Contribución de datos Iisimétricos a la evaluación de la Recarga al Acuifero Almonte-Marismas

Abstract

This work presents Almonte-Marismas aquifer recharge data obtained from a pair of lysimeters at a farming site located South El Rocío. Many Doñana National Park ecosystems depend on aquifer supplies. Results of actual évapotranspiration show outstanding differences the two years of control with similar precipitations. Is noted that presence of a piezometric level close to surface increase recharge, although on the other hand losses for évapotranspiration are favoured. The results are compared with those obtained from a daily soil water balance using the potential évapotranspiration calculated from Thornthwaite,
