Título:
Water balance and observed flows in the Anllóns river basin (NW Spain)
Resumo:
During three years (2001, 2002, 2003) several streamflow measurements surveys were carried out in the Anllóns river basin, as well as an integral study of its hydrological characteristics that has provided an important knowledge of its hydrological behaviour. Has been obtained the annual hydrographs for each hydrological year and were carried out its separation into their basic components: surface water and baseflow. The baseflow component of streamflow was obtained by means of HYSEP computer program, developed by USGS). the mean value of the groundwater recharge for the study period was 72% of the total streamflow of the river. At the same time, with the registered precipitation and the value of the evapotranspiration calculated with the data of the nearest meteorological stations, has been calculated the soil water balance using the Thornthwaite y Matter methodology for each observed year, and the results obtained has been compared with the observed data.
