Recording Flood Inundation Extent

Flood extent recording is time-critical. An extent map without a timestamp relative to the flood peak has limited value.

9 of 10Method note

Overview

  • Record capture time and the nearest gauge reading; extent without stage is not interpretable.
  • Extent is a maximum-observed extent, not a maximum possible extent — label it that way.
  • Vegetation and turbidity hide the water edge; state the expected boundary uncertainty.
  • Align the output to the flood agency's own reporting units.
