However, specific graphical methods can be applied by the geologist-geophysicist in order to interpret manually geoelectric sounding data which have been obtained from a zone of saline water invasions. A brief description of these methods is given including the relevant references for directed reading.The practical application of one particular interpretation method is illustrated in a case history from Nacaome, Honduras. It also shows the general versatility of geoelectric surveys for obtaining in a short time and at a low cost qualitative information of exploitable groundwater resources in coastal areas.
