SMS:GenCade Model Control Dialog

The Gencade Model Control dialog is used to set beach conditions, lateral boundary conditions and general simulation options. This document highlights the more commonly used options. Refer to the GenCade web site for a more detailed description of how these parameters affect the model results.
