Novel Model for Manoeuvrability of Ships Advancing in Landslide-Generated Tsunamis

open access: yesAdvances in Civil Engineering, 2020
The rock and soil on the shore of the bank are unsteady and slide in a poor environment, affecting the water body in the river channel and forming landslide-generated tsunamis. This directly impacts the navigation of vessels in the river.
