Multi-Decadal Deltaic Land-Surface Changes: Gauging the Vulnerability of a Selection of Mediterranean and Black Sea River Deltas

Areal changes over delta surfaces determined by land and water ratios are a promising tool for identifying spatial temporal in deltas that may reveal subsidence shoreline erosion. Such can also provide the basis more detailed studies on variations land-cover vegetation. Changes areas 35-year period (1984–2019) were selection of ten river Mediterranean (Nile, Rhône, Po, Ebro, Moulouya, Ceyhan-Seyhan, Medjerdja, Ombrone, Arno) Black Sea (Danube), with particular focus aspects With exception Arno, to lesser extent where notable dominate coastal zone tantamount net erosion, pattern is largely dominated delta-plain characterized increasing water. The reflects mix land-use changes, such as ecological restoration wetlands, but these deltas, all which have been exposed declining fluvial sediment supply due human influence. use data land-water needs be complemented devoted each order clearly disentangle related land-use, vegetation, subsidence.
