| Summary: | The problem of wave run-up is an important issue related to the tsunami disaster.
When a large tsunami wave hits the coast, it can propagate far inland and reach a
certain run-up height. Some research results suggest that in the bay area, the waves
achieve a higher run-up than the usual sloping beaches. Our study here uses the
Saint-Venant equations to model the wave dynamics in the bay, while numerically
we use the momentum conserving staggered grid (abbreviated as the MCS) scheme.
In this thesis, the problem of shoaling and wave run-up in two types of bays, namely
Bm and B
m bays, were examined. Our numerical results show a good fit when
compared to the analytical solutions in the literature. Therefore it can be concluded
that the MCS scheme is good and accurate for modeling wave run-up events in the
bay. |
