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...
Spatial data acquisition is a critical process for the identification of the coastline and coastal zones for scientists involved in the study of coastal morphology. The availability of very high-resolution digital surface models (DSMs) and orthophoto maps is of increasing interest to all scientists, especially those monitoring small variations in the earth’s surface, such as coastline morpholog...
Coastal erosion is a major coastal hazard in Greece. This work aimed to assess the perceptions of citizens about erosion. We developed questionnaire containing 25 questions that was distributed online and filled out by 1636 respondents. A surprising find 33% respondents were not aware phenomenon On other hand, among those who are erosion, there basic understanding factors promoting its impacts....
Coastal areas in England and Wales are at greater risk of flooding and erosion than their landward equivalents. To address these hazards, over the last 20 years, a process to develop long-term Shoreline Management Plans (SMPs) has been developed (Leafe et al., 1998; Cooper et al., 2002; DEFRA, 2006). The spatial boundary of SMPs is defined by coastal cell and sub-cell boundaries (of order 10 2 ...
The risk of climate-change induced sea-level rise damage to human and economic development in coastal areas of The Gambia is mounting. The combined effect of sea-level rise and changes in upstream river discharge, erosion of coastal embankmentsand changes to natural sediment dynamics, pose a serious threat to the natural resources base and livelihood opportunities of coastal communities(UNDP, 2...
The objective of this paper is to provide a general overview of the influence of wildland fires on the erosional processes common to the forested landscapes of the western United States. Wildfire can accelerate erosion rates because vegetation is an important factor controlling erosion. There can be great local and regional differences, however, in the relative importance of different erosional...
Extreme weather, sea-level rise and degraded coastal ecosystems are placing people and property at greater risk of damage from coastal hazards1–5. The likelihood and magnitude of losses may be reduced by intact reefs and coastal vegetation1, especially when those habitats fringe vulnerable communities and infrastructure. Using five sea-level-rise scenarios, we calculate a hazard index for every...
