2.2 Modification of original GALDIT method
GALDIT is a model employed for assessing the vulnerability of
underground aquifers to seawater intrusion using six parameters related
to seawater intrusion. Data about these six parameters were collected
and scored according to the criteria, and maps for the parameters were
generated by applying predefined weights. Scores of 2.5, 5, 7.5, and 10
were determined according to the criteria. The weight of four was
assigned to the index that had the greatest effect on seawater
intrusion, and the weight varied by the effect. The relationship between
the index according to the criteria and weight of the index is expressed
as follows:
