| | class="model_col1"| Model type:
| |
| | class="model_col2"| Modular model for the coastal domain.
| |
| |-
| |
| | class="model_col1"| Description:
| |
| | class="model_col2"| 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 ====
| |
| | |
| {| class="wikitable"
| |
| | class="model_col1"| Processes represented by model:
| |
| | class="model_col2"| (1) Wave properties derived from wind speed, wind angle and equations that describe a "fully-developed" sea state.<br>(2) Longshore sediment transport as modeled by the CERC or Kamphuis formulas.<br>(3) Conservation of mass for sediment.<br>(4) Simple methods to model cross-shore sediment transport.
| |
| |-
| |
| | class="model_col1"| Key physical parameters & equations:
| |
| | class="model_col2"| CERC formula for sediment transport rate (see Komar)
| |
| Kamphuis formula for sediment transport rate.<br>Conservation of sediment mass.
| |
| |-
| |
| | class="model_col1"| Length scale & resolution constraints:
| |
| | class="model_col2"| Spatial resolution of coastline is typically 1 to 50 meters.
| |
| |-
| |
| | class="model_col1"| Time scale & resolution constraints:
| |
| | class="model_col2"| The model is typically driven by hourly wind data (speed and angle) and models coastal change over a period of 10 to 100 years.
| |
| |-
| |
| | class="model_col1"| Numerical limitations and issues :
| |
| | class="model_col2"| The model cannot yet fully handle complex coastline geometries, such as those that cannot be represented (after rotation) by a single-valued function.

| ==== Testing ====
| |
| | |
| {| class="wikitable"
| |
| | class="model_col1"| Available calibration data sets:
| |
| | class="model_col2"| This model is not calibrated, but uses physically-based (measurable) parameters and measured data for validation. See next box.
| |
| |-
| |
| | class="model_col1"| Available test data sets:
| |
| | class="model_col2"| 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.
| |
| |-
| |
| | class="model_col1"| Ideal data for testing:
| |
| | class="model_col2"| High-resolution coastal change data, for example, digitized from aerial photography or measured with GPS.
