Modified waterChannel tutorial to make case better posed

Browse Source 
Existing case did not properly converge and suffered slow convergence
with the water level failing to reach an equilibrium.  A slight rise in
the channel appears to help the water level reach an equlibrium when the flow
rate over the rise matches the inlet flow rate.
