Abstract
  • With the current pressure for increased growth, the affects of climatic forcing events pose serious threats to Oregon's Coastal Communities. Mathematical methods have been implemented to establish setback distances for development adjacent to littoral cells. Using formulae developed by the Coastal Construction Setback Taskforce (CCST) under the Oregon Coastal Management Plan (OCMP), this research paper presents and demonstrates a computerized geographic information system (GIS) model for the dynamic delineation of chronic coastal hazard zones (CCHZs) along an Oregon dune backed beach. The model's required inputs are limited to widely available NOAA wave data and general shoreline survey information. The model and GIS interface have the potential to provide non-technically trained coastal managers with a tool for calculating and displaying a CCHZ on a site specific, storm-by-storm basis. The development of a computer application for the modeling of spatial CCHZs using geo-spatial analysis tools represents both a significant contribution to coastal hazard studies and coastal community planning.
