In this article. a central-upwind scheme (CUP) is extended to solve two-phase shallow granular flow (TPSF) model. The flow in this case is considered as incompressible and it is regarded to be a shallow layer of granular and liquid material. The model consists of continuity and momentum equations for both solid and liquid phases. https://countryscenesaddleryandpetsuppliers.shop/product-category/western-show-tops/
