Monitoring of Seawater Intrusion in Coastal Aquifers: Basics and Local Concerns

摘要

Monitoring of seawater intrusion is essential to determine and predict groundwater deterioration, and assess other managerial activities in coastal aquifers. Monitoring involves designing strategy and methodology of field surveys for choosing the most effective means towards obtaining the most reliable possible data. The monitoring of seawater intrusion may consist of direct and indirect methods. Direct methods include measurement of groundwater salinity profiles and groundwater sampling of observation and active wells. Such sampling can involve single-chamber apparatus or multi-layer samplers. Indirect methods can use geoelectromagnetics and more specifically the time domain electromagnetic method (TDEM).
