As she worked through the calculations, Alex realized that the culvert's size and shape would have a significant impact on its hydraulic capacity. She decided to use a rectangular box culvert with a 3-meter width and 2-meter height. She assumed a Manning's roughness coefficient of 0.015 and a slope of 0.005.

This is decided based on the road width and the fill height over the box. : Covers Reinforced Concrete Box Culvert standards and
Determined by hydraulic requirements (e.g., Maine.gov suggests an opening 3 times the cross-sectional area of the stream). Thickness (t): A common rule of thumb is (e.g., a 3m high culvert needs 300mm thickness). Concrete Strength ( ): Usually 30 MPa to 40 MPa (4 ksi to 6 ksi). Steel Strength ( ): Typically 420 MPa (60 ksi). 2. Load Calculations
