Investigation of wave characteristics generated by mass landslides and the effect of their arrangement on wave features in a reservoir

This study experimentally investigates how specific factors, such as the arrangement of concrete cylinders, ramp angle, and the presence or absence of a downstream barrier, influence shock wave characteristics to improve risk prediction accuracy. To do this, three models were considered: two sequential, distant pairs of cylinders (Model ۱); two sequential, adjacent pairs of cylinders (Model ۲); and four sequential, separate cylinders (Model ۳). The concrete cylinders were released into the tank in different models and at three different slopes, either with a downstream barrier or without. The results showed that, when using a downstream barrier, the maximum wave height in models ۱, ۲, and ۳ decreased by ۱۴.۵%, ۱۰.۵%, and ۸.۶۳%, respectively, at three different angles. Comparing results for a particular angle revealed that waves generated by model ۳ had higher values in wave height, length, and amplitude among all models. Additionally, the maximum water level fluctuations in Model ۳ were ۱۰.۱% and ۵.۴% higher than those in Models ۲ and ۱, respectively. Increasing the ramp angle in Model ۳ raised the wave height by ۱۴.۴%.
