Layer: Waterlevel Change 2005 to 2017 (ID: 3)

Name: Waterlevel Change 2005 to 2017

Display Field: Classes

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Changes in the groundwater level of Abu Dhabi Emirate are closely linked to agricultural activity. Areas with a strongly declining water table coincide with the areas of highest groundwater abstraction for agricultural irrigation. The areas around Remah and Al Wagan illustrate this best. In the course of 25 years, the water level in groundwater monitoring wells has dropped by more than 50 m. The map shows the groundwater level change between 2005 and 2017. While yellow and red areas face a continued decline of groundwater levels, in blue areas a relative rise is observed. This relative rise is mainly attributed to a small reduction in agricultural activity and shut-down of well fields. Though between 2005 and 2017 the groundwater level slightly increased in these areas, an absolute drawdown prevails compared with the natural state. True rising of the water table takes place only in the vicinity of Al Ain, where losses from the water network and excessive landscape irrigation leads to rising water levels above the natural state.
