Determine n_m, for the model channel.

A river model is to be constructed using Yr = 1/100 and Xr = 1/500, which provides a vertical exaggeration of 5 to 1. The prototype channel has an average depth of 5 m, an average width of 120 m, a discharge of 1500 m3/s, a slope of 0.00032. and a Manning n = 0.021.

Determine the corresponding geometry of the model channel and the required model discharge. Verify that turbulent Row will occur in the model, and calculate both model and prototype Froude numbers (based on the average depth).
