Abstract As international concern for the survival of deltas grows, Mekong River delta, world’s third largest densely populated, considered as Southeast Asia’s most important food basket and rich in biodiversity at world scale, is also increasingly affected by human activities exposed to subsidence coastal erosion. Several dams have been constructed upstream delta many more are now planned. We quantify from high-resolution SPOT 5 satellite images large-scale shoreline erosion land loss...
The Mediterranean basin (including the Black Sea) is characterized by a plethora of deltas that have developed in wave-influenced setting. Many these are sourced sediments river catchments been variably dammed. vulnerability status selection ten subject to different levels reduction fluvial sediment supply following damming was analysed quantifying changes delta protrusion area and angle over last 30 years. rationale for choosing two metrics, which do not require tricky calculations...
The Ayeyarwady River delta (Myanmar) is exposed to tropical cyclones, of which the most devastating has been cyclone Nargis (2–4 May 2008). We analysed waves, flooded area, nearshore suspended sediments, and shoreline change from satellite images. Suspended sediment concentrations up 40% above average during may reflect fluvial mud supply following heavy rainfall wave reworking shoreface mud. Massive recession high-water line resulted backshore flooding by surge. showed a mean retreat 47 m...
The Mekong River delta is the world's third largest delta, consequence of a favourable morphosedimentary setting, high sediment supply and rapid growth during Holocene. Analysis Landsat satellite images from 1973 to 2014 shows that nearly 70 % 160 km - long South China Sea shoreline has strongly eroded. This trend represents reversal massive, long-term Holocene progradation characterized this part delta. Erosion land loss along coast are not related lobe switching, but more likely decreasing...
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...
