    • High-resolution finite volume methods for dusty gas jets and plumes 

      Pelanti, Marcia; LeVeque, Randall J., 1955- (2006)
      We consider a model for dusty gas flow that consists of the compressible Euler equations for the gas coupled to a similar (but pressureless) system of equations for the mass, momentum, and energy of the dust. These sets ...
    • High-resolution rotated grid method for conservation laws with embedded geometries 

      Helzel, Christiane, 1971-; Berger, Marsha J.; LeVeque, Randall J., 1955- (2005)
      We develop a second-order rotated grid method for the approximation of time dependent solutions of conservation laws in complex geometry using an underlying Cartesian grid. Stability for time steps adequate for the ...
    • Probabilistic Tsunami Hazard Assessment (PTHA) for Crescent City, CA. Final Report for Phase I 

      Gonzalez, Frank I.; LeVeque, Randall J., 1955-; Adams, Loyce M. (University of Washington Department of Applied Mathmatics, 2013-02-02)
      This demonstration Probabilistic Tsunami Hazard Assessment (PTHA) study of Crescent City, California was funded by BakerAECOM and motivated by FEMA's desire to explore methods to improve products of the FEMA Risk Mapping, ...
    • Tsunami Hazard Assessment of the Strait of Juan de Fuca 

      Gonzalez, Frank I.; LeVeque, Randall J.; Adams, Loyce M. (2015-09-24)
      This report documents the results of a study supported by the Washington State Emergency Management Division of the tsunami hazard along the Strait of Juan de Fuca. Results include inundation depths and times of arrival ...
    • A wave propagation algorithm for hyperbolic systems on curved manifolds 

      Rossmanith, James A.; Bale, Derek S.; LeVeque, Randall J., 1955- (Elsevier, 2004-09-20)
      An extension of the wave propagation algorithm first introduced by LeVeque [J. Comput. Phys. 131 (1997) 327] is developed for hyperbolic systems on a general curved manifold. This extension is important in a variety of ...
    • A Wave Propagation Method for Conservation Laws and Balance Laws with Spatially Varying Flux Functions 

      LeVeque, Randall J., 1955-; Bale, Derek S.; Mitran, Sorin; Rossmanith, James A. (Society for Industrial and Applied Mathematics, 2002)
      We study a general approach to solving conservation laws of the form qt+f(q,x)x=0, where the flux function f(q,x) has explicit spatial variation. Finite-volume methods are used in which the flux is discretized spatially, ...
    • A wave propagation method for three-dimensional hyperbolic conservation laws 

      Langseth, Jan Olav; LeVeque, Randall J., 1955- (Elsevier, 2000-11-20)
      A class of wave propagation algorithms for three-dimensional conservation laws and other hyperbolic systems is developed. These unsplit finite-volume methods are based on solving one-dimensional Riemann problems at the ...
