Özet: When a dam-break phenomenon occurs, the large amount of water rapidly starts to propagate towards the downstream and, the topography of the downstream has significant effects on the main characteristics of the dam-break flow. It has great importance to determine the main characteristics of the dam-break flows such as wave propagation velocity and water height in order to prevent possible disasters which can cause destructive effects in the impact area. Difficulties in obtaining field data of this type of flows increase the importance of experimental and numerical studies in this field. In the presented study, the numerical analysis of the dam-break flow with a trapezoidal hump in the downstream was performed by the Smoothed Particle Hydrodynamics (SPH) method. The solution capability of the SPH method was tested by the comparisons of the analysis results obtained from three different particle resolution with experimental measurements. In general, a good agreement was observed between experimental measurement data and numerical calculations and, the effect of particle resolution on the results was discussed.
