4 days ago · Keetch-Byram Drought Index (KBDI) is an index used to determining forest fire potential. The drought index is based on a daily water balance, where a drought factor is balanced with precipitation and soil moisture (assumed to have a maximum storage capacity of 8-inches) and is expressed in hundredths of an inch of soil moisture depletion.

The Keetch-Byram Drought Index (KBDI) assesses the risk of fire by representing the net effect of evapotranspiration and precipitation in producing cumulative moisture deficiency in deep duff and upper soil layers.

3 days ago · 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 …

The Keetch–Byram drought index (known as KBDI), created by John Keetch and George Byram in 1968 for the United States Department of Agriculture's Forest Service, is a measure of drought conditions. It is commonly used for the purpose of predicting the likelihood and severity of wildfire.

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.

Mar 5, 2025 · Keetch-Byram Drought Index (KBDI) is an index used to determining forest fire potential. The The WFAS website contains a variety of fire danger information including: Daily fire danger maps using National Fire Danger Rating System values from Weather Information Management System.

The KBDI attempts to measure the amount of precipitation necessary to return the soil to full field capacity. It is a closed system ranging from 0 to 800 units and represents a moisture regime from 0 to 8 inches of water through the soil layer.

The Keetch-Byram Drought Index (KBDI) is a drought index calculated by the Oklahoma Fire Danger Model. Ranging from 0 to 800, the index is used to increase the amount of dead fuel available to the fire.

The Keetch-Bryam Drought Index (KBDI) is one of the few daily indices used to monitor drought. It is most often utilized in the wildfire community, for it can give a real-time indication of the drying potential for the finer fuels such as grasses and shrubs.
