Abstract: | Water quality levels and loads of nutrients transported by the Agüera stream (northern Spain) were studied for a year to assess
the self-purification capacity of this system. The main villages produce an increase of nutrient concentrations and a degradation
of water quality. Nevertheless, the high retention capacity, especially for phosphate, allows the stream to recover its previous
levels of quality after a short reach. The retention of nutrients depends on a complex combination of the flow level, hydrologic
stability and the development of periphytic communities. |
