| Coverage |
Water levels were monitored in 69 wells in the Kabul Basin, Afghanistan, starting in July 2004 and continuing through March 2007. The monitoring network is composed of existing water-supply wells; therefore, both static and dynamic water levels were recorded. Very little information is available about the construction or completion of the wells, and there are no geologic logs for the wells being monitored. The majority of the wells are completed in Tertiary or Quaternary sediments. Water levels were measured periodically, generally monthly, by engineers from the Afghanistan Geological Survey using 100-meter electric tapes. Well depths in the study area ranged from 4.9 to 160 meters. Water levels below land surface ranged from less than 1.5 to 68 meters, while static water levels ranged from 1.5 to 40 meters. Seasonal water-level fluctuations from September 2005 through May 2006 ranged from less than 1 to 8 meters. Water level trends during the study period showed both increases and decreases. Drawdowns due to pumping ranged from 5 to 25 meters. |
