“…Type of incident flow: It has been reported in the literature [6][7][8][9][10] that the propagation of water over the deck differs considerably if the incident flow has unbroken or breaking features. With unbroken waves, it is possible to obtain types of green water such as those reported in [9,13,17], which resemble the DB, PDB, and HF types of this work.…”

“…The analysis of cavity entrapment in the interaction of incident flows with vertical structures (i.e., "flip-through" phenomenon) has been reported in the literature [70][71][72]. For the case of green water, although relevant strategies have been proposed to investigate this type of phenomena [14] and detailed experiments have been reported [9][10][11][12], more research is still needed to simulate cavity evolution and to verify its effects on structural loading [37].…”

“…Finally, as described by [2,8], the flow patterns over the deck will depend on the features of the incident waves, which can be unbroken (e.g., [9][10][11]17]) or broken (e.g., [5][6][7][8]73,74]). In the latter, if unsteady and broken flow can be observed on the deck (see the snapshots in Figure 16 and in [4]), then the application of numerical models, rather than analytical models, could be used for detailed research.…”

“…In ocean engineering research, experimental observations have suggested various patterns used to characterize different types of green water. Broken flow features are often seen, if they are generated by breaking waves [5][6][7][8], or air cavity formation at the start of the deck, if the incident waves are unbroken or partially broken [9][10][11][12][13][14]. In 2007, a classification of different types of green water was suggested by [9], who described the different events found in regular wave trains: The dam-break (DB), the plunging-dambreak (PDB), and the hammer-fist (HF) types.…”

Green water events may present different features in the initial stage of interaction with the deck of a structure. It is therefore important to investigate the evolution of different types of green water, since not all the events interact with the deck at the same time. In this paper, the evolution of three types of green water events (dam-break, plunging-dam-break, and hammer-fist) are studied. The water surface elevations and volumes over the deck in consecutive green water events, generated by incident [wave trains in a wave flume, were analyzed using image-based methods. The results show multiple-valued water surface elevations in the early stage of plunging-dam-break and hammer-fist type events. Detailed experimental measurements of this stage are shown for the first time. The effect of wave steepness on the duration of the events, maximum freeboard exceedance, and volumes were also investigated. Although the hammer-fist type showed high freeboard exceedances, the plunging-dam-break type presented the largest volumes over the deck. Some challenges for further assessments of green water propagation are reported.

“…As an example among the applications that require knowledge of water elevations, it is possible to mention the study of shipping of water on the deck of marine structures [11][12][13]. The shipping water phenomenon can cause significant overloading and structural damages in marine structures; nonetheless, it is a very complex problem in real conditions and difficult to analyze.…”
