From: Investigating meteorological/groundwater droughts by copula to study anthropogenic impacts
(a) Location map of the study area; (b) spatial distribution of Met drought return period within the Lake Urmia basin; and (c) spatial distribution of GW drought return period within the aquifers around the lake. Note 1:Â The contours for each aquifer varies but not much and more often are lower (more severe) than those of Met droughts. Note: 2:Â The figure is produced by the authors using QGIS 3.01 v 2018.
