ANUGA SOFTWARE FOR NUMERICAL SIMULATIONS OF SHALLOW WATER FLOWS

Abstract: Shallow  water  flows  are  governed  by  the  shallow  water  wave  equations,  also  known  as  the  Saint-Venant system. This paper presents a finite volume method used to solve the two-dimensional shallow water  wave  equations and  how the finite volume  method  is implemented in ANUGA software. This finite  volume  method  is  the  numerical  method  underlying  the  software.  ANUGA  is  open  source software  developed  by Australian  National  University  (ANU)  and  Geoscience Australia  (GA). This software  uses  the  finite  volume  method  with  triangular  domain  discretisation  for  the  computation. Four test cases are considered in order to evaluate the performance of the software. Overall, ANUGA is a robust software to simulate two-dimensional shallow water flows.

Keywords: finite volume methods, shallow water flows, ANUGA software, triangular grids, shallow water wave equations
