Fortran 2003 models for solving the one-dimensional shallow water equations with topography and friction using Godunov-type finite volume and discontinuous Galerkin methods. Models can run with wavelet-based adaptivity enabled, or with adaptivity disabled on uniform meshes. The code can be compiled using a recent version of GFortran and CMake. Other fortran compilers have not been tested. To compile the code from the root directory of the unzipped download: mkdir build && cd build cmake .. make -j Running the numerical solvers The FV1, DG2, adaptive HFV1 and MWDG2 solvers are all implemented in a single executable, run_simulation. To display usage information about required and optional command line switches: ./run_simulation --help A suite of one-dimensional test cases are preconfigured.
