Final answer:

To determine the discharge through a section, we can use the Manning's equation: Q = (1.49/n) * (A * R^(2/3) * S^(1/2)). Given the normal depth, Manning's roughness coefficient, and channel slope, the equation can be used to find the discharge.

Step-by-step explanation:

To determine the discharge through a section, we can use the Manning's equation:

Q = (1.49/n) * (A * R^(2/3) * S^(1/2))

where:

  • Q is the discharge
  • n is the Manning's roughness coefficient
  • A is the cross-sectional area of flow
  • R is the hydraulic radius
  • S is the channel slope

Given that the normal depth is 5 ft, n = 0.013, and s = 0.2, we can substitute these values into the equation:

Q = (1.49/0.013) * (A * (5 ft)^2/3 * (0.2)^(1/2))

For further calculations, we need additional information about the shape and dimensions of the section.
