Dams break due to an earthquake, bombing, piping, overtopping, or some lack in design and construction process is unavoidable, which could lead to loss of life and property downstream of the dam. This study aims to understand of SILVEH dam break, under the scenario that considers the dam failure, due to overtopping and to prepare a hydrograph and flood zone downstream due to the failure of the SILVEH dam. In this research, obtaining and recognizing high-risk areas downstream of SILVEH Dam, due to dam break is another important goal. NAYS 2D FLOOD software has been used to simulate the failure of the SILVEH dam. SILVEH dam is an earthen dam, located in PIRANSHAHR city, in the West Azerbaijan Province. In the northern part of the study, immediately after the broken axis, the main flood flow dam in the valley is not very deep in the LAVIN River and due to the relatively steep slope, the water depth is not high and rarely rises from the river valley, but in the southern parts and reaching smoother areas are increases in the depth of flow. The maximum flood velocity is estimated at 20 meters per second and the lowest flood flow velocity is estimated at 2 meters per second. MAHABAD-PIRANSHAHR road and power transmission lines and bridges in the mentioned road will suffer the most damage from water floods due to the possibility of breaking the SILVEH dam.
