• The soil attributes and the corresponding
weights used for calculating the vulnerability index for pollution by runoff
(surface waters) are:
•Dominant parent
material. For “Detrital
formations”, “Crystalline rocks and migmatites” and “Volcanic rocks” the
weight is 1.
•Dominant
surface textural class and Dominant sub-surface textural class. If the codes for surface and sub-surface
textural class are “Fine” or “Very
Fine” than the corresponding weight is “1”.
