Summary
The Flood/Water Extraction Index (FWEI) is a water spectral index intended for multispectral sensing. It was introduced in 2024; its source is cited as Hadi Farhadi, Hamid Ebadi, Abbas Kiani, & Ali Asgary (2024). A novel flood/water extraction index (FWEI) for identifying water and flooded areas using sentinel-2 visible and near-infrared spectral bands. Stochastic Environmental Research and Risk Assessment, 38(5). https://doi.org/10.1007/s00477-024-02660-z .
Based on the latest citation data, this index is in the 14.83th percentile overall, ranking 272 out of 317 indices with citation data. Among the 31 indices published within two years of 2024, it ranks 4 (90.32th percentile). Within the water application domain, it is in the 25th percentile and ranks 25 out of 32 indices with citation data. Among the 6 similarly aged water indices, it ranks 2 (83.33th percentile).
