Coastal Risk: Shores and Deltas in Peril

The interaction between land and sea is controlled by a number of processes that are in general driven by the equilibrium between environmental forcing components (e.g. hydrodynamic - waves, currents, surges), atmospheric (e.g. winds) and terrestrial (e.g. catchment land cover) and sediment dynamics. In the context of the Anthropocene epoch, the equilibrium in many coastal regions is now often altered by the influence of human activities. Successive human activities globally influence (indirectly) these forcing components, helping magnify the negative impact of extreme meteorological events and sea level rise. Directly, human activity can also influence a number of processes at a local scale within and between the catchment, the sea and the coast. For example, misplaced engineered infrastructure inside these naturally dynamic environments can accentuate disequilibrium, destabilizing shores and deltas. Development in catchments can promote rapid runoff, inducing sometimes-dramatic effects on downstream urbanized areas, the socio-economy as well as on coastal resources and ecosystems. This Research Topic aims to assemble research and review papers that focus on the dynamics of shores and deltas in peril under present conditions as well as in the future context of sea-level rise, climate change and adaptation strategies under various scenarios.
