| One-line model description | Numerical Model for Simulating Storm-Induce Beach Change |
| Extended model description | SBEACH is a numerical simulation model for predicting beach, berm, and dune erosion due to storm waves and water levels. It has potential for many applications in the coastal environment, and has been used to determine the fate of proposed beach fill alternatives under storm conditions and to compare the performance of different beach fill cross-sectional designs. |

| Process description model | |
|---|---|
| Describe processes represented by the model | SBEACH is an empirically based numerical model for estimating beach and dune erosion due to storm waves and water levels. The magnitude of cross-shore sand transport is empirically related wave energy dissipation per unit water volume in the main portion of the surf zone. Direction of transport is dependent on deep water wave steepness and sediment fall speed. |
| Describe key physical parameters and equations | See SBEACH documentation (http://chl.erdc.usace.army.mil/chl.aspx?p=s&a=Software;31 ). |
| Describe length scale and resolution constraints | SBEACH is a beach profile evolution model. The model domain should extend from the landward limit of wave run-up offshore to the depth of closure. |
| Describe time scale and resolution constraints | SBEACH is a short-term storm processes model and is intended for the estimation of beach profile response to storm events. Typical simulation durations are limited to hours to days (1 week maximum). |
| Describe any numerical limitations and issues | SBEACH is an empirically based model that was developed for sandy beaches with uniform representative grain sized in the range of 0.2 to 0.42 mm. SBEACH should be tested or calibrated using data from beach profile surveyed before and after storms on the project coast. |
| Model testing | |
|---|---|
| Describe available calibration data sets | SBEACH was "validated" using a large suite of laboratory and field data sets. See SBEACH Report 4: Cross-Shore Transport Under Random Waves and Model Validation with SUPERTANK and Field Data. http://chl.erdc.usace.army.mil/chl.aspx?p=s&a=Software;31 |
