Abstract

A model for tracking a shoreline in a subsiding ocean basin is introduced, a problem that can be posed as a generalized Stefan melting problem where the latent heat term is a function of space and time. An enthalpy-like formulation for the shoreline problem is constructed and a fixe-grid solution is developed and verified by comparison to an available analytical solution. The advantage of the fixed-grid is exploited by tracking a two-dimensional shoreline advancing into an ocean basin. Predictions show that features in the moving shoreline reach a stable configuration that mirrors the nature of the imposed basement topology.
