roblem #2 Normal Depth – Rectangular Channel This problem will require the use of Excel, MATLAB, or other software. You must attach your spreadsheets and/or codes for me to review. For a rectangular channel, Slope = 0.0001, 15 ft bottom width: a refer to Table 5.1.1 in Chapter 5 of Mays and determine the normal depth for a discharge of 100 cfs using Manning’s roughness coefficients for Concrete (5.1.1, B-2c – pick 1), Channels not maintained with dense weeds (Ce1), Flood plains (D-2 – pick 1), and Major streams (D-3 – pick 1)—make sure you do not repeat roughness values. b Plot normal depth (y-axis) vs Manning’s roughness (x-axis) – label your x and y-axis c In a few sentences, explain what happens to normal depth as we change our Manning’s roughness.
Problem #2 Normal Depth – Rectangular Channel
This problem will require the use of Excel, MATLAB, or other software. You must attach your
spreadsheets and/or codes for me to review.
For a rectangular channel, Slope = 0.0001, 15 ft bottom width:
a refer to Table 5.1.1 in Chapter 5 of Mays and determine the normal depth for a discharge
of 100 cfs using Manning’s roughness coefficients for Concrete (5.1.1, B-2c – pick 1),
Channels not maintained with dense weeds (Ce1), Flood plains (D-2 – pick 1), and Major
streams (D-3 – pick 1)—make sure you do not repeat roughness values.
b Plot normal depth (y-axis) vs Manning’s roughness (x-axis) – label your x and y-axis
c In a few sentences, explain what happens to normal depth as we change our Manning’s
roughness.
Hint: All normal depths range from 2 ft to 12 ft
