KOLOS

KOLOS is a wave-dissipating concrete block intended to protect coastal structures like seawalls and breakwaters from the ocean waves.

KOLOS has been conceptualized by incorporating structural improvements to existing armour units, Dolos.

The common failure modes for Dolos were found to be either at the shank due to torsion and at the fluke by bending-induced shear.

[2] The higher structural stresses are caused largely due to the longer lever arm.

To fabricate KOLOS, three piece steel moulds are used which facilitate easy de-moulding.
