Preliminary hydrodynamic analysis of landslide-generated waves in Tidal Inlet, Glacier Bay National Park, Alaska

A landslide block perched on the northern wall of Tidal Inlet, Glacier Bay National Park (Figure 1), has the potential to generate large waves in Tidal Inlet and the western arm of Glacier Bay if it were to fail catastrophically. Landslide-generated waves are a particular concern for cruise ships transiting through Glacier Bay on a daily basis during the summer months. The objective of this study is to estimate the range of wave amplitudes and periods in the western arm of Glacier Bay from a catastrophic landslide in Tidal Inlet. This study draws upon preliminary findings of a field survey by Wieczorek et al. (2003), and evaluates the effects of variations in landslide source parameters on the wave characteristics.

Landslide triggers and types

The term “landslide trigger” refers to an external stimulus, such as intense rainfall, rapid snowmelt, seismic shaking, volcanic eruption, stream/coastal erosion, or natural dam failure, which causes an immediate or near-immediate response in the form of landslide activity. In this paper, we discuss the types of landslides caused by these triggering processes and present a limited number of worldwide examples of their occurrence.
