KBDI Report Archives
This is the front end for the KBDI Archives.
KBDI records as far back as three years ago today are available.
The Keetch-Byram drought index (KBDI) is a continuous reference scale for estimating the dryness of the soil and duff layers.
The range of the index is determined by assuming that there is 8 inches of moisture in a saturated soil that is readily available to the vegetation.
