The numerical simulations implemented by a CFD software. The results showed that SWE model had lower accuracy, in reproducing the wave evolution and bed deformation, compared to the 3D model. Furthermore, the kinematic and dynamic properties of the dam-break wave affected by the initial conditions and bed characteristics. dam break numerical models CFD SWE 3D models dam break numerical models CFD SWE 3D models https://jonarbset.ir/downloadfilepdf/11572
