A GIS TOOL FOR ANALYSIS AND INTERPRETATION OF COASTAL EROSION MODEL OUTPUTS (SCAPEGIS)

摘要

The SCAPE (Soft Cliff and Platform Erosion) model of cliff toe retreat, and a cliff-top recession model, have been linked with a new flexible GIS tool (SCAPEGIS) to provide visualisation and analytical capability for the model results. 45 model runs exploring different sealevel rise and wave climate scenarios and protection choices are available. Outputs are available in the form of maps, dynamic visualisation, and descriptive statistics of key parameters such as cliff toe and cliff top position. It also allows analysis with other datasets such as land use and building location for impact evaluation, and hence supports shoreline management and cliff-top land use planning. Some preliminary results and ideas for further development are presented.
