Lagrange-Projection Exactly Well-Balanced Finite Volume Schemes for the Ripa Model
摘要
In this work we propose a strategy to numerically solve the Ripa model by applying the Lagrange-projection approach. We design both first and second order finite volume schemes that are exactly well-balanced for this model, preserving the well-known lake at rest steady-states as well as the constant pressure for the flat topography case.
