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.

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.
