Abstract: | In this work, a two-dimensional fourth-order Boussinesq-type numerical model is applied to estimate the impact of landslide-generated
waves in dam reservoirs. This numerical model has recently been extended for simulating subaerial landslides. The extended
model is validated using available three-dimensional experimental data, and a good agreement is obtained. The numerical model
is then employed to investigate the impact of landslide-generated waves in two real cases, the Maku and Shafa-Roud dam reservoirs
in the northwestern and the north of Iran, respectively. Generated wave heights, wave run-up, maximum wave height above dam
crest, and dam overtopping volume have been estimated for each case. The amplitude of generated waves about 18 and 31 m and
the volume of dam overtopping up to 80,000 m3 emphasize the importance of the estimation of the landslide-generated waves in dam sites. |
