Abstract
In the present study a one-dimensional numerical model for the simulation of unsteady flow in compound open channels is combined with an adaptive mesh refinement. To solve the applied Saint-Venant Equations the Godunov first-order upwind scheme with the source terms discretised according to Garcia-Navarro and Vázquez-Cendón (Garcia-Navarro and Vázquez-Cendón, 1998) was used. To minimize the errors due to an inflexible grid, an effective adaptive mesh refinement algorithm with refinement both in time and space has been implemented into the model.
