This paper presents a new, generalized two‐phase debris flow model that includes many
essential physical phenomena. The model employs the Mohr‐Coulomb plasticity for the …

Interacting massive spin-1 fields have been widely used in cosmology and particle physics.
We obtain a new condition on the validity of the classical limit of these theories related to the …

We present a nonhydrostatic ocean model with an isopycnal (density-following) vertical
coordinate system. The primary motivation for the model is the proper treatment of …

A mountain disaster chain is a complex system that consists of several sub-disasters and
can result in high casualties or serious economic loss. In this study of the mountain disaster …

This paper deals with the development of efficient incomplete multidimensional Riemann
solvers for hyperbolic systems. Departing from a four-waves model for the speeds of …

We develop fifth-order A-WENO finite-difference schemes based on the path-conservative
central-upwind method for nonconservative one-and two-dimensional hyperbolic systems of …

The key goals to studying submarine landslides and associated tsunamis are to better
assess the magnitude information of palaeo-tsunamis and to contribute to assessing future …

Tailings dam breach modelling studies have received considerable attention recently due to
the rise in the number of tailings dam failures and catastrophic consequences caused by …

This paper focus on the numerical approximation of two-layer shallow water system. First, a
new approximation of the eigenvalues of the system is proposed, which satisfies some …

This paper develops high-order accurate well-balanced (WB) energy stable (ES) finite
difference schemes for multi-layer (the number of layers M⩾ 2) shallow water equations …
