WebMar 2, 2024 · Design a riprap apron for the following CMP installation. Available riprap classes are provided in Table 10.1. Given: Q = 2.33 m 3 /s D = 1.5 m TW = 0.5 m Solution Step 1. Calculate D 50 from Equation 10.4. First verify that tailwater is within range. TW/D = 0.5/1.5 = 0.33. This is less than 0.4⋅D, therefore, use TW = 0.4⋅D = 0.4⋅1.5 = 0.6 m. WebBureau of Reclamation
