Ria
A ria (; , feminine noun derived from ''río'', river) is a coastal inlet formed by the partial submergence of an unglaciated river valley. It is a drowned river valley that remains open to the sea. Definitions Typically rias have a dendritic, treelike outline although they can be straight and without significant branches. This pattern is inherited from the dendritic drainage pattern of the flooded river valley. The drowning of river valleys along a stretch of coast and formation of rias results in an extremely irregular and indented coastline. Often, there are naturally occurring islands, which are summits of partly submerged, pre-existing hill peaks. (Islands may also be artificial, such as those constructed for the Chesapeake Bay Bridge-Tunnel.) A ria coast is a coastline having several parallel rias separated by prominent ridges, extending a distance inland.Goudie, A. (2004) ''Encyclopedia of Geomorphology.'' Routledge.

Rías Baixas
The Rías Baixas ( Galician for "Lower Rias") are a series of four estuarine inlets located on the southwestern coast of Galicia, Spain. They are the Ría de Muros e Noia, the Ría de Arousa, the Ría de Pontevedra, and the Ría de Vigo.Mendez & Vilas (2004), p. 196. The northernmost Rías Baixas begin below Cape Finisterre while the southernmost rias border the Portuguese coast, taking up the southern part of the Province of Coruña and the entire Province of Pontevedra. Its capital is the city of Pontevedra. Due to unique conditions, the Rías Baixas are rich in marine life which helps the fishing and aquaculture industry of the area. Beaches, marinas, distinctive towns, and plenty of water activities also attract tourists, providing another source of income. Geology Though individually distinct, each of the Rías Baixas share some common characteristics. They begin along the coastline of the Atlantic Ocean and jut inland, eventually meeting up with a river. Each ria ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ria Formosa
The Ria Formosa lagoon, located in the Algarve, in southern Portugal, is a system of barrier islands that connects to the sea through six inlets. Five of these inlets are natural and have mobility characteristics. The sixth is an artificial inlet that was opened with the purpose of allowing easier access to the port of Faro. In 2010, the lagoon was recognised as one of the country’s seven natural wonders. Following a public vote in which 656,356 voted, the Ria Formosa was announced the winner of the Marine Area category of the ‘7 Maravilhas Naturais de Portugal’. Presently the main inlet of the system is the Faro-Olhão inlet, which is an artificial construction. The process started in 1927 but it was only in 1952 that the engineering works were completed and it assumed the present configuration. Part of the system is a 170 km² protected natural area, but Ria Formosa also plays an important role in the region's economy. Beyond the tourist use the system also sup ...

Estuary
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as ba ...
