“…A solitary wave is generated by a piston-type maker and travels 180m until reaching the final inclined slope. A schematic view of the wave flume is depicted in Fig 3 . More details about the experiment can be found in [63][64][65]. Fig.…”

This work presents a partitioned method for landslide-generated wave events. The proposed strategy combines a Lagrangian Navier Stokes multi-fluid solver with an Eulerian method based on the Boussinesq shallow water equations. The Lagrangian solver uses the Particle Finite Element Method to model the landslide runout, its impact against the water body and the consequent wave generation. The results of this fully-resolved analysis are stored at selected interfaces and then used as input for the shallow water solver to model the far-field wave propagation. This one-way coupling scheme reduces drastically the computational cost of the analyses while maintaining high accuracy in reproducing the key phenomena of the cascading natural hazard. Several numerical examples are presented to show the accuracy and robustness of the proposed coupling strategy and its applicability to large-scale landslide-generated wave events. The validation of the partitioned method is performed versus available results of other numerical methods, analytical solutions and experimental measures.

“…Hydraulic loading exerted by extreme hydrodynamic events on buildings comprises impulsive forces (short-duration, transient) induced by wave breaking, hydrodynamic forces (quasi-static, strong turbulence) (Al-Faesly et al, 2012;Robertson et al, 2013;Krautwald et al, 2022), debris impact forces (short-duration, transient, very strong) (Nistor et al, 2017;Derschum et al, 2018;Stolle, Derschum, et al, 2018), debris damming forces (quasi-static once established, unknown probability, evolution process) Shekhar et al, 2020), as well as buoyancy forces (Yeh et al, 2014), depending on building envelop state (Yeh et al, 2015). A forensic survey after Hurricane Ike making landfall in Texas, US, found storm surge and wave related building damage, dislodgement, and entire collapse correlated with relative vertical distance between lower floor elevation to maximum surge level on structures (Robertson et al, 2008;Kennedy et al, 2011).…”

“…Since these authors compared a slab-on-grade and an elevated structure, the focus of this study was on the evaluation of soft-storey failures, which can occur in hurricane but also in tsunami conditions. Vertical hydrostatic and hydrodynamic loads become a significant concern in the design of elevated structures (Moon et al, 2019;Alam et al, 2020;Winter et al, 2020;Krautwald et al, 2022), with additional failure mechanisms depending on their architectonical features such as girders or floor joists (Duncan et al, 2021;Krautwald et al, 2021). In contrast, the present study considers other failure mechanisms, which are associated with a rapid, impulse-type loading that is present when large tsunami waves with considerable duration strike.…”

“…The Ningbo-Zhoushan Port Main Corridor project is crucial in the development of Zhoushan because it connects the Zhoushan Mainland-Islands Link Project in the south and Daishan Island in the north as well as joins Changbai Island through the Changbai Interchange constructed in the sea [1,2]. Large-scale bridge construction usually impacts local hydrodynamic characteristics [3][4][5].…”

Ningbo–Zhoushan Port Main Corridor project is important in the development of Zhoushan City, but its impact on the hydrodynamic characteristics of the Zhoushan sea area is still unclear. Finite volume method is used in the present study to solve the shallow water equations and establish a plane two-dimensional tidal current numerical model. The measured tidal current data of the Yangtze River Estuary and Hangzhou Bay is utilized to verify the accuracy of the model in simulating the tidal current process. The results indicate the model can numerically reproduce the tidal current process in the Hangzhou Bay–Yangtze River Estuary–Zhoushan sea area (HYZ). In addition, the dynamic characteristics of tidal currents in the Zhoushan sea area with and without piers are compared. The results show that the construction of the project changes the water level near the bridge piers and causes the water obstruction and deficiency in the front and behind the piers, respectively. Tidal flow velocity increases on sides of the piers with while a low velocity area is formed before and after the piers. The project construction exerts a small impact on the tidal currents but a strong influence on the local area near the bridge piers.
