{{Model identity | |||
|Model type=Single | |||
|Categories=Coastal | |||
|Spatial dimensions=1.5D | |||
|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: | |||
# 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. | |||
}} | |||
{{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. | |||
|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. | |||
|Describe ideal data for testing=High-resolution coastal change data, for example, digitized from aerial photography or measured with GPS. | |||
