Much more recently, seawalls were built in 1623 in Canvey Island. https://www.announceamerica.com/katy/business/shore-protect-team, UK, when excellent floodings of the Thames tidewater happened, prompting the construction of defense for further events in this flood-prone location - erosion control. Ever since, seawall design has actually become a lot more complex and intricate in feedback to a renovation in products, technology, and an understanding of exactly how coastal processes run

The former French colonial territory of Pondicherry got away unscathed. This was primarily due to French designers that had constructed (and preserved) a huge stone seawall throughout the time when the city was a French colony.

At its highest possible, the barrier leaving the water's edge gets to about 27 feet (8.2 m) over sea level - https://photouploads.com/shrprtcttm.

Perhaps, the additional defense supplied by the seawalls presented an extra margin of time for citizens to evacuate and also quit some of the complete pressure of power which would have caused the wave to climb up higher in the backs of seaside valleys. The failure of the world's largest seawall, which set you back $1.5 billion to create, shows that developing more powerful seawalls to shield bigger locations would have been even less cost-efficient.
Essentially, the destruction in seaside locations and a last death toll forecasted to surpass 10,000 could push Japan to redesign its seawalls or consider more efficient alternative approaches of coastal protection for severe occasions. Such hard coastlines can also offer a false sense of safety and security to homeowner and regional residents as evident in this situation.
