Rivers Of Loire-Atlantique
A river is a natural stream of fresh water that flows on land or inside caves towards another body of water at a lower elevation, such as an ocean, lake, or another river. A river may run dry before reaching the end of its course if it runs out of water, or only flow during certain seasons. Rivers are regulated by the water cycle, the processes by which water moves around the Earth. Water first enters rivers through precipitation, whether from rainfall, the runoff of water down a slope, the melting of glaciers or snow, or seepage from aquifers beneath the surface of the Earth. Rivers flow in channeled watercourses and merge in confluences to form drainage basins, or catchments, areas where surface water eventually flows to a common outlet. Rivers have a great effect on the landscape around them. They may regularly overflow their banks and flood the surrounding area, spreading nutrients to the surrounding area. Sediment or alluvium carried by rivers shapes the landscape ar ...

Pays De Retz
The Pays de Retz (; ; ) is a historical subregion of France that currently forms part of the Loire-Atlantique department, but once formed part of the Duchy of Brittany. The area lies between the southern shore of the Loire estuary and the '' Marais breton'' (Breton marshlands), bordered to the west by the ''Baie de Bourgneuf'' (Bourgneuf Bay) and on the east by the ''Lac de Grand-Lieu'' (Grand-Lieu Lake) and a network of small rivers. Its main towns are Rezé (which was its capital and the see of a Catholic Diocese of Rezé from 510 to 851), Pornic, Paimbœuf and Machecoul (another historical capital city). History In the early 9th century the area formed part of Frankish territory, but was coveted by the Breton ruler Nominoe. Nominoe and his son Erispoe won a series of victories over the Franks between 843 and 851, resulting in the Treaty of Angers (851) between Charles the Bald and Erispoe, which gave "''Ratense''" or ''Pays de Retz'' to Brittany. In subsequent centuries ...
