Abstract
In recent decades, coastal areas have experienced a progressive increase in erosion and flooding processes as a consequence of the combined effect of natural factors and strong human pressures. These processes are particularly evident on low-lying areas and are expected to be exacerbated by the ongoing climate change, which will impact the littorals both in the short term, by affecting the duration and frequency of storms, and in the long term, by inducing variation in the sea-level position. In this context, this Special Issue is devoted to collecting geomorphological studies on coastal dynamic and evolution by means of multidisciplinary research methodologies and investigations, which represent a very useful set of information for supporting the integrated management of coastal zone. The volume includes 14 papers addressing three main topics (i) shoreline characterization, dynamic and evaluation; (ii) coastal hazard evaluation and impact assessment of marine events; and (iii) relevance of sediment collection and analysis for beach nourishment. Case studies from Russia, Italy, California (USA), Morocco, Spain, Indonesia, Ireland and Colombia are shown in the Special Issue, giving to the reader a wide overview of coastal settings and methodological approaches.
Highlights
The present-day coastal landscape is essentially the result of the interaction among different factors, including the geological frame as well as continental and marine factors
Eight papers belong to this category and provide information concerning the characterization and evolution at different spatial and temporal scales of a great variety of coastal environments, including mangrove swamps, and sandy and rocky coasts and dune ridges in coastal sectors located in Russia, Italy, California (USA), Morocco and Spain
The high variability and dynamics of coastal morphologies and landforms require the application of tailored approaches for the assessment of local changes in the short, medium, and long term
Summary
The present-day coastal landscape is essentially the result of the interaction among different factors, including the geological frame as well as continental and marine factors. Further targets under SDG 14 as well as targets under other goals, though not explicitly referred to coastal areas, are implicitly relevant for coastal areas and for the protection, conservation and management of coastal ecosystems and resources [9] In this context, a crucial role is played by sensitivity/vulnerability and risk analysis studies, which allow for the evaluation of coastal proneness to hazardous processes such as erosion, flooding, and submersion, as well as potential coastal resilience capacity at global [11,12,13], regional [14,15,16,17,18] and local [19,20,21,22,23,24] levels.
