Macra1

Macra1 is a specialized engineering tool from Gruppo Maccaferri designed to support the design and verification of hydraulic erosion protection works. Tailored for river, channel, and shoreline applications, it helps engineers size and check Maccaferri systems such as gabions, Reno mattresses, and rock armoring under a range of hydraulic conditions.

Key capabilities:

• Assists in the design of revetments and linings for riverbanks, channels, spillways, and transitions using gabions and Reno mattresses.
• Estimates hydraulic actions (such as flow velocities and boundary shear) and sizes rock fill and mattress thickness accordingly.
• Performs stability checks for structures like gabion weirs and drop structures, including sliding, overturning, and uplift verifications.
• Supports customizable inputs (discharge, slope, roughness), user-defined safety factors, and both SI and US customary units.
• Produces clear calculation summaries and bill-of-quantities outputs to aid documentation and project communication.

Macra1 applies well-established design approaches for hydraulic protection systems. It is intended for use by qualified professionals and should be applied in conjunction with project-specific standards, codes, and engineering judgment.
