Stability of the mound under wave attack
For geotextile containers the stability of the mound under wave attack has been stud-
ied using small-scale model tests. Reference should be made to the calculation exam-
ple for geotextile containers in section 6.7.
Shear failure of the subsoil
As far as shearing of the subsoil is concerned, the design charts in Appendix C show
the maximum allowable wave heights at a

0.85 m was the design significant wave height and
consequently, the stability requirement is fulfilled.

Liquefaction
No danger of liquefaction exists in view of the slope being less than 1V:3H.
