| One-line model description | GENEralized model for SImulating Shoreline change |
| Extended model description | GENESIS calculates shoreline change produced by statial and temporal differences in longshore sand transport produced by breaking waves. The shoreline evolution portion of the numerical modeling system is based on one-line shoreline change theory, which assumes that the beach profile shape remains unchanged, allowing shoreline change to be described uniquely in terms of the translation of a single point (for example, Mean High Water shoreline) on the profile. |

| Process description model | |
|---|---|
| Describe processes represented by the model | GENESIS was designed to describe long-term trends of the beach plan shape in the course of its approach to an equilibrium form. The shoreline change model best calculates shoreline movement in transition from one equilibrium state to another. This change is usually caused by a notable pertubation, for example, jetty construction at a harbor or inlet, or placement of beach nourishment material. |
| Describe key physical parameters and equations | Breaking wave conditions are estimated from input wave information using linear wave theory. Longshore sand transport rates are estimated using a modified version of the CERC equation and the equation governing shoreline change is formulated by conservation of sand volume. |
| Describe length scale and resolution constraints | The longshore extent of the modeled reach can range from less than 1 mile to 10's of miles. |
| Describe time scale and resolution constraints | GENESIS is a long-term shoreline evolution model and is best applied to estimate shoreline change over time periods of 1 year to 10's of years. |
| Describe any numerical limitations and issues | Does not consider influence of cross-shore sand transport, not intended for short-term storm-induced shoreline change. No wave reflection from structures. No direct provision for changing tide level. |
| Model testing | |
|---|---|
| Describe available calibration data sets | No specific calibration data sets available. GENESIS has enjoyed many practical applications within the engineering and scientific community, results routinely published in proceedings of coastal conferences. |
