| 3 | Geoscience Australia and the Australian National University are developing a hydrodynamic inundation modelling tool called ANUGA to |
| 4 | help simulate the impact of hydrological hazards. The core of ANUGA is a fluid dynamics module, which is based on a finite-volume |
| 5 | method for solving the Shallow Water Wave Equation. The study area is represented by a mesh of triangular cells. By |
| 6 | solving the governing equation within each cell, water depth and horizontal momentum are tracked over time. |
| 7 | |
| 8 | A major capability of ANUGA is that it can model the process of wetting and drying as water enters and leaves |
| 9 | an area. This means that it is suitable for simulating water flow onto a beach or dry land and around structures such as |
| 10 | buildings. ANUGA is also capable of modelling hydraulic jumps due to the ability of the finite-volume method |
| 11 | to accommodate discontinuities in the solution. |

| 13 | To set up a particular scenario the user specifies the geometry (bathymetry and topography), the initial water level |
| 14 | (stage), boundary conditions such as tide, and any forcing terms that may drive the system such as gravity, wind stress or rainfall. |
| 15 | |
| 16 | Most ANUGA components are written in the object-oriented programming language Python. See http://datamining.anu.edu.au/~ole/anuga/user_manual/anuga_user_manual.pdf |
