the “driving force - pressure - state - impact – response” modeling framework isadopted to consider the formation mechanisms of environmental risks and the requirements ofecological environment protection. moreover, a systematical index system and evaluation model forthe measurement of the coastal ecological security level is put forward in this paper to assess thestate of coastal ecological en...

Sea level rise is often associated with climate change and global warming. The in shoreline a continuous process that occurs through various processes such as erosion, sedimentation, sea rise, wave behaviour land use. Rapid technological advancement has made it possible to quickly identify the changes combination of Geographical Information Systems (GIS) application Remote Sensing technology. c...

Background and Objectives: Coastal physical vulnerability studies were first conducted by Gornitz in 1991 on the west coast of Atlantic Ocean, have since been studied extensively other parts world. In this article, determining severity Sefidrood delta coast, identifying coastal landforms how they deform over time are main objectives research. Methods: By using results field monitoring, interpre...

introduction a considerable percentage of the world’s population is living in the coastal areas. thus, there are many different kinds of problems in these regions. because of the large amount of the people in these areas, their ecosystems are confronted with huge and serious problems. there are different types of arrangements for preventing destruction of ecosystems around the seas. unified man...

An important problem in the study of microparticles in the marine environment, suspended in the water column or deposited as sediment on the ocean bottom, is the determination of provenance of the microparticles-where did they come from and by what processes were they transported to the sampling location? Two techniques of possible interest to those concerned with tracing the origins and disper...

Bathymetry is the science to study and measure depths of ocean floor. The differences in water depth, underwater slope floor structure were investigated using a geographic information system (GIS). This article investigates changes hydrodynamic sedimentation processes Saldanha Bay as result harbour constructions that took place early 1970s. construction included massive dredging operations resu...

Coastal ecosystems are increasingly threatened by eutrophication and dystrophy. In this context, the full pattern of a bloom dominated dinoflagellate, Lepidodinium chlorophorum, was investigated high frequency monitoring buoy equipped with sensors allowing nutrients photosynthesis measurements. An increase N/P ratio affected phytoplankton physiology leading to collapse slight oxygen depletion. ...

Increased coastal human intervention and climate change are leading to rapid changes in areas often causing catastrophic damage resident populations. The ShorelineS model was introduced, which can explain drastic beach were simulated. According the modeling results, installation of Gungchon Port caused sedimentation south port. It reviewed that erosion tendency is changed after breakwater front...

sensitive coastal areas are fragile ecosystems affected by geographic features and in the same time settlements were developed around these areas due to their ecological capability. coastal ecosystems due to their countless benefits are very important for protection. hence, this paper attempts to determine the sensitivity of coastal ecosystem to disturbances in hormozgan province. we reviewed 2...
