Process
| Describe processes represented by the model
|
Processes:
- Wave properties derived from wind speed, wind angle and equations that describe a "fully-developed" sea state.
- Longshore sediment transport as modeled by the CERC or Kamphuis formulas.
- Conservation of mass for sediment.
- Simple methods to model cross-shore sediment transport.
|
| 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.
|
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.

|
|
| 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.

Model description
| Model type:
|
Modular model for the coastal domain.
|
| 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.
