The Sunday Observor in Sril Lanka reported that Japan got a 23 foot Tsunami on March 11, 2011.

From a Civil Engineering perspective, to stop a 23 foot Tsunami wave, the water restraining system must be higher, higher than 23 feet.

Previous study about the Netherlands systems showed section where the height was more than 30 feet and an area where the height was so high it was approaching 40 feet.

It needs to be high to stop such a Tsunami wave and it also needs to be wide so that is not breached and the choice of materials has to be strong so that the water restraining system is not breached.

For example reinforced cement has been used to construct caissons with water restraining systems.
