EARTHQUAKE-TRIGGERED LANDSLIDE WAVES IN DAM RESERVOIRS

Impulsive waves in dam reservoirs may be generated by any type of geophysical mass flow, including debris flows, debris avalanches, landslides, and rock falls. This phenomenon may be endangering the dam stability, human life and devastating downstream cities. The estimation of the landslide generated waves amplitude is of the utmost importance in dam engineering and water reservoir planning. In this work, a higher order Boussinesq-type numerical model is applied to study the sensitivity of the wave amplitude to the landslide geometry and kinematics. The numerical wave model is verified successfully in several checks such as wave transition over an arbitrary bottom and the accuracy of numerical results in all cases are acceptable.
