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 15.34th percentile overall, ranking 266 out of 313 indices with citation data. Among the 30 indices published within two years of 2024, it ranks 3 (93.33th percentile). Within the water application domain, it is in the 25.81th percentile and ranks 24 out of 31 indices with citation data. Among the 5 similarly aged water indices, it ranks 1 (100th percentile).
