Excel spreadsheet for the hydraulic and structural design of mattress-type gabions. The sheet provides automated calculations for design flow, stable river width, and Manning’s roughness coefficients to determine hydraulic performance and scour depth.
The stability analysis section includes formulas for calculating active earth pressure, weight per linear meter, and factors of safety against sliding and overturning. It evaluates eccentricity and provides verification for structural stability under specific soil and hydraulic loads. Calculations use metric units for flow rate (m3/seg), velocity, and wall height.
