Detecting Site Waterlogging and Drainage Clues

Waterlogging detection is a temporal problem: ponding appears and disappears within hours, so the flight time matters more than the resolution.

8 of 10Method note

Overview

  • Fly after the rain event, not on a fixed schedule — the window is short and predictable from the forecast.
  • Standing water over a surface with visible reflection is easier to screen than water under vegetation or on bare earth.
  • Distinguish ponding, saturated ground and wet sheen; they imply different drainage conclusions.
  • A time series across several events is more useful than one high-resolution flight.
