A Boussinesq type extension of the GeoClaw model - a study of wave breaking phenomena applying dispersive long wave models

Kim, Jihwan; Pedersen, Geir Kleivstul; Løvholt, Finn; LeVeque, Randall J. (Peer reviewed; Journal article, 2017)

The nonlinear shallow water model is widely used in the study of tsunami propagation, but an increasing number of studies are dedicated to the dispersion dynamics of tsunamis. If the wave dispersion becomes important, ...

Accounting for Uncertainty and Variability in Geotechnical Characterization of Offshore Sites

Farrokh, Nadim (Chapter, 2015)

A climatic trigger for the giant Troll pockmark field in the northern North Sea

Mazzini, Adriano; Svensen, Henrik; Forsberg, Carl Fredrik; Linge, Henriette; Lauritzen, Stein-Erik; Haflidason, Haflidi; Hammer, Øyvind; Planke, Sverre; Tjelta, Tor-Inge (Journal article; Peer reviewed, 2017)

Pockmarks are seafloor craters usually formed during methane release on continental margins. However, the mechanisms behind their formation and dynamics remain elusive. Here we report detailed investigations on one of the ...

A Constitutive Model for Soft Clays Incorporating Elastic and Plastic Cross-Anisotropy

Castro, Jorge; Sivasithamparam, Nallathamby (Peer reviewed; Journal article, 2017)

Natural clays exhibit a significant degree of anisotropy in their fabric, which initially is derived from the shape of the clay platelets, deposition process and one-dimensional consolidation. Various authors have proposed ...
