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.

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.

Do you have current or future plans for collaborating with other researchers?	Have collaborated somewhat with Brad Murray and Andrew Ashton.

Is there a manual available?	No
