H.-H. Liu, R. Salve, J.-S. Wang, G.S. Bodvarsson, D. Hudson
2004, Journal of Contaminant Hydrology (74) 39-59
Results of a fault test performed in the unsaturated zone of Yucca Mountain, Nevada, were analyzed using a three-dimensional numerical model. The fault was explicitly represented as a discrete feature and the surrounding rock was treated as a dual-continuum (fracture-matrix) system. Model calibration against seepage and water-travel-velocity data suggests that...
Numerical analysis of the mobility of the Palos Verdes debris avalanche, California, and its implication for the generation of tsunamis
J. Locat, H.J. Lee, P. Locat, J. Imran
2004, Conference Paper, Marine Geology
Analysis of morphology, failure and post-failure stages of the Palos Verdes debris avalanche reveals that it may have triggered a significant tsunami wave. Our analysis of the failure itself indicates that the slope is stable under aseismic conditions but that a major earthquake (with a magnitude around 7) could have...
