“…Scientific efforts have been aiming to establish physical, mathematical and numerical modellings of impulse waves in order to mitigate accidents caused by them (Raney & Butler, 1976, Maciel, 1991Heinrich, 1992;Monaghan & Kos, 2000;Maciel & Nascimento, 2002b;Quecedo et al, 2004;Choi et al, 2007;Panizzo et al, 2005;Zweifel et al2007;Pastor et al, 2009;Abadie et al, 2010;Bosa & Petti, 2011;Cremonesi et al, 2011;Tinti et al, 2011;Vasco et al, 2011, Yin et al, 2015Shi et al, 2016;Wang et al, 2017;Si et al, 2018;Chen et al, 2020;Romano et al, 2020;Takabatake et al, 2020;Amaro et al, 2021;Cheng et al, 2021;Rauter et al, 2021;Zhang et al, 2021;Sabeti & Heidarzadeh, 2022). The first systematic studies related to the phenomenon were performed soon after the nuclear tests in the Bikini Atoll in 1946 (Hager & Evers, 2020).…”

This note proposes a technical approach towards the disaster occurred on January 8, 2022, in the tourism region of Capitólio (Minas Gerais state, Brazil), where a massive quartzite rock broke from a cliff and toppled on to pleasure boaters drifting on a lake, leaving 10 people dead and 30 others injured. Even though the rockfall was decisive in the tragedy, it is reasonable to affirm that the submersion-wave impact certainly potentialized the accident. Along these lines, this work not only aims to videographically explore the geometric / kinematic characteristics of the solid block, but also to discuss the specificities pertaining the event. Lastly, with basis on the Noda Method (1970), this manuscript also estimates the resulting wave amplitude (near the impact) and the energy-transfer coefficient between the block and the body of water.

“…The influence of added mass and hydrodynamic damping on different wave frequencies and heading are explored. Junior et al [29] developed and evaluated a new three-dimensional fully Lagrangian (particlebased) numerical model based on the hybrid discrete element method (DEM) and the moving particle semi-implicit (MPS) meshless technique for simulating highly dynamic ice-wave interactions.…”

The marginal ice zone (MIZ) is located at the junction of ice-covered areas and open water, where waves cause ice floes to break up and change their state of motion, thus threatening the safety of ships navigating the ice. This study employs the Structured Arbitrary Lagrangian–Eulerian (S-ALE) method and the numerical wave-making method based on dynamic boundary conditions to numerically examine the motion response of ice floes in waves. The longitudinal motion of ice floes in waves can be classified into two distinct states, namely irregular and regular, depending on the wavelength. In the short-wave range, the ice floes exhibit primarily irregular motion, whereas in the long-wave range, their motion becomes regular, resembling that of isolated ice floes. The longitudinal motion response of the ice floes remains unaffected by their size. However, the longitudinal velocity, surge velocity, and displacement of the ice floes are influenced by the wavelength. Furthermore, the numerical calculations are compared to the model test conducted in a towing tank using paraffin artificial ices, revealing a qualitative agreement between the experimental and numerical results.
