| One-line model description | Coastal evolution model |
| Extended model description | Shoreline is a "line model" for modeling the evolution of a coastline as the result of wind/wave-driven longshore sediment transport. It is based on conservation of mass and a semi-empirical sediment transport formula known as the CERC formula. This model was specifically adapted for modeling the evolution of the coastline near Barrow, Alaska. |

| Process description model | |
|---|---|
| Describe processes represented by the model | Processes:
|
| Describe key physical parameters and equations | CERC formula for sediment transport rate (see Komar)
Kamphuis formula for sediment transport rate. Conservation of sediment mass. |
| Describe length scale and resolution constraints | Spatial resolution of coastline is typically 1 to 50 meters. |
| Describe time scale and resolution constraints | The model is typically driven by hourly wind data (speed and angle) and models coastal change over a period of 10 to 100 years. |
| Describe any numerical limitations and issues | The model cannot yet fully handle complex coastline geometries, such as those that cannot be represented (after rotation) by a single-valued function. |
| Model testing | |
|---|---|
| Describe available calibration data sets | This model is not calibrated, but uses physically-based (measurable) parameters and measured data for validation. See next box. |
| Upload calibration data sets if available: | |
| Describe available test data sets | Model was only used for modeling coastline change in the vicinity of Barrow, Alaska. Hourly wind data from a met station at the Barrow Airport was used to drive the model. High-resolution coastline data digitized from aerial photos by Manley et al. (2006) was used for initial and final coastlines. The latter was used for validation purposes. High-resolution DEMs were also used. |
| Upload test data sets if available: | |
| Describe ideal data for testing | High-resolution coastal change data, for example, digitized from aerial photography or measured with GPS. |
