Abstract

The risk of landslides in water structures and dams is significant due to the direct

and indirect effects of water on the occurrence of landslides. When granular or

solid materials slide into a body of water such as a reservoir, lake, or sea, mass

momentum is transferred to the water mass, creating waves with large amplitudes.

This phenomenon is known as an impulsive wave in a reservoir or lake or as a

landslide tsunami in the ocean and sea. in this experimental study Due to the many parameters affecting the

characteristics of the wave and the complexity of the problem, there is a need for

extensive investigations in this field. In the present research, the waves created by

landslides in the reservoirs of dams and the characteristics of the waves created in

the dam reservoir, such as the length of the wave and the directions of wave

propagation, are investigated. The results showed that the highest wave energy in model 3 (13.258 kJ) occurred at a reservoir depth of 55 cm.
