Description
Application
PI
Protective cover (P), infiltration conditions
(I)
D
i = PTS*I. A lower D
i value indicates worse mitigation
performance and more vulnerability of the aquifer to
contamination. The model is more applicable to
vulnerability assessment of resource protection
Karst water
AVI
Vertical hydraulic conductivity, thickness of
layers above the water surface
The model measures the aquifer sensitivity by the
hydraulic resistance of layers in the direction perpendicular
to water
flow and quantifies the average time of transport
from land surface to groundwater for pollutants
Simple and fast
SIGA
Soil media (S), vadose zone media
(I), ground surface slope (G), aquifer media
(A)
A higher score indicates worse mitigation performance, and
vice versa
It is complex with
difficulty in obtaining
parameter values, but the
score is relatively accurate
SINTACS
Depth to water table (S), net recharge (I),
vadose zone dilution capacity
(N), soil media (T), aquifer media
(A), hydraulic conductivity (C), slope (S)
Same as DRASTIC model
Medium and large-scale
