The climate changes in recent years in the southern Baltic have been resulting in an increased frequency of natural extreme phenomena (i.e. storms, floods) and intensification of abrasion processes, which leads to introduction of large amounts of sedimentary deposits into the marine environment. The aim of this study was to determine the mercury load introduced to the Baltic Sea with deposits c...

some researchers believe that because of the severe earthquake and tsunami in the fourth century h., a large part of siraf submerged by the persian gulf water fluctuations. based on the available evidence and also by the archaeological survey of the siraf coastal surrounding areas, the author argues that despite the devastating earthquake occurred to destroy much of the coastal architectural st...

We evaluated the impact of shoreline dynamics on fringing vegetation density at mid- and low-marsh elevations at a high-energy site in the northern Gulf of Mexico. Particularly, we selected eight unprotected shoreline stretches (75 m each) at a historically eroding site and measured their inter-annual lateral movement rate using the DSAS method for three consecutive years. We observed high inte...

This paper reports on research that aims to develop a technique for rapidly monitoring coastal erosion over wide areas, by deriving synergy from three integrated measurement technologies. These technologies are the global positioning system (GPS), automated digital photogrammetry using imagery acquired with a small format digital camera, and synthetic aperture radar interferometry (InSAR). The ...

Estimates of sediment concentrations and flux in coastal oceans can help predict optical and acoustical water properties, interpret remotely sensed coastal data, and characterize seafloor morphology. Predicting turbidity requires that we account for processes that erode, supply, and redistribute sediment; including storms, floods, winds, tides, and energetic waves. In many environments, particu...

The relative contributions of sea-level rise (SLR) and increasing extratropical storminess to the frequency with which waves attack coastal features is assessed with a simple total water level (TWL) model. For the coast of the U.S. Pacific Northwest over the period of wavebuoy observations (approximately 30 years), wave height (and period) increases have had a more significant role in the incre...

Developed coastal areas often exhibit a strong systemic coupling between shoreline dynamics and economic dynamics. “Beach nourishment”, a common erosion-control practice, involves mechanically depositing sediment from outside the local littoral system onto an actively eroding shoreline to alter shoreline morphology. Natural sedimenttransport processes quickly rework the newly engineered beach, ...

A simple total water level (TWL) model is employed to investigate the relative importance of various climate controls on the potential for an increased probability of coastal erosion and flooding on sandy beaches of the US Pacific Northwest. Model results suggest that if decadal-scale increases in storm intensity (wave height) continue into the future, this process will have a greater impact on...

Coastal dunes protect low lying coastal areas against the sea. Extreme waves and water levels during severe storms may cause breaching of the dunes. Consequently, serious damage due to flooding and direct wave attack could occur, resulting in loss of life and property. Proper coastal management implies that reinforcement measures will be taken if the actual safety level does not meet the agreed...
