GenCade:Basic Assumptions

__NOTITLE__

Basic Assumptions

Because GenCade is a one-line model, it is constrained by the standard assumptions upon which this type of model is based:

• The beach profile shape remains constant
• The shoreward and seaward depth limits of the profile are constant
• Sand is transported alongshore by the action of breaking waves and longshore currents
• The detailed structure of the nearshore circulation is ignored
• There is a long-term trend in shoreline evolution
