### Cross-Sections of the Pont du Gard Aqueduct **Figure 3.4** illustrates the cross-sections of the Pont du Gard aqueduct portions, which include the Elevated channel, Pont du Gard channel, and Subterranean channel. #### Channel Descriptions - **Elevated Channel**: - Shape: Square - Dimensions: 1.2 m (width) x 1.2 m (height) - **Pont du Gard Channel**: - Shape: Rectangular - Dimensions: 1.2 m (width) x 1.66 m (height) - **Subterranean Channel**: - Shape: Arch - Dimensions: 1.2 m (width) with a semi-circular arch of 0.6 m in height on top of a 1.15 m rectangular base #### Computational Task With Manning's coefficient \( n = 0.0125 \) for all channel portions, calculate the normal depth for flows ranging from 100 to 450 liters per second (lps), increased in 25 lps increments. Complete the table provided, which includes: - Discharge values (lps) - Calculations for: - Elevated Section \(( S_0 = 0.67 )\) - Pont du Gard Section \(( S_0 = 0.07 )\) - Subterranean Section \(( S_0 = 0.17 )\) - Another Subterranean Section \(( S_0 = 0.30 )\) These computations assist in understanding the hydraulic performance of each channel section under varying flow conditions.
