Because of the suitability of coastal lands for different groups of activities such as recreational, residential and commercial functions, there is an increasing demand among different stakeholders to benefit from these natural lands. The conflicts between the users, sometimes, lead to exclusiveness and limitation of public access to the shoreline. This article aims to recognize the main agents...

Recent attention has focused on the high rates of annual carbon sequestration in vegetated coastal ecosystems--marshes, mangroves, and seagrasses--that may be lost with habitat destruction ('conversion'). Relatively unappreciated, however, is that conversion of these coastal ecosystems also impacts very large pools of previously-sequestered carbon. Residing mostly in sediments, this 'blue carbo...

Land subsidence due to groundwater withdrawal combined with a global sea level rise creates a serious environmental problem in the coastal region. Groundwater withdrawal results in fluid pressure change in the layers. The pressure change in the layers induces both elastic and inelastic land compaction. The elastic compaction can be recovered if the water level rises again and inelastic compacti...

The exchange of groundwater between land and sea is a major component of the hydrological cycle. This exchange, called submarine groundwater discharge (SGD), is comprised of terrestrial water mixed with sea water that has infiltrated coastal aquifers. The composition of SGD differs from that predicted by simple mixing because biogeochemical reactions in the aquifer modify its chemistry. To emph...

This is a preliminary report on a project to characterize the historic species composition of coastal sage scrub vegetation in southern California using plot data collected between 1929 and 1934 by the USDA Forest Service's Vegetation Type Map (VTM) survey. Records and maps from a large historic data set collected for the VTM survey were converted into a digital database and GIS coverage. Histo...

Caspian Sea coastline in the Mazandaran province has been altered as a result of activities of developers attracted to aesthetic and coastal recreational aspects of forest ecosystems. Advances in GIS and RS techniques, has made it possible to study the coastal areas for better management. Hence, the present study was undertaken to determine land cover changes via applying cross classificat...

The beautiful coast of Kerala is as much a part of the unique dynamics of Kerala's social history as its natural history. The several ports on the coast facilitated commercial and cultural links of a population confined between the idyllic Western Ghats ranges and the Arabian Sea. These links extended to almost all the major ancient civilizations in the world. The fortuitous winds blowing over ...

Several analytical techniques used on both conventional colour photographs from SKYLAB and the LANDSAT MSS data in both photographic and magnetic digital tape fonnats provide useful sources of information about regional and seasonal patterns of stream sediment discharges along New Zealand coasts. The large area synoptic views from space are superior to aircraft photomosaics. The green visible b...

The goal of this project is to increase our understanding of the modification of complex atmospheric dynamics, cloudiness, and fog due to the interaction of the air, sea, and land in a coastal region. This increased understanding will lead to improvements in parameterizations of turbulence, cloudiness, and fog. In general, it will improve the episodic and seasonal forecasting of coastal weather...
