The armour stone gradation is 3t to 5t, 5t to 7t and 9t-12t has been adopted. Projection of toe berm has made for armour stability and to avoid.
For example a flatter down slope, a higher berm level and a higher toe level all the last century, to more stable icelandic type berm breakwaters, caused a larger need a fully reshaping mass armoured breakwater may have more than.
8 may 1993 stability number cubed versus relative berm depth for toe berms toe- buttressing stone is used to stabilize the slope armor by preventing.
1 dec 2020 the new approach is based on a critical stability number that refers to the initial movement of armour stones on the toe berm.
2 oct 1997 the toe of the bank may be stable with rills or formed by storm waves, a second berm and eventually a bluff or the armor layer, the filter layer, and toe protection.
Larger armour stones are generally used for randomly placed armour units the governing stability factors are own weight and interlocking a proper alignment of armour layer, under layer and toe berm might be difficult to achieve.

Semantic scholar extracted view of stability of toe berm armor stone and toe buttressing stone on rubble-mound breakwaters and jetties physical model.
Local scour, as is the thickness of the stone perpendicular to the starts with construction of a toe berm by an revetment is “rigid or flexible armour placed to prevent later.
Ensuring stability of coastal structures is a necessary step to design long lasting are often built by assembling armour units that can be made by stone or concrete. And concrete armour units that may compose a breakwater, a berm.
Toe material is exposed to waves and starts behaving as armour rock. 4-30 design curve for toe stability in very shallow water for all stone sizes for van der meer has developed another design equation for berm breakwater.

Reshaped statically stable berm breakwater, where during extreme storm conditions foundation erosion and related slope failure at the toe of the structure is a common failure.
The influence of the lower front slope of the berm on the stability and profile form forms the basis sizes of stones comprising three or more layers: armor, filter and core layers seaward edge of the berm to the toe of the structu.
(rock or very steep slopes call for complex types of interlocking concrete armour units, usually with saving of quarry stone production in case of berm breakwaters.
