Because conventional markets value only certain goods or services in the ocean (e.g. fish), other services provided by coastal and marine ecosystems that are not priced, paid for, or stewarded tend to become degraded. In fact, the very capacity of an ecosystem to produce a valued good or service is often reduced because conventional markets value only certain goods and services, rather than the...
The visco-elastic properties of asphaltic layers make it appropriate for application in coastal protection in embankments. In this research, an experimental set up of a coastal embankment is developed to investigate the characteristics of lean stone asphalt layer on coastal embankments. More than 100 laboratory tests were carried out considering various loading conditions on the asphalt protect...
In this study, NASIR program is implemented to numerically simulate the temperature field near the intake/outlet of Paresar thermal power plant and assess the environmental provisions. According to low depth of coastal regions, two-dimensional depth-average governing equations and convection and temperature diffusion relationships are considered and solved by a finite volume method in NASIR pro...
Abstrac t Background and Objectives: pathogenic species of vibrio. It is a salt-requiring organism. It cases watery diarrhea often with abdominal cramping, nausea, vomiting and fever. This study was performed to assess the seawater samples of Caspian coastal regions. Vibrio parahaemolyticus is one of Materials and methods: APW and TCBS agar media and then biochemistry t...
Marine and coastal tourism is one of the fastest growing areas within the world’s largest industry. Yet despite increased awareness of the economic and environmental significance of marine and coastal tourism it is only in recent years that a substantial body of research has emerged. This article provides a review of some of the coastal and marine tourism literature which focuses, in particular...
The 26 December 2004 Indian Ocean tsunami had major effects on coastal communities and ecosystems. An assessment of coastlines after the tsunami indicates that coastal vegetation such as mangroves and beach forests helped to provide protection and reduce effects on adjacent communities. In recent years, mangroves and other coastal vegetation have been cleared or degraded along many coastlines, ...
This report summarizes the major findings of a United States Geological Survey (USGS)-funded project entitled the "West-Central Florida Coastal Studies Project" and managed by the USGS Center for Coastal Geology and Regional Marine Studies in St. Petersburg, FL. USGS scientists from Woods Hole and Menlo Park were involved as well. This project was a co-operative five-year venture with scientist...
Aim Recently discovered deep phylogenetic gaps in coastal California marine taxa are geographically discordant with the provincial biogeographic boundary at Point Conception. This discordance runs contrary to the phylogeographic hypotheses that were derived from studies of coastal marine taxa in south-eastern North America. Here, I investigate the nature of the discrepant phylogeographic and bi...
the management and analysis of flood hazards is of great socio- economic and ecological importance as it was estimated that 50 percent of word’s population resides and works within the costal zone till 2030. the management of coastal flood hazard reflects the cumulative effects and criteria more than the human mind can handle effectively. the flood management requires decision making for rela...
It is highly likely that coastal erosion due to long-term sea level rise associated with global warming will have a significant impact on Australia’s coastal systems, and any associated infrastructure, over the next century. Long-term coastal erosion is thought to occur largely through sudden-onset storm events. Therefore, attempting to quantify this natural hazard is critical to future develop...
