Flash Flood Potential Calculator

Estimates the likelihood of flash flooding based on rainfall intensity, soil saturation, and topography.

Before you use this tool

Use this if

  • Estimates the likelihood of flash flooding based on rainfall intensity, soil saturation, and topography.
  • You want a calculation that exposes its formula: Risk Index ≈ Rainfall Intensity * Soil Saturation Factor * Topography Factor (This is a simplified example. Actual formulas are more sophisticated.)
  • You already have Rainfall Intensity, Soil Saturation, Topography values to enter.

Skip this if

  • You need an official emergency alert or life-safety instruction.
  • You need a certified professional forecast instead of a calculator estimate.
