摘要
A method of monitoring an advance of seawater toward a fresh water aquifer, an observation well penetrating said fresh water aquifer, said observation well having a casing, comprising the steps of:locating a resistivity array within or around said casing of said observation well, an aquifer being located around said resistivity array;using said resistivity array, measuring a resistivity value or a conductivity value of a water based substance in said aquifer around said resistivity array, the values of said resistivity or conductivity being representative of a presence or an absence of either seawater or fresh water in said water based substance in said aquifer.
