This code calculates the Geomorphic Flood index (GFI), a descriptor of basin's morphology. It was recently formulated with the specific aim to represent a metric for the flood hazard. The work of Manfreda et al. (2015) and Samela et al. (2015; 2016) showed that a linear binary classifier based on the recently proposed Geomorphic Flood Index (GFI) exhibited high classification accuracies and reliability in several tests, and is able to provide reliable flood inundation maps in data-scarce regions and for large-scale applications.

The code really works fantastic. I found GFI performed much better than AHP-Weighted overlay method for flood-prone mapping.

Of course, thank you for your interest! I do not think I can upload them here. Please contact me on and I will be happy to share the data.
