    11= Welcome to the ANUGA Inundation Modelling Project (Powered by Subversion and Trac 0.8.1) =
     3Geoscience Australia and the Australian National University are developing a hydrodynamic inundation modelling tool called ANUGA to
     4help simulate the impact of hydrological hazards. The core of ANUGA is a fluid dynamics module, which is based on a finite-volume
     5method for solving the Shallow Water Wave Equation. The study area is represented by a mesh of triangular cells. By
     6solving the governing equation within each cell, water depth and horizontal momentum are tracked over time.
     8A major capability of ANUGA is that it can model the process of wetting and drying as water enters and leaves
     9an area. This means that it is suitable for simulating water flow onto a beach or dry land and around structures such as
     10buildings. ANUGA is also capable of modelling hydraulic jumps due to the ability of the finite-volume method
     11to accommodate discontinuities in the solution.
     13To 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.
     16Most ANUGA components are written in the object-oriented programming language Python. See
     17for more background on ANUGA.
