Are We Protecting the Beneficial Functions of Coastal Landforms? an Analysis of Activities Permitted on Coastal Landforms on Cape Cod in 1999
Chesapeake Bay, the Nation’s largest estuary, has been adversely impacted by excess nutrients. Excess nutrients have caused low dissolved oxygen levels leading to loss of fisheries and other living resources. The Chesapeake Bay Program (CBP) is leading an effort to reduce nutrient sources and loads in the Bay watershed to meet dissolved oxygen criteria in the Bay by 2010. The U.S. Geological Su...
متن کاملCoastal landforms and accumulation of mangrove peat increase carbon sequestration and storage.
Given their relatively small area, mangroves and their organic sediments are of disproportionate importance to global carbon sequestration and carbon storage. Peat deposition and preservation allows some mangroves to accrete vertically and keep pace with sea-level rise by growing on their own root remains. In this study we show that mangroves in desert inlets in the coasts of the Baja Californi...
متن کاملExtraction of Beach Landforms from DEMs using a Coastal Management Expert System
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 an...
متن کاملTowards an Ontology of Landforms
The paper begins with the question “Do mountains exist?” It shows that providing an answer to this question is surprisingly difficult, and that the answer which one gives depends on the context in which the question is posed. Mountains clearly exist as real correlates of everyday human thought and action, and they form the archetype for geographic objects. Yet individual mountains lack many of ...
متن کاملModelling cockpit karst landforms
The purpose of this article is to present a model of the formation processes of cockpit karst landscapes. The CHILD software was used to simulate landscape evolution including dissolution processes of carbonate rocks. After examining briefly how the CHILD model operates, two applications of this model involving dissolution of carbonate rocks are presented. The simulated landscapes are compared ...
