Description :
The study of groundwater tables variations due to ocean-tide effects in a coastal aquifer may yield its hydrodynamical characteristics. Such a study has been attempted about a zone of the limestone of the Miocene of Algarve (Portugal). Two computation methods can be utilized, depending on the form of the free-water table evolution: (1) a Carson-Laplace transform, or (2) adjustment of a sinusoidal variation law to the fluctuations. Their application has permitted to characterize the aquifer's general hydrodynamical behaviour. The model that gives the most satisfying reconstitutions of the observations points out a seepage situation which fits quite well to the known geological conditions of the aquifer. (The AA).
