The Stability

In east-facing canyons in the coastal mountains of California, the daytime thermal up-canyon winds are frequently replaced, usually in early afternoon, by a moderately strong down-canyon wind. The same type of wind has also been noted in the western foothills of the Sierra Nevada. This shift in the wind to down canyon is important in wildland fire control and has been a factor in some fire-fighting fatalities. Results of a fire-climate survey conducted in northwestern San Diego County to study these winds show that, in the summer and early fall of 1959, winds switched to down canyon in the afternoon on about one-quarter of the days. From the surface records and a few double-theodolite and airplane observations, a diagrammatic model of this phenomenon has been constructed. The stability of the lower atmosphere along the coast was closely related to the occurrence of down-canyon winds in the area studied. The possibility of making short-range predictions exists by using this relationship along with other considerations.

Fire Containment

We describe a mathematical model for the probability that a fireline succeeds in containing a fire. The probability increases as the fireline width increases, and also as the fire's flame length decreases. More interestingly, uncertainties in width and flame length affect the computed containment probabilities, and can thus indirectly affect the optimum allocation of fire-fighting resources. Uncertainty about the fireline width that will be produced can often affect containment chances as much as uncertainty in flame length.

Hydrological Characteristics

Wildland fires frequently happen and develop in hard-to-reach regions, fast covering large areas due to the presence of ignitable matters together with beneficial meteorological circumstances. Human actions and natural events are the main reasons for the appearance of wildland fires. Our study focusses on the idea of using natural resources, namely water assets on the fire-affected territory. Since fire suppression is primarily performed with water, the provision of sufficient water sources in the proximity of the burning area is critical. An investigation of the hydrological characteristics of the territory is needed, especially in the driest months, when most of the wildfire events are expected to occur. The construction of a support point for fire-fighting water supplies in the wildland territories is also a requirement for building a network of water assets in the wildland territories.
