Water-at-Rest Equilibrium Stability Analysis of a first-moment Shallow Water Exner Moment Model with Sediment Entrainment and Deposition: Extended Technical Report
SWEMED1 has a weakly hyperbolic fully-settled water-at-rest equilibrium without indicated instability; fast-limit scaling produces a suspended equilibrium still weakly hyperbolic due to transport closure.
