Metadata

Also known as
Model type Single
Model part of larger framework
Spatial dimensions 1.5D
Spatial extent
Model domain Coastal
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.
Keywords:

Describe processes represented by the model Processes:
  1. Wave properties derived from wind speed, wind angle and equations that describe a "fully-developed" sea state.
  2. Longshore sediment transport as modeled by the CERC or Kamphuis formulas.
  3. Conservation of mass for sediment.
  4. 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
