Book Description
Beach erode and accrete in response to varying waves, water levels, and currents in the nearshore zone. During storms beach and dune erosion can occur quickly, causing shoreline recession and damage to property and upland resources. Hence, protection of upland infrastructure is a primary concern of coastal engineering. Beach nourishment is a preferred method of providing such protection, and many beach-fill projects have been designed and constructed in recent years. Design of such fills requires an understanding of and the capability to predict sediment transport processes that control beach response to storms. 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, the fourth in a series describing the development of SBEACH, 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.

Book Description
This report provides guidance for implementing SBEACH, the Storm- Induced BEAch CHange model, via a user interface available for the personal computer. SBEACH simulates beach profile change, including the formation and movement of major morphologic features such as longshore bars, troughs, and berms, under varying storm waves and water levels. The personal computer version of SBEACH is accessed through a user interface which facilitates data entry and manipulation, graphical representation of input and output, and execution of the model. The interface also provides considerable error and range checking prior to actual running of the model. The first two chapters of the report present information about applying the model, including hardware requirements, loading SBEACH onto a hard disk, discussion of the interface structure through which the numerical model is operated, and guidance for model calibration. The final chapter is written as a tutorial, guiding the user in installing, running, and working through several example simulations.

Book Description
The SBEACH (Storm-induced BEAch CHange) numerical simulation model was developed at the U.S. Army Engineer Waterways Experiment Station to calculate beach and dune erosion under storm water levels and wave action. The work documented in this report was performed to allow SBEACH to account for nonerodible (hard) bottoms in computing dune and beach erosion. Sensitivity tests were used to evaluate the results of incorporating the HB factor into SBEACH. For qualitative reasonability of results, addition of the HB factor was found to perform well. Quantitative tests comparing a single available case of HB exposure in a large wave tank with several tests performed with a mid-scale physical model were also successful. Comparisons with the mid-scale tests also validated the monochromatic and random-wave transport calculations. For comparison with the mid-scale tests, a scaling criterion was derived; success in reproducing the physical model results with SBEACH is an indirect confirmation that the basic physical principles acting to produce storm-induced beach erosion are represented in the numerical model.
