Various Wildfire Supression Techniques

In the US before 1910, forest fires were considered part of the natural environment (week 2013). However, according to Weeks (2013), the situation has changed when a large area of ​​land was destroyed by a fire occurring in Montana State and Idaho State and 87 people died. The restraint technique used after this leads to excessive accumulation of grass and leads to a larger wildfire (Weeks 2013). As quoted by Weeks (2013), Stephen Pine, who is studying the historical influence of forest fires, says, "The elimination of a sudden fire is a serious cultural and ecological event that is as serious as the occurrence of a sudden fire It is "

Suppression of forest fires depends on technology available in the field of forest fires. In developing countries, you can use as simple a method as throwing sand and burning fire with sticks and palm leaves. In more advanced countries, how to suppress depends on technical capacity. Silver iodide can be used to promote snowfall while flame retardants and water can be placed on fire through unmanned aerial vehicles, planes and helicopters. Complete extinguishment is no longer anticipated, but most wildfires are often erased before they lose control. It contains 99% or more of 10,000 new wildfire every year, but it is difficult to suppress wildfire escaping under extreme weather conditions without changing the weather. Wildfire in Canada and the United States burns an average of 54,500 square kilometers (13 million acres) per year.

Wildfire modeling involves numerical simulation of forest fires to understand and predict fire behavior. Wildfire models are designed to help suppress wildfires, increase the safety of firefighters and the public, and minimize damage. Using computational science, forest fire modeling involves statistical analysis of past fire events and predicts location risks and state-of-the-art behaviors. Various wildfire propagation models have been proposed in the past including simple oval, oval and fan shaped models. Early attempts to determine wild fires behavior assumed the uniformity of terrain and vegetation. However, the precise behavior of the wildfire striker depends on various factors including wind speed and slope. The modern growth model uses a combination of the past ellipsoid description and Huygens' principle to simulate flame growth as a continuously expanding polygon. Extreme theory can also be used to predict the scale of large wildfires.

Wildfires These fires burned plenty of forests and brushes. When they are outrageous, forest fires can destroy homes and become potentially fatal. In recent decades, the number of large wildfires and seasons of forest fires has increased. Let's learn how climate change exacerbates the situation of forest fires. The weather refers to the state of the atmosphere from a few minutes to a few days. There are lots of familiar things such as temperature, humidity, rain, snow, wind speed, wind direction. The climate is the long-term average (and other statistics) of the weather measured over a long period of time (at least decades).
