Article
Full-text available
The geomorphology of the Rufiji River delta was investigated with emphasis on the influence of the delta’s context, including the river basin, and remote-sensed delta-plain channel connectivity and shoreline morphological, sedimentary and hydrodynamic variations. The Rufiji is influenced by its East African Rift Valley tectonic context, high inter-...
Article
Full-text available
The Amazon River delta may be currently characterized biophysically as a relatively preserved delta compared to the rampant vulnerability of many of the world’s large deltas. This status of relative preservation is reflected in a number of criteria: The still largely free-flowing nature of many of the rivers and the main stem of the Amazon that fee...
Article
Full-text available
Areal changes over delta surfaces determined by land and water ratios are a promising tool for identifying spatial and temporal changes in deltas that may reveal subsidence and shoreline erosion. Such changes can also provide the basis for more detailed studies on variations in land-cover and vegetation. Changes in land and water areas over a 35-ye...
Article
A morpho-sedimentary analysis of the Ayeyarwady delta shoreline was conducted based on a field mission in Myanmar in November 2016 and interpretation of satellite images spanning the period 1974-2019. These analyses were complemented by data on land-to-water conversion and vice versa within a 2 km-wide coastal fringe, and on MERIS-derived seasonal...
Article
The question of the rampant erosion of the shorelines rimming the Mekong River delta has assumed increasing importance over the last few years. Among issues pertinent to this question is how it is related to mangroves. Using high-resolution satellite images, we compared the width of the mangrove belt fringing the shoreline in 2012 to shoreline chan...
Preprint
The inception, growth, and decline of numerous large and small river deltas on Earth have been strongly influenced by human population dynamics and interventions on catchments, notably deforestation and reforestation. Over the last half century, the effects of catchment conditions in determining fluvial sediment supply have been exacerbated or mode...

The Bight of Benin in the Gulf of Guinea, West Africa, forms an embayment between the Volta River delta in the west (Ghana) and the Niger River delta (Nigeria) in the east. The bight coast comprises sandy beaches backed by Holocene beach-ridge barriers. Incident swell waves, beachface gradient and the unidirectional longshore sand transport from we...
Article
The Ayeyarwady River delta (Myanmar) is a tide-dominated, meso-macrotidal delta characterized by multiple distributary mouths and affected by low to moderate-energy southwest monsoon waves. The delta lies in the pathway of tropical cyclones, of which the most devastating was Nargis (2-4 May, 2008), which resulted in severe socio-economic damage. Th...
Article
The Mediterranean basin (including the Black Sea) is characterized by a plethora of deltas that have developed in a wave-influenced setting. Many of these deltas are sourced in sediments by river catchments that have been variably dammed. The vulnerability status of a selection of ten deltas subject to different levels of reduction in fluvial sedim...
Article
River delta shorelines composed of sand may be characterized by complex spatial and temporal patterns of erosion and accretion even when sand supply is readily available. This is especially the case for deltas with multiple mouths subject to significant wave and tide influence. High-resolution topographical and wave and current measurements were co...
Poster
Full-text available
The influence of physical processes on river deltas has long been identified, mainly on the basis of delta morphology. A cuspate delta is considered as wave-dominated, a delta with finger-like extensions is characterized as river-dominated, and a delta with estuarine re-entrants is considered tide-dominated (Galloway, 1975). The need for a more qua...

Full-text available
River delta vulnerability is mostly due to environmental modifications resulting from climate change and human activities. Here, we address the problem of delta erosion based on the analysis of 10 Mediterranean and Black Sea deltas. Using satellite images (Landsat, Spot 6) and aerial photographs, we determined for each delta, the change in delta pr...
Article
The Mekong River delta is the world’s third largest delta, consequence of a favourable morphosedimentary setting, high sediment supply and rapid growth during the Holocene. Analysis of Landsat satellite images from 1973 to 2014 shows that nearly 70 % of the 160 km - long South China Sea shoreline of the delta has strongly eroded. This trend represe...
Presentation
The Holocene Mekong River delta prograded rapidly in a relatively sheltered bight in the South China Sea under the influence of high fluvial sediment supply 5300 to 3500 years ago, developing from an estuary into a delta. This bight infill led to increasing exposure of the prograding shoreline of the delta to ocean waves, resulting in a greater wav...
Presentation
Full-text available
River deltas are considered as increasingly vulnerable to environmental modifications resulting from climate change and human activities. Delta vulnerability is associated with a number of drivers, chief among which are depleted sediment supply, changes in water discharge, and pumping of underground fluids. These activities lead to accelerated subs...

The Mekong River delta prograded rapidly in a relatively sheltered bight in the South China Sea under the influence of high fluvial sediment supply 5300 to 3500 years ago, developing from an estuary into a delta. This >200 km seaward growth resulted in increasing exposure of the delta to ocean waves that led to a more wave-influenced mode of progra...
Presentation
River delta shorelines may be characterised by complex patterns of sediment transport and sequestering at various timescales. These aspects are examined with reference to the mouths of the Mekong River delta, the world’s third largest delta, backbone of the Vietnamese economy and home to nearly 20 million people. Very high-resolution SPOT 5 satelli...
Article
Full-text available
As international concern for the survival of deltas grows, the Mekong River delta, the world's third largest delta, densely populated, considered as Southeast Asia's most important food basket, and rich in biodiversity at the world scale, is also increasingly affected by human activities and exposed to subsidence and coastal erosion. Several dams h...
Presentation
The complexity of coastal river deltas lies in part in aspects of sediment supply and redistribution, trapping and readjustment. The sediment supply and involved processes are governed by river-marine forcing, weather and climate, increasingly affected by humans, all within a frame of interactivity and morphodynamic equilibrium/disequilibrium that...
