When checking the behaviour of large landslides, deterministic stability analysis has little sense. Stability coefficients can only be seen as the relationship between acting and reacting forces. In fact, large landslides simply move in any case, more or less quickly. When stable, the displacements are actually so small that they aren't detectable. Thus the so called security factor could always be set to unity, and the computations performed as back analysis. The transition from a very slow viscous displacement to a catastrophic failure is better described in a change of rheological behaviour than in an overtaking of a stability coefficient. …
A Hydrodynamics Perspective For The 2004 Megatsunami, Costas E. Synolakis
A Hydrodynamics Perspective For The 2004 Megatsunami, Costas E. Synolakis
Geohazards
The megatsunami of 26 December 2004 was the first tsunami with transoceanic impact since the 1960 Great Chilean and 1964 Great Alaskan tsunamis. Because of the distribution of deaths among a large portion of the nations of the world, the 2004 Boxing Day tsunami is the first universal natural disaster of modern times. For the purpose of adequate mitigation of future tsunamis, it is important to understand which factors control most critically the final characteristics of the flooding, namely runup and inundation. Their successful modeling requires not only a credible database of inundation parameters, against which models can be tested …

Analysis, Modeling, And Simulation Of The Tides In The Loxahatchee River Estuary (Southeastern Florida)., Peter Bacopoulos
Electronic Theses and Dissertations
Recent cooperative efforts between the University of Central Florida, the Florida Department of Environmental Protection, and the South Florida Water Management District explore the development of a two-dimensional, depth-integrated tidal model for the Loxahatchee River estuary (Southeastern Florida). Employing a large-domain approach (i.e., the Western North Atlantic Tidal model domain), two-dimensional tidal flows within the Loxahatchee River estuary are reproduced to provide: 1) recommendations for the domain extent of an integrated, surface/groundwater, three-dimensional model; 2) nearshore, harmonically decomposed, tidal elevation boundary conditions. Tidal simulations are performed using a two-dimensional, depth-integrated, finite element-based code for coastal and ocean circulation, ADCIRC-2DDI. Multiple …
