Abstract The overarching morphosedimentary control on the coast of South America between Amazon and Orinoco rivers is massive muddy discharge (from c. 754×10 6 to 1000×10 t a −1 ). This mud supply by world’s largest river reflects sediment sourcing from Andes, weathering in tropical–equatorial climate extremely high water ( ca 173 000 m 3 s forms an estuarine mega-turbidity maximum shelf that feeds growth subaqueous delta. About 15–20% this coastal banks migrate towards mouth Orinoco, which...
Abstract Aim The goal of the study was to quantify changes in extent mangroves since mid‐twentieth century and test hypothesis that these are driven by ocean waves. Location pristine 300‐km‐long coast French Guiana, South America. Methods We produced time series mangrove maps using archival remote sensing images. retrieved significant wave heights ( H S ), mean periods T M ) directions (θ from European Centre for Medium‐Range Weather Forecasts reanalysis products. used complex empirical...
Abstract Probably the largest regular shoreline fluctuations on Earth occur along 1500 km‐long wave‐exposed Guianas coast of South America between mouths Amazon and Orinoco Rivers, world's longest muddy coast. The is influenced by a succession mud banks migrating northwestward from Amazon. Migrating dissipate waves, partially weld onshore, lead to coastal progradation, aided large‐scale colonization mangroves, whereas mangrove‐colonized areas (inter‐bank areas) are exposed strong wave action...
The 350-km long coast of Suriname, South America, is part a unique system in the world characterized by large-scale mud supply from Amazon and exposed to Atlantic waves. Large banks migrate alongshore Orinoco delta, separated 'inter-bank' zones. Banks dissipate waves, create new land, aided mangroves, whereas waves inter-bank areas cause shoreline erosion, mitigated where sandy/shelly cheniers develop. Cheniers are rare due sand/shell burial mud. They assure coastal protection, recreational...
The muddy Guyanas coastline in South America experiences significant short-term change involving alternations of accretion and erosion as a result the influence mud from Amazon River. In French Guiana, dynamic changes due to banks permanently migrating alongshore have considerable impact on both coastal ecology economic activities. As result, monitoring these constitutes an important management issue. this article, focus is placed development method for bank migration rates since 1986...
The estuarine turbidity maximum (ETM) zone occurs in river estuaries due to the effects of tidal dynamics, density-driven residual circulation and deposition/erosion fine sediments. Even though tropical contribute proportionally more sediment supply coastal areas, ETM them has been hardly studied. In this study, surface suspended particulate matter (SPM) determined from OLI (Operational Land Imager)-Landsat 8images was used gain a better understanding spatio-temporal dynamics Maroni estuary...
Abstract Montjoly is a headland‐bound embayed sandy beach in Cayenne, French Guiana, that shows long‐term plan shape equilibrium spite of periodic changes accretion and erosion alternately affect either end the beach. These are caused by mud banks move alongshore from Amazon. The mechanisms involved response to passage one these were monitored between 1997 2000 airborne video imagery field work. longshore drift northwest, driven incident easterly northeasterly swell usually affecting this...
The coast of French Guiana is characterised by the northwestward migration large mud banks alongshore and high concentrations suspended particulate matter (SPM) resulting from strong influence Amazon River outflow. Surface OLI SPM concentration, linked to footprint subtidal part due resuspension processes, was used develop a method estimate location this footprint. A comparison results with those obtained locating limit wave damping, which characterises muddy coasts, revealed good...
