Abstract
This work proposes a new fuzzy logic based high resolution (HR), total variation diminishing (TVD) scheme in finite volume frameworks to compute an approximate solution of the shallow water equations (SWEs). Fuzzy logic enhances the execution of classical numerical algorithms. To test the effectiveness and accuracy of the proposed scheme, the dam-break problem is considered. A comparison of the numerical results by implementing some classical flux limiting methods is provided. The proposed scheme is able to capture both smooth and discontinuous profiles, leading to better oscillation-free results.
