Keetch-Byram Drought Index (KBDI)

What is Keetch-Byram Drought Index (KBDI)?

Keetch-Byram Drought Index (KBDI) meaning in Safety terms is

  • An estimate (0-800) of the amount of precipitation (in 100ths of inches) needed to bring the top 8 inches of soil back to saturation. A value of 0 is complete saturation of the soil, a value of 800 means 8.00 inches of precipitation would be needed for saturation. In the 1988 version of NFDRS, outputs of KBDI are used to adjust live and dead fuel loadings.
