Wildland fire behavior is affected by weather, fuel characteristics, and topography.. Weather influences fire through wind and moisture. Wind increases the fire spread in the wind direction, higher temperature makes the fire burn faster, while higher relative humidity, and precipitation (rain or snow) may slow it down or extinguish it altogether.
The last two components are the rate of fire spread if fuel is available for combustion, and the frontal fire intensity. [2] The essential information needed to calculate this index is: the humidity of the air at the beginning of the afternoon (when it has its lowest value); the temperature in the middle of the afternoon (when it has its ...

Wildfire debris (ash and sediment) clog rivers and reservoirs increasing the risk for floods and erosion that ultimately slow and/or damage water treatment systems. [180] [181] There is continued concern of fire retardant effects on land, water, wildlife habitats, and watershed quality, additional research is needed. However, on the positive ...
Simplifying these requirements may seem like sensible policy in fire-prone California, but opponents of SB 610 say the plan to abolish the ranking system unnecessarily seizes control from local ...
It became necessary to establish a national system for estimating Fire danger and fire behavior to improve and simplify communications among all people concerned with wildland fire. Work on a national rating system began in 1959. By 1961, the basic structure for a four-phase rating system had been outlined and the fire phase (spread phase) was ...

The applications of Hydrological Ensemble Predictions span across large spatio-temporal scales ranging from short-term and very localized predictions to global climate change modeling. HEPEX is organised around six major themes: Input and pre-processing; Ensemble techniques and process modelling; Data assimilation; Post-processing; Verification
