Prognostic variables for this solver are column mass of dry air (mu), velocities u, v and w (vertical velocity), potential temperature, and geopotential. Non-conserved variables (e.g. temperature, pressure, density) are diagnosed from the conserved prognostic variables. The solver uses a third-order Runge-Kutta time-integration scheme coupled with a split-explicit 2nd-order time integration scheme for the acoustic and gravity-wave modes. 5th-order upwind-biased advection operators are used in the fully conservative flux divergence integration; 2nd-6th order schemes are run-time selectable.6th order schemes are run-time selectable.)

  • Model:CEM  + (The evolution of the coastline is governedThe evolution of the coastline is governed by a continuity equation; the rate of horizontal shoreline change in the local cross-shore direction is proportional to the divergence of alongshore sediment flux. Alongshore sediment transport is computed via the common CERC formula, which relates alongshore sediment flux to breaking-wave approach angle and breaking wave height. Breaking-wave characteristics in each shoreline location are calculated by starting with the deep-water height and propagation direction (obtained for each time slice from the input wave file), and refracting and shoaling the waves over assumed shore-parallel contours until breaking occurs. The CERC equation also involves an empirical constant K, which can be configured by the model user. Other equations for sediment flux can easily be substituted. See Ashton and Murray (2006a) for details.See Ashton and Murray (2006a) for details.)

  • Model:Quad  + (The key physical parameters are: (1) the sThe key physical parameters are: (1) the sediment unit-flux, defined as the sediment input from the river network in units of volume per unit width. (2) The average water discharge per unit width. (3) The basement slope on top of which the delta develops. (4) The base-level curve. </br></br>The key equations are a sediment mass balance and the boundary conditions dictated by diffusive transport (i.e., the sediment flux is proportional to the local bed slope through the fluvial diffusivity). To first order calculations, we assume the fluvial diffusivity to be half the water discharge per unit width (they both have the same units). More accurate expressions for the fluvial diffusivity can be found in Paola 2000 and Lorenzo-Trueba et al.2009. Paola 2000 and Lorenzo-Trueba et al.2009.)

  • Model:PyDeCe  + (The pyroclastic flow is treated as a two-cThe pyroclastic flow is treated as a two-component granular flow with >30% volume fraction of solids supported by excess pore fluid pressure in a laminar Newtonian fluid. This approach of modeling mass flows is adapted from the debris flow model of Iverson and Denlinger (2001). The model solves depth averaged mass and momentum conservation equations in 2D, with suitable source terms, to determine the thickness and velocity of the current at each point in time and space. The current is primarily driven by gravity and the motion of the current is opposed by friction and viscous resistance. A shear-rate dependent variable basal friction model is used to determine the basal friction as the flow evolves (Jop et al., 2006). A 1st order Godunov scheme with an HLLC Riemann solver is used to calculate the flux across cell interfaces (Toro, 2009) and the source terms are solved separately using an explicit Euler method.ed separately using an explicit Euler method.)
