Extraction of Beach Landforms from DEMs using a Coastal Management Expert System
نویسندگان
چکیده
This paper describes the use of a prototype coastal management expert system, to facilitate the extraction of a salient element of coastal landforms from a DEM derived from stereo aerial photography. The system, COAMES (COAstal Management Expert System), is currently under development at Plymouth Marine Laboratory and the University of Plymouth. The sub-landform to be extracted is identified and isolated through use of “intelligent” ground control points stored within COAMES’ object-oriented data structure, in conjunction with geomorphological rules and functions embedded in COAMES’ hierarchical knowledge structure. The morphology of this extracted feature is modelled using polynomial functions this can be compared with a similar feature extracted at a different time to gain a picture of geomorphic feature development.

of a thesis at the University of Miami. Coastal Erosion poses a significant threat to several coastal communities in Florida. Ecosystem managers are tasked with both protecting the community from storm events and preserving the natural ecosystems found in the coastal zone. The most widely utilized method for shoreline protection in Florida is beach renourishment. Beach renourishment projects ar...

Extended abstract 1- Introduction Coastal environments are one of the most sensitive environmental systems under the influence of dominant hydrodynamic processes. Coastal changes and evolution are occurring very fast. Coastal areas are now gradually becoming known as severe natural and man-made disturbances, including sea levels rising, coastal erosion and sedimentation, and over-exploitat...
متن کاملGeomorphic Analysis in Determining Coastal Cells and Its Role in Coastal Management (Case Study: Bandar Anzali to Chalous Coasts)
Introduction Due to the different geomorphological and morph dynamic forces of the coastal area, they form different areas. Each of these areas requires its own coastal management. While in our country, coastal management is done without considering the characteristics and coastal characteristics of each coast. In this study, in order to classify coasts and determine coastal cells, morph dynam...
