OPTIMAL-CONTROL PROBLEMS RELATED TO THE NAVIGATION CHANNEL ENGINEERING

The navigation channel engineering poses optimal control problems of h ow to find the optimal way of engineering such that the water depth of the channel is maximum under certain budget constraint, or the cost o f the engineering is minimum while certain goals are achieved. These a re typical control problems of distributed system governed by hydrauli c/sedimentation models. The problems and methods of solutions are disc ussed. Since the models, usually complicated, are nonlinear, they can be solved by solving a series of linear problems. For linear problems the solutions are given. Thus the algorithms are simplified.
