“…The time interval between the consecutive ship-wake waves ranged from 10 to 20 s. Eight distinctive ship-wake waves were identified from the nearshore measurements. The ship-wake wave period of 10-20 s (Figure 4), determined based on the time interval between consecutive peaks, is much longer than the typical wake waves reported, which are likely controlled by the size of the ship [21][22][23]35,36].…”

“…Soomere [21] provided an extensive review of long waves generated by moving ships in semi-enclosed shallow water bodies. Fenical et al [22] measured a water surface elevation fluctuation of up to 1 m in magnitude and 120 s in period caused by deep-draft vessels in the Corpus Christi Ship Channel, Texas, USA. Didenkulova et al [23] discussed the potential of using waves generated by fast-moving ferries as a physical model for studying tsunami and found that ship-generated tsunamis would provide an ideal natural laboratory to simulate landslide-induced tsunamis.…”

The displacement of a large amount of water in a moderate-sized estuary by a fast-moving mega-ship can generate tsunami-like waves. Such waves, generated by cruise ships, were observed in Tampa Bay, Florida, USA. Two distinct, long tsunami-like waves were measured, which were associated with the passage of a large cruise ship. The first wave had a period of 5.4 min and a height of 0.40 m near the shoreline. The second wave had a period of 2.5 min and was 0.23 m high. The peak velocity of the onshore flow during the second wave reached 0.65 m/s. The shorter, second wave propagated considerably faster than the first wave in the breaking zone. The measured wave celerity was less than 50% of the calculated values, using the shallow water approximation of the dispersion equation, suggesting that nonlinear effects play an important role. A fundamental similarity among the generation of tsunamis, as induced by mega-ships, landslides or earthquakes, is a process that causes a vertical velocity at the sea surface, where a freely propagating wave is produced. This mega-ship-generated tsunami provides a prototype field laboratory for systematically studying tsunami dynamics, particularly the strong turbulent flows associated with the breaking of a tsunami wave in the nearshore, and tsunami–land interactions. It also provides a realistic demonstration for public education, which is essential for the preparation and management of this unpreventable hazard.
