A ria is a landform, often referred to as a drowned river valley. Rias are almost always estuaries. An estuary is a semi-enclosed Coastal body of Water with one or more Rivers or Streams flowing into it and with a free connection to the open Rias form where sea levels rise relative to the land either as a result of eustatic sea level change (where the global sea levels rise), or isostatic sea level change (where the land sinks). When this happens valleys which were previously at sea level become submerged. In Geology, a valley (also called a vale, dale, glen or strath and near or in Appalachia, a draw) is The result is often a very large estuary at the mouth of a relatively insignificant river (or else sediments would quickly fill the ria). The Kingsbridge Estuary is an extreme example of a ria forming an estuary disproportionate to the size of its river; no significant river flows into it at all, only a number of small streams. The Kingsbridge Estuary (also known as the 'Salcombe Estuary' is located in the South Hams area of Devon, England, running from Kingsbridge

The Rias region is one of high rainfall and moderate temperatures—between 0°C and 30°C. The variety of scenery and the beaches along these calm, relatively warm waters, attract tourists to such resorts as Sanxenxo and A Toxa.
