Coastal Overwash: Part 2, Upgrade to SBEACH

Abstract

This Coastal and Hydraulics Engineering Technical Note (CHETN) provides information about an improved capability to mathematically model overwash caused by elevated water elevation and wave runup. An upgrade to SBEACH (Storm-induced BEAch CHange Model, a numerical model for simulating storm-induced beach profile change) is described to simulate sediment transport and subaerial profile response by overwash associated with wave runup. The enhanced SBEACH model is validated with field data on overwash of protective dunes at Ocean City, MD, and overwash of the low and wide northern end of Assateague Island, MD. The new algorithm replaces that of Kraus and Wise (1993) previously employed in SBEACH.
