A stream with the cross-section shown in the previous figure has a flow rate of 5 m^3/s. The stream has a longitudinal slope of 0.002 m/m and a natural stony bottom (n = 0.050, stations 0 to 8). 

1. Using Manning's equation, what is the water surface elevation of the stream? 
2. What is the maximum capacity of the channel? 
3. How would the capacity of the channel be affected if you were to pave the center of the channel (n = 0.013) between stations 3 and 5?
