Tapping Alternative Sources to Quench Growing Thirst

Iran is to implement groundwater detection in karst regions for the first time as a national scheme organized by Geological Survey and Mineral Explorations of Iran (GSI).
"The project primarily aims to detect and harness the ground water that flows out of the country's borders or empties into seas so as to supply freshwater for drought-stricken areas at the next stage, as an alternative to inter-basin water transfer," Masoud Morsali, an advisor at GSI, said. 
Unlike the earlier similar projects, which were carried out via magnetometry and radiometry, the current scheme is being implemented utilizing the latest electromagnetic techniques with the help of airborne geophysics, IRNA reported. 
Compared to former approaches, the new technique is faster and capable of monitoring deeper layers of the earth (up to 400 meters), Morsali noted.
