What Is the Accropode Single-Layer Armor Breakwater Calculator?
Accropode and Accropode II are unreinforced concrete single-layer interlocking armor units designed to protect coastal breakwaters and revetments against extreme oceanic waves.
Unlike traditional double-layer rock or Tetrapod armor, Accropode utilizes a high stability coefficient (KD ~ 15-16) and interlocking face geometry to form an exceptionally stable single-layer armor revetment.
This calculator computes individual unit mass, concrete volume, layer thickness, and packing density per 100 m² of seaward slope.
How Does the Accropode Single-Layer Armor Breakwater Calculator Work?
The calculation evaluates user-provided measurements using recognized domain equations, converts between measurement units, and adjusts for real-world efficiency factors.
Accropode Single-Layer Armor Breakwater Calculator Formula & Variables

Assumptions & Limitations
- Accropode units are strictly placed as a single layer with specific orientation rules to maintain interlocking.
- Slopes steeper than 4:3 (cot θ < 1.33) require specialized toe buttressing to prevent toe slippage.
- Seawater density is taken as 1025 kg/m³ in accordance with standard coastal engineering practice.
