This video shows the output of ANUGA hydrodynamic model simulating the total water level generated by a synthetic storm surge scenario corresponding to RP 100 years in Rimini. The period considered is 2050, that means the simulation accounts for changes in Mean Sea Level due to Sea Level Rise and vertical land movements. ANUGA is a 2D hydrodynamic model suitable for the simulation of flooding events resulting from riverine peak flows and storm surges. Being a 2D hydrodynamic model, ANUGA does not resolve vertical convection, waves breaking or 3D turbulence (e.g. vorticity), thus it not accounting for the swash component of wave runup. The fluid dynamics in ANUGA is based on a finite-volume method for solving the shallow water wave equations, thus being based on continuity and simplified momentum equation. The case study area is represented by an irregular triangular mesh in which water level, water depth and horizontal momentum are computed. The size of the triangles is variable within the mesh, varying from higher resolution areas (16 m²) for canals and coastal defence structures, to lower resolution (900 m²) for sea areas.
