This study proposed an evaluation model for the attenuation capacity of vadose zone to supplement the limitations of theexisting index method models for assessing groundwater vulnerability. The evaluation equation for quantifying theattenuation capacity was developed from the combined linear regression and weighted scaling methods based on the labscaleexperiments using various vadose zone soils having different physical and biogeochemical properties. The proposedsemi-quantifying model is expected to effectively assess the attenuation capacity of vadose zone by identifying the maininfluencing factors as input parameters together with proper weights derived from the coefficients of the regression results. The subsequent scoring and grading system has great versatility while securing the objectivity by effectively incorporatingthe experimental results.
