“…Future research can build upon this comparative study by conducting a validation analysis using flood delineation from satellite imagery, similar to the work by Bernhofen et al (2018) or Hawker et al (2020) but for a larger set of regions across the world (e.g. using the recent Global Flood Database; Tellman et al, 2021). Future studies can also investigate how model agreement varies with the fluvial geomorphology of the rivers (e.g.…”

“…False Alarms are 31 while Misses are 0 at 0.14. If the weights are such that m/f = 5/4, then NDVI has two optimal thresholds at 0.089 and 0.11 where each threshold has a weighted cost of 9 1 4 times the cost of a square kilometer of False Alarms. If the weights are such that 5/4 < m/f < 23, then NDVI has one optimal threshold at 0.11.…”

“…Floods affect more people than any other natural hazard [1]. Remote Sensing is crucial for the mitigation of floods because remotely sensed images can quickly generate complete coverage of indices that distinguish between the presence and absence of water.…”

“…A Pacific Island example of this situation is illustrated by Reuben and Lowry. 2016 [65], who spatially analysed risk with respect to flooding for the extreme weather event in 2016, Honiara, Solomon Islands. In this case, the capital city was inundated by the flooding of the Mataniko River.…”
