1. Determine normal depth

here is a Matlab program to calculate normal depth, (
(SI unit) Normal depth program (Right Click->Save Link as )
 (English Unit: matlab program to find normal depth

2. Determin critical depth
 

3. Determine the flow condition (subcritical or supercritical flow ?)
 

4. Numerical computation of the backwater profile in gradually varied flow.
   Refer to the Chapter 10, pg 463-471 of the text book
 

5. Home Work (due 9/21)
   For the sample problem 10.9 ( page 465), use MS Excel to write a program or table to perform the computation.
   Plot the water surface profile (x = distance, z= surface elevation), normal depth, and critical depth
   Work in 2-people group, and submit the results by e-mail to me.
