In section 3, modification of the method is clearly defined, followed by discrete formulation of governing equations. Then, the time- ... In weakly compressible SPH, pressure is calculated by the Tait equation of state defined as [18]: WebTait equation of state. Inspired by Finite Volume formalisms, Vila (Vila, 1999) proposed to rewrite the SPH formalism initially developed by Monaghan (Monaghan, 1992). A Riemann solver in a Lagrangian framework was introduced, leading to increased stability properties of the scheme. Combined with the MUSCL (Monotone Upwind Centered
