ANUGA

ANUGA is a Shallow Water Wave (SWW) equation solver that performs calculations on a flexible triangular grid, using the finite volume approach. It has a robust methodology to deal with the wet/dry interface and also waves and shocks. This provides an extremely accurate model that is capable of showing hydrodynamic detail many other models are not capable of reproducing.

ANUGA was originally developed by Dr. Ole Nielsen (Geoscience Australia) and Dr. Stephen Roberts (Australian National University) and others to model Tsunami. It is based on work by Dr. Chistopher Zoppou and Dr. Stephen Roberts from 1999 on a MATLAB model that was used to assess the impact of Water Supply Reservoir failure in an Urban environment. It can handle extreme dynamic flow behaviour accurately tracks moving hydraulic jumps etc.

Rudy Van Drie became involved in ANUGA in 2006 and has been instrumental in moving to a Riverine Flood model with Rainfall applied directly to the 2D grid. Further culvert and bridge routines have been added, and there is ongoing work to add erosion/deposition capabilities.

Rudy has now trained many people in the use of the model including Prof. Andre Niemann of the University of Duisburg-Essen in Germany in January 2011.

If anyone is interested in training in the use of the ANUGA model they should contact Rudy.

ANUGA has now been used to model detailed flow between bridge piers… to massive catchments with rainfall directly on the 2D grid.
