- Diffusive wave approximation
- Local inertial approximation
Implementation of these two approximations for simulating the flood in Mobara city on October 25, 2019
Setting of the domain and boundary conditions
Results of the maximum inundation area calculated by the diffusive wave approximation, compared with the flood extent reported by Chiba Office
Results of the inundation range considering the flood recession by the local inertial approximation, compared with the flood extent estimated by Geospatial Information Authority of Japan (GSI).
