Identification of the Friction Coefficient for Steady and Unsteady Shallow-Water Flows
This work presents some recent results on the solution of shallow-water flows using the finite element method and the optimal control method for distributed systems. The objective is to identify the friction coefficient for steady and unsteady flows, such as the numerical solution is close to the measurement data. We investigate the following aspects: the finite element discretization, the regularization of the cost function and the solution algorithms. Several benchmark tests are presented.
