# hydraulicmodel
Flood modeling by 2D shallow water equation.
Refer to Hunter et al (2005), Bates et al. (2010).
Please refer to the following paper on the detailed implementation and results.

## Diffusive wave approximation
## Local inertail approaximation
## Time steps in two methods
- 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
