

The applicability of pressure-impulse theory is evaluated for predicting wave impact loading magnitudes for non-breaking standing wave impacts on vertical hydraulic structures with relatively short overhangs. To this end, tests were carried out on a schematized but realistic configuration with low steepness regular wave impacts on a straight...

Smoothed Particle Hydrodynamic Modelling of Wave Impact: A numerical and theoretical analysis of non-breaking wave loads on structures with overhang

Hydraulic structures can be prone to impulsive wave impact, which is a highly stochastic and uncertain process. This type of impact, defined by extreme pressure peaks and a very short duration, is not only caused by breaking waves, but also by non-breaking standing waves on structures with an overhang, such as culverts and steel gates. In this...

Another Hit On The Wall: Confined Wave Impacts on Hydraulic Structures

Hydraulic structures are crucial for navigation, water management and flood protection in low-lying coastal and delta regions. Their importance is expected to continue growing in the coming years, because of the consequences of climate change and the continuous development and urbanization of these regions combined with more strict safety...
