In Iran, Depleted Aquifers Cause Land to Sink
Researchers have found that the growing use of groundwater in Iran has greatly depleted the nation's water supply and also has deformed land surfaces.
The international scientists found that decades of unrestrained groundwater extraction are linked to land surface deformation on local and regional scales. They made these findings using water level data and satellite radar observations.
"Comparing ground deformation in Iran with other basins around the world revealed that Iran currently hosts some of the fastest sinking valleys and plain aquifers in the world," the scientists said.
The scientists involved in this research included, Jan Anderssohn, Thomas Walter and Jochen Zschau from the Geo Research Center in Potsdam, Germany; Eric Fieldking of the Jet Propulsion Laboratory in Pasadena,CA; Mohammad Ali Sharifi of the University of Tehran; and Andreas Schenk of the Geodetic Institute at Germany's Karlsruhe University, as reported by United Press International.
