AB: NearCoM, the NOPP-supported Nearshore Community Model, is a modeling system linking together advanced scientific models for simulating the high spatial and temporal variability of nearshore processes. One model slated for inclusion in the modeling system is REFDIF-SNL, a fully dispersive, weakly nonlinear frequency domain model essentially representing a nonlinear extension of the mild slope equation commonly used in nearshore wave propagation problems. In this study we discuss some potential uses of the model, particularly in support of sediment transport calculations. We further discuss some implemented and planned improvements to the model, designed to increase model utility and performance without sacrificing physical fidelity. In particular, we investigate the efficacy of using recently-developed spectral parameterizations to represent the evolution of the high frequency spectral tail in nearshore wave transformations.
