Macra2

Macra2 by Gruppo Maccaferri is a specialized engineering application for designing river and channel protection works that use flexible, rock-filled, and geosynthetic solutions. Built for hydraulic and civil engineers, it streamlines the assessment of flow conditions and boundary shear stress to help size and verify revetments—such as gabions and Reno Mattresses—for erosion control, bank stabilization, and river training projects.

Key capabilities:

• Guided workflows to define channel geometry, materials, and design discharges
• Calculation of essential hydraulic parameters (e.g., flow depth, velocity, shear stress)
• Stability checks to support sizing and selection of appropriate lining systems
• Comparison of alternative protection options and design scenarios
• Clear calculation summaries and printable design reports
• Support for both SI and US customary units

Macra2 helps teams move efficiently from concept to documented design, improving consistency and confidence in hydraulic protection solutions aligned with Maccaferri’s product portfolio.
