2) Manning's equation can be used to compute the velocity of water in a rectangular open channel: n 0.0 where U velocity (m/s), S = channel slope, n = roughness coefficient, B = channel width (m), and H= water depth (m). The following data are available for five channels: 0.020 0.015 0.030 0.022 U= S B 0.0001 10 0.0002 8 0.0010 20 0.0007 24 0.0003 15 √S BH 2 n B + 2H H 2.0 1.0 1.5 3.0 2.5 a) Write MATLAB statements to store these values in a matrix P where each row represents one of the channels and each column represents one of the parameters. b) Write a MATLAB statement to compute the velocities in a column vector U based on the values in the parameter matrix. Display the resulting vector. c) Create a plot of n versus U. 2) Manning's equation can be used to compute the velocity of water in a rectangular open channel: n 0.0 where U velocity (m/s), S = channel slope, n = roughness coefficient, B = channel width (m), and H= water depth (m).
