Coastal shorelines are a key interface between terrestrial and aquatic ecosystems vital for human livelihood. As result, have experienced substantial modifications worldwide. Shoreline “hardening” – the construction of armor including seawalls, bulkheads, or rip-rap is common modification that has negative ecological effects. Currently, restoration involving removal replacement with “living” be...

Rivers of the Coastal Plain of the southeastern United States are characteristically low-gradient meandering systems that develop broad floodplains subjected to frequent and prolonged flooding. These floodplains support a relatively unique forested wetland (Bottomland Hardwoods), which have received considerable ecological study, but distinctly less hydrogeomorphic study. The hydroperiod, or an...

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...

The factors that influence the invasion of natural habitats by nonnative plants remain poorly understood. We investigated abiotic, biotic, and human influences on the distribution and abundance of nonnative species in coastal upland habitats of southern New England and adjacent New York, US. We censused vegetation and sampled soils in 776, 20 · 20 m plots in natural areas and constructed a spat...

The coastal zone represents varied and highly productive ecosystems such as mangroves, coral reefs, sea grasses and sand dunes. These ecosystems are under pressure on account of increased anthropogenic activity on the coast, as a result of globalisation. It is necessary to protect these coastal ecosystems to ensure sustainable development. This requires information on habitats, landforms, coast...

a B B o f J h w w Deposits of a transgressive-phase Lake Bonneville stillstand or scillation are found just below the elevation of the regressivehase Provo shoreline at numerous exposures throughout the onneville basin. Existence of these subProvo shoreline deposits rovides a new explanation for the massive size of Provo deposiional and erosional landforms, which can no longer be explained y a ...

The Antarctic Dry Valleys (ADV) are generally classified as a hyper-arid, cold-polar desert. The region has long been considered an important terrestrial analog for Mars because of its generally cold and dry climate and because it contains a suite of landforms at macro-, meso-, and microscales that closely resemble those occurring on the martian surface. The extreme hyperaridity of both Mars an...

The islands of northeast Fiji studied are all the emergent parts of the northern end of the Lau^Colville Ridge, a remnant island arc which has been rising for most of the Quaternary. Within the study area, investigations of coastal landforms (primarily emerged notches and shore platforms) and emerged coral reefs allow rates of tectonic movements to be calculated. The Vanuabalavu Island group is...
