“…First, Equations ( 5) and ( 6) given by [3,4], respectively, for non-overtopped rubble mound breakwaters in breaking conditions are compared to Equation ( 14) with K 1 = 0.06 and K 2 = 5 for the front slope of overtopped rubble mound breakwaters. Equation (5) given by [3] can be rewritten for the data in this study as…”

“…Higher sea levels will reduce dimensionless crest freeboards leading to higher overtopping rates. In overtopped mound breakwaters (crest freeboard similar to the design significant wave height), part of the wave energy passes through the structure [5]; the wave energy is dissipated not only in the armored front slope, but also in the armored crest and rear slope. Thus, the hydraulic stability of the front slope, crest and rear slope becomes relevant for design purposes and related to the overtopping.…”

Armor damage due to wave attack is the principal failure mode to be considered when designing conventional mound breakwaters. Armor layers of mound breakwaters are typically designed using formulas in the literature for non-overtopped mound breakwaters in non-breaking wave conditions, although overtopped mound breakwaters in the depth-induced breaking wave zone are common design conditions. In this study, 2D physical tests with an armor slope H/V = 3/2 are analyzed in order to better describe the hydraulic stability of overtopped mound breakwaters with double-layer rock, double-layer randomly-place cube and single-layer Cubipod® armors in depth-limited breaking wave conditions. Hydraulic stability formulas are derived for each armor section (front slope, crest and rear slope) and each armor layer. The front slope of overtopped double-layer rock structures is more stable than the front slope of non-overtopped mound breakwaters in breaking wave conditions. When wave attack increases, armor damage appears first on the front slope, later on the crest and, finally, on the rear side. However, once the damage begins on the crest and rear side, the progression is much faster than on the front slope, because more wave energy is dissipated through the armored crest and rear side.

“…On the other hand, great environmental stresses are derived from the construction sector: 30% of global energy consumption, 40% of extraction of raw materials and 30% of greenhouse gas emissions are associated with the construction sector [4]. Consequently, sustainability and climate change are arising as new design criteria for infrastructure [5][6][7]. Another relevant aspect in construction practitioners is professional ethics, where preserving or enhancing prestige and professional image may conflict with some of the sustainability aspects.…”

Analyzing Sustainability Awareness and Professional Ethics of Civil Engineering Bachelor’s Degree Students

Teaching sustainability and ethics to engineering students is a challenging but necessary task that has been increasingly investigated during the last few years. In this research, a systematic method to identify the level of awareness in students about sustainability and ethics is developed. Here, it is applied to students studying the Civil Engineering bachelor’s degree at the School of Civil Engineering of Universitat Politècnica de València (UPV), though this method is potentially applicable to equivalent ABET and EUR-ACE accredited bachelor’s degrees. A survey was performed, and data was analyzed using Analytical hierarchical process technique; this technique determines the relative importance of each criterion, as well as the consistency of the emitted judgements, in an objective manner. These results allowed to discover that students do not have a robust opinion related to sustainability and ethics, except those students with previous experience in the construction sector. Environmental and social dimensions of sustainability and ethics were identified as the main focuses to emphasize in the civil engineering curriculum. Finally, actions to boot these principles are also proposed; potential courses where sustainability and ethics concepts could be explicitly included were selected and the inclusion of an environmental budget in the bachelor thesis was recommended, among others suggestions.

“…The flow characteristics, overtopping flow velocity and layer thickness, are closely related to the stability 1 1. INTRODUCTION of coastal structures (Van Gent, 2002b;Argente et al, 2018;Mares-Nasarre et al, 2021). For example, the overtopping flow velocity and layer thickness are used as input in some erosion models (Dean et al, 2010;Hoffmans, 2012;Van Bergeijk et al, 2021) to estimate the cover erosion and stability of earthen dikes.…”
