Evolución del contacto agua dulce-agua salada en un acuífero kárstico costero: acuífero de Aguadulce (Almería)

Abstract

Karstic aquifers display a large number of singularities regarding the underground flow organisation and the vertical distribution of the water heads, due to the unequal behaviour of the karstic drains and channels compared to the matrix. In the coastal aquifers, the existence of a saltwater and a mixing zone, whose dynamics may turn very complicated, must be added to the usual complexity. The monitoring of the piezometric level and electrical conductivity evolution in a borehole in the Campo de Dalias aquifer allow the exposition of a series of considerations about the evolution of the measured parameters and the factors that determine this evolution
