Integrated geophysical and hydrochemical investigations for seawater intrusion: a case study in southwestern Saudi Arabia

The objective of the present study was to assess the deterioration in groundwater quality due to saline water intrusion in the Ad-Darb region of southwestern Saudi Arabia. An integrated approach using geochemical and geophysical methods was applied to assess the extent of saline water intrusion. Geochemical methods involved the determination of main groundwater facies present in the region using Piper and extended Durov plots. The geophysical...
