The economic growth of aquaculture and the dependence of a large growing population on coastal resources have led to coastal degradation and reduced resources. In this paper while realizing the potential capacities of the island systems,  the aquaculture activities of the island are specially discussed  in the framework of Integrated Coastal Zone Management (ICZM). Therefore, in this study, fir...

From catastrophic natural disasters to the threats our college students face, there has been a heightened demand for Mass Notification Systems (MNS) that provide clear, concise and intelligible voice messages that communicate how people should respond in an emergency. Manmade or natural, the magnitude and diversity of today’s threats have influenced the federal government and other organization...

one of the most important natural factors and critical facilities in tehran is presence of alborzslopes river-valleys which have been considered as natural tourist places for citizens since a long time ago, especiallyin hot summers and play effective role in creating a balance between manmade and natural spaces. importance ofthese river-valleys as ecological pathways is enhanced with the increa...

the volume and surface area of the coast is a function of basin water levels. recognizing the factors of coastal geomorphologic changes could have a pivotal role in planning and managing the coast. effective factors in the formation and evolution of geomorphologic factors such as geological, tectonic, paleoclimatic, paleoclimatic and sea level changes have been considered in this study and the ...

The prevalent human hantavirus disease in Sweden is nephropathia epidemica, which is caused by Puumala virus and shed by infected bank voles (Clethrionomys glareolus). To evaluate temporal and spatial patterns of this disease, we studied 2,468 reported cases from a highly disease-endemic region in northern Sweden. We found that, in particular, middle-aged men living in rural dwellings near coas...

The world’s largest deltas are densely populated, of significant economic importance and among the most valuable coastal ecosystems. Projected twenty-first century sea-level rise (SLR) poses a threat to these low-lying coastal environments with inhabitants, resources and ecology becoming increasingly vulnerable to flooding. Large spatial differences exist in the parameters shaping the world’s d...

1-Introduction The location of shorelines and the state of their changes in the past, present and over time are important for scientists, engineers and managers. For example, analyzing shoreline information for coastal protection design, policy development, updating and reviewing numerical models, assessing sea level rise, developing risk areas for coastal development, achieving the definition...

both climate change and anthropogenic impact are creating a dynamic of continuous changes in ecosystems. while the expected consequences of these changes are global, the occurrence of extreme events and specific environmental problems are usually local or regional phenomenon. in particular, the coastal ecosystems are among the first vulnerable areas to show those changes; in spite of this, are ...
