Caracterización hidroquímica de los arroyos que vierten a la Ría de Huelva

The estuary known as Ría of Huelva receives the flow of two rivers intensely affected by acid mine drainage (AMD), the Odiel and Tinto rivers. The aim of this work is to evaluate the quality and the seasonal variations of the surface waters, no affected by AMD, which drain into the Ría of Huelva. We...

Description
Summary:The estuary known as Ría of Huelva receives the flow of two rivers intensely affected by acid mine drainage (AMD), the Odiel and Tinto rivers. The aim of this work is to evaluate the quality and the seasonal variations of the surface waters, no affected by AMD, which drain into the Ría of Huelva. We carried out a sampling campaign during one year in seven streams which drain an agricultural area with some small villages. The hidrochemistry of these streams depends on the lithology of the catchment and anthropogenic inputs. The seasonal dilution of organic discharges and the leaching of nitrates from agricultural activities are the main parameters affecting the quality of the water of these streams
