Query: Backstepping feedback control of open channel flow   We derive a feedback control law for the control of the downstream flow in a
1-D open channel by manipulating the water flow at an upstream location. We use
backstepping for controller design and Lyapunov techniques for stability
analysis. Finally, the controller is verified with simulations.
