Abstract
ABSTRACT Flooding is a regular danger in the Idukki district of Kerala causing serious damage to life and property. An attempt has been undertaken in this research to identify crucial zones in the Idukki district that are more susceptible to flooding. The AHP technique was used to give relative weights to 12 flood contributing parameters. The resultant flood susceptibility map shows that 1346.4 km2 of the total land in the Idukki district has a high to very high likelihood of flooding. Validation of the resultant map was achieved using the AUC-ROC approach, which showed good accuracy of 0.91.
