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.
