## Abstract

In this work, impulsive wave generation and propagation generated by landslides are studied numerically for a real case. Maku dam reservoir, in the northwestern of Iran is considered as the case study. Generated wave heights, wave run-up, maximum wave height above the dam crest and the probable overtopping volume have been evaluated, using a two-dimensional numerical model (LS3D). This model is validated using available three-dimensional experimental data for simulating impulsive wave caused by sub-aerial landslides. Based on the results, the generated wave height for first and second scenarios are 12 m and 18 m respectively. The wave height of 8 m is observed close to dam body. Because of the freeboard of 9 m, no dam overtopping happen in normal condition. In rainy seasons water level is close to spillway level, therefore the maximum wave height above dam crest is 4 m and the volume of flood overtopping is about 20000 m ^{3}.
