The KBDI is an estimate of the soil moisture deficit, which is the amount of water necessary to bring the soil moisture to its full capacity. A high soil moisture deficit means there is little water available for evaporation or plant transpiration. [2] This occurs in conditions of extended drought, and has significant effects on fire behaviour.
The Palmer drought index, sometimes called the Palmer drought severity index (PDSI), is a regional drought index commonly used for monitoring drought events and studying areal extent and severity of drought episodes. [1] The index uses precipitation and temperature data to study moisture supply and demand using a simple water balance model.

The GPCC drought index provides SPEI datasets at a 1.0° spatial resolution for limited timescales (1, 3, 6, 9, 12, 24, and 48 months). [5] Inputs to SPEI datasets can include high-resolution potential evapotranspiration (PET) from the Global Land Evaporation Amsterdam Model (GLEAM) and hourly Potential Evapotranspiration (hPET). GLEAM is a set ...
whereas high WUE plants could correspond to a drought avoidance/water saving strategy, through drought-sensitive, early closing stomata. Increases in water-use efficiency are commonly cited as a response mechanism of plants to moderate to severe soil water deficits and have been the focus of many programs that seek to increase crop tolerance to ...
The Universal Soil Loss Equation (USLE) is a widely used mathematical model that describes soil erosion processes. [1]Erosion models play critical roles in soil and water resource conservation and nonpoint source pollution assessments, including: sediment load assessment and inventory, conservation planning and design for sediment control, and for the advancement of scientific understanding.
Communication of the science of how water systems work is an important aspect when creating a management plan to conserve that system and is often used for ensuring the right management plan to be put into action. [11] The conservation of water is extremely important in order to preserve wildlife habitats.
The U.S. Drought Portal also aggregates and presents drought impact data for economic sectors such as agriculture, energy, water utilities, and recreation using interactive maps and data. [11] The NIDIS Program is supported by the NOAA Climate Program Office and is housed at the NOAA Earth System Research Laboratories in Boulder, Colorado.
