Abstract:
Underwater-landslide-generated waves were studied in a physical laboratory model. Number of 102 sets of laboratory data with a set-up covering all of the three main stages of generation, propagation, and runup of were collected in a wide range of effective parameters. An empirical method was presented for prediction of impulse wave run-up caused by underwater landslide in a dam reservoir by using the primary information about slide geometry, initial submergence, still water depth, and sidewalls slopes. The presented method was successfully verified using earlier laboratory-based empirical equations and an accuracy of ±15% was obtained. The presented method was also applied in a real case study for a dam reservoir in Iran in which, the impulse wave characteristics were available based on a numerical simulation using FUNWAVE model as a well-validated model. The similar range of accuracy was obtained in predicted values of impulse wave run-up for the studied real case.
