SBEACH: Numerical Model for Simulating Storm-Induced Beach Change. Report 4.Cross-Shore Transport Under Random Waves and Model Validation with SUPERTANK and Field Data

摘要

Beach erode and accrete in response to varying waves, water levels, and currentsin the nearshore zone. Protection of upland infrastructure is a primary concern of coastal engineering. recent years. Numerical modeling of beach evolution can be applied to assist in project design. Numerical models provide a framework for predicting project response, objectively evaluating design alternatives and analyzing data to develop an understanding of coastal processes. The Storm-induced BEAch CHange (SBEACH) numerical model is an engineering tool for simulating beach profile evolution in response to storms. This report describes recent model enhancements developed to improve calculation of sediment transport under random waves. A comprehensive evaluation of model capabilities in predicting beach and dune erosion is presented using high-quality laboratory and field data of beach profile change.
