What did Seawall / Sea Dyke look like?

Built with dressed stone blocks arranged in interlocking (dog-tooth) patterns, connected by iron dovetail tenons. The sea-facing wall is stepped or sloped to dissipate wave energy.

How did Seawall / Sea Dyke work?

Waves strike the seawall → stepped/sloped face causes wave breaking → energy gradually dissipates → tenon-joined stones bear load as a unit → individual blocks are not overturned by waves → the area behind the levee is protected.

Seawall / Sea Dyke

A stone seawall with staggered mortise-and-tenon joints and wave-dissipating structural design to disperse wave impact forces, protecting coastal farmland and settlements.

Scientific Principle

Wave mechanics: stepped/rough slope faces increase wave energy dissipation. Structural integrity: mortise-and-tenon connections resist impact loads.
