The Point Eidothermometric Method in the Study of Coastal Aquifers

The eidothermometricm ethod consists of the visualization (from the Greek word "eidos"= image)of the time evolution of thermometry in a waters column, by reconstruction of the various isotherms.The image thus obtained,were basal thermometry is subject to influences of different kinds, will show such disturbances through thermometric anomalies. The maÍn advantage offered by this method is to obtain, even at those wells with no previous information, reliable and useful data on the aquifer permeability,the occurrence of preferential discharge levels or impervious levels,and water circulation dynamics. The use of said method, moreover proved to be fully satisfactory both when used in relation to short-term thermal influences caused by tides and when used in relation to long-term influences caused by sea conditions. Similar to eidothermometry, eidosalinometry also provided useful information not usually obtained by normal saline logs.
