Abstract
In a previous paper, the atmospheric chloride mass balance (CMB) method for spatial average diffuse aquifer recharge by rainfall ((R) over bar) in large and varied territories was evaluated. Continental Spain was chosen to show the reliability of this application. Two main sources of uncertainty (measured by the coefficient of variation, CV) affecting (R) over bar, induced by the inherent natural variability of the variables (CVR) and from mapping (CVRK), were separated. While CVRK may be decrea...
