This lab session will be used for the midterm exam.
The directory $AM574/labs/lab8/shallow_1d_example1
has some sample code for solving the shallow water equations using the
Roe solver. This is discussed in this video.
That directory also contains an IPython notebook SW_riemann_tester.ipynb
illustrating the exact Riemann solution and the Roe approximation for the
shallow water equations. This makes use of two other Python modules also
in the directory: SW_exact_Riemann_solver.py and SW_phase.py.
