Étang De Vaccarès
Étang de Vaccarès is a lake, or, more accurately, a salt water lagoon (), in the wetlands of the Camargue in the delta of the River Rhône in southern France. Description The lake has an area of 65 km2, and the depth is less than two meters. It is the northernmost, and also the largest of the lakes of the Camargue, and constitutes the principal element in the water control system of the Rhône delta, which depends upon a strict management of water resources, through pumping, irrigation and draining stations making a complex network of channels throughout the river delta. The lake is also an important place for rest and food for migratory birds, and it also has a population of the greater flamingo. Because of its importance for wild birds, the Étang de Vaccarès with its surrounding wetlands has been protected as a nature reserve since 1927, and in 1972 it was incorporated into the Parc Régional de Camargue. Pollution Even though the lake is «protected», it is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camargue Étang De Vaccarès
The Camargue (, also , , ; ) is a coastal region in southern France located south of the city of Arles, between the Mediterranean Sea and the two arms of the Rhône river delta. The eastern arm is called the Grand Rhône; the western is the ''Petit Rhône''. Administratively, it lies within the Departments of France, department of Bouches-du-Rhône (‘Mouths of the Rhône’); it spans portions of the Communes of France, communes of Arles, Saintes-Maries-de-la-Mer and Port-Saint-Louis-du-Rhône. A further expanse of marshy plain, known as the "Petite Camargue" (Little Camargue), just to the west of the "Petit Rhône", lies within the department of Gard. The Camargue was designated a Ramsar site as a "Wetland of International Importance" on 1 December 1986. The Petite Camargue received this designation on 8 January 1996.

Lagoon
A lagoon is a shallow body of water separated from a larger body of water by a narrow landform, such as reefs, barrier islands, barrier peninsulas, or isthmuses. Lagoons are commonly divided into ''coastal lagoons'' (or ''barrier lagoons'') and ''atoll lagoons''. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as Estuary, estuaries. Lagoons are common coastal features around many parts of the world. Definition and terminology Lagoons are shallow, often elongated bodies of water separated from a larger body of water by a shallow or exposed shoal, reef, coral reef, or similar feature. Some authorities include fresh water bodies in the definition of "lagoon", while others explicitly restrict "lagoon" to bodies of water with some degree of salinity. The distinction between "lagoon" and "estuary" also varies between authorities. Richard A. Davis J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rhône
The Rhône ( , ; Occitan language, Occitan: ''Ròse''; Franco-Provençal, Arpitan: ''Rôno'') is a major river in France and Switzerland, rising in the Alps and flowing west and south through Lake Geneva and Southeastern France before discharging into the Mediterranean Sea (Gulf of Lion). At Arles, near its mouth, the river divides into the Great Rhône () and the Little Rhône (). The resulting River delta, delta forms the Camargue region. The river's source is the Rhône Glacier, at the east edge of the Cantons of Switzerland, Swiss canton of Valais. The glacier is part of the Saint-Gotthard Massif, which gives rise to three other major rivers: the Reuss (river), Reuss, Rhine and Ticino (river), Ticino. The Rhône is, with the Po (river), Po and the Nile, one of the three Mediterranean rivers with the largest Discharge (hydrology), water discharge. Etymology The name ''Rhône'' continues the Latin name (Ancient Greek, Greek ) in Greco-Roman geography. The Gaulish name of t ...

Migratory Birds
Bird migration is a seasonal movement of birds between breeding and wintering grounds that occurs twice a year. It is typically from north to south or from south to north. Migration is inherently risky, due to predation and mortality. The Arctic tern holds the long-distance migration record for birds, travelling between Arctic breeding grounds and the Antarctic each year. Some species of tubenoses, such as albatrosses, circle the Earth, flying over the southern oceans, while others such as Manx shearwaters migrate between their northern breeding grounds and the southern ocean. Shorter migrations are common, while longer ones are not. The shorter migrations include altitudinal migrations on mountains, including the Andes and Himalayas. The timing of migration seems to be controlled primarily by changes in day length. Migrating birds navigate using celestial cues from the Sun and stars, the Earth's magnetic field, and mental maps.

Greater Flamingo
The greater flamingo (''Phoenicopterus roseus'') is the most widespread and largest species of the flamingo family. Common in the Old World, they are found in Northern (coastal) and Sub-Saharan Africa, the Indian Subcontinent (south of the Himalayas), the Middle East, the Levant, the Persian Gulf, the Gulf of Aden, the Red Sea, and the Mediterranean countries of Southern Europe. Taxonomy The greater flamingo was described by Peter Simon Pallas in 1811. It was previously thought to be the same species as the American flamingo (''Phoenicopterus ruber''), but because of coloring differences of its head, neck, body, and bill, the two flamingos are now most commonly considered separate species. The greater flamingo has no subspecies and is therefore monotypic. Description The greater flamingo is the largest living species of flamingo, averaging tall and weighing . The largest male flamingos have been recorded to be up to tall and to weigh . Most of the plumage is pinkish-whit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollution
Pollution is the introduction of contaminants into the natural environment that cause harm. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Although environmental pollution can be caused by natural events, the word pollution generally implies that the contaminants Human impact on the environment, have a human source, such as manufacturing, Extractivism, extractive industries, poor waste management, transportation or Agricultural pollution, agriculture. Pollution is often classed as point source pollution, point source (coming from a highly concentrated specific site, such as a factory, Environmental effects of mining, mine, construction site), or nonpoint source pollution (coming from a widespread distributed sources, such as microplastics or agricultural runoff).

Landforms Of Bouches-du-Rhône
A landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great oceanic basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type. Gross physical features or landforms include intuitive elements such as berms, cliffs, hills, mounds, peninsulas, ridges, rivers, valleys, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodi ...
