Water released by rainforests influences the water cycle of the entire planet. The amazon alone contributes to 20% of the world's oxygen through the process of photosynthesis. As the rainforest decreases, so does its ability to support the rest of the planet. Large forests absorb carbon from the atmosphere, slowing the pace of climate change.
Fires fires, often associated with broken electrical and gas lines, is one of the common side effects of earthquakes. Gas is set free as gas lines are broken and a spark will start bringing inferno. To complicate things water lines are broken and so there is no water to extinguish the fire.
Fire dynamics is the study of how chemistry, fire science, material science and the mechanical engineering disciplines of fluid mechanics and heat transfer interact to influence fire behavior. In other words, fire dynamics is the study of how fires start, spread and develop.
Effects of fire on flow and deposit effects of fire on down stream water are mainly shown in two aspects: increasing river flow and degrading water quality. The area burned, fire intensity, soil type, river size and geographical location all have influence on river de- posit and flow.
High levels of air and water pollution smoke and ash released during fires can pollute the atmosphere with toxic gasses and particles.

Fire is an intrusive disturbance in both managed and wildland forests and grasslands. It initiates changes in ecosystems that affect the composition, structure, and patterns of vegetation on the landscape. It also affects the soil and water resources of ecosystems that are critical to overall ecosystem functions and processes.
Positive effects of wildfires: • in a lot of thick forests, there is obvious overgrowth of trees, from the ground vegetation to high rising trees, hence resulting in more competition for soil nutrients and water. Surprising as it may sound, a forest fire is beneficial in providing fresh nutrients in the soil for a new generation of vegetation.

Aug 29, 2013 while the damage to vegetation and structures is an obvious impact of wildfires, a more hidden consequence are the effects on the region's water supply.
A water supply system is analogous to the human circulatory system. The heart pumps blood through the arteries, veins, and capillaries to supply oxygen to all part of the body. A water pump supplies water through primary, secondary, and distributor water mains to supply water to consumers and for fire protection.
Fire is a prevalent feature of many landscapes and has numerous and complex effects on geological, hydrological, ecological, and economic systems. In some regions, the frequency and intensity of wildfire have increased in recent years and are projected to escalate with predicted climatic and landuse changes.
What is weather? it is the state of the atmosphere surrounding the earth at a certain area. The atmosphere is a gaseous mantle (mostly oxygen and nitrogen) encasing the earth and rotating with it in space.
Fire is quite a common natural phenomenon closely related to forest hydrology in forest ecosystem. The influence of fire on water is indirectly manifested in that the post fire changes of vegetation, ground cover, soil and environment affect water cycle, water quality and aquatic lives. The effect varies depending upon fire severity and frequency.
Water is the agent of choice for structural fire suppression for many reasons: (11) the general ability of water from fire hydrants in communities that have a municipal water system. The general availability of water in suburban and rural areas without fire hydrant service from farm ponds, wells, small lakes, creeks, streams, and, in many.
As water travels through hot smoke, the temperature difference between the two will induce a heat transfer from warm smoke to cold water to meet an equilibrium temperature.
We assessed water quality of a 2 nd - and a 4 th-order stream in a single watershed for 5 monsoon seasons before, during, and after a catastrophic wildfire. Fire had significant and sustained long-term effects on both streams. In the 2 nd-order stream, variability in dissolved o 2 (do) increased after the fire.

Oct 9, 2017 wildfires change water quality, which could have consequences for marine life.
Water puts out fire by creating a barrier between the fuel source and the oxygen source (it also has a cooling effect which has to do with the energy required to convert liquid water into water vapor).
The effect of fire on water quality is dependent on how fire characteristics interact with watershed characteristics. Fire characteristics include frequency, intensity, duration, and spatial extent of burning (boerner, 1982). Watershed charac-teristics include weather, slope, soil type, geology, land use,.

Abstract: fire is a prevalent feature of many landscapes and has numerous and complex effects on geological, hydrological, ecological, and economic systems.
But scientists are warning that intense and repeated fires can damage the ecology of waterways by exposing them to the sun’s heat, exacerbating flooding and erosion along denuded hillsides, and releasing toxins such as mercury that are often liberated from soil and tree trunks.
A fire can impact both ecological health and drinking water operations. The large quantities of post-fire sediment can overwhelm the biological habitat available for aquatic organisms such as fish, as well as organisms that depend on water for some life stage, such as amphibians and insects.
Forest fire often directly affects water quality in nearby streams and other bodies of water.
“wildfire has a much greater effect on water supply than prescribed burning, because it consumes more vegetation and its heat alters the ground in a way that reduces the amount of water that can infiltrate during a rainstorm.
A wildfire, bushfire, wildland fire or rural fire is an unplanned, unwanted, uncontrolled fire in an many plant species depend on the effects of fire for growth and reproduction.
The impacts of wildfire on water quality in streams can be of shorter duration and quite different than in major water-supply reservoirs.
Despite the pronounced effect of fire on soil hydrological systems, information on the direct effect of fire on soil water retention characteristics is limited and contradictory. To increase understanding in this area, the effect of fire on soil water retention was evaluated using laboratory burning and heating experiments.
A steam explosion is an explosion caused by violent boiling or flashing of water or ice into steam, occurring when water or ice is either superheated, rapidly heated by fine hot debris produced within it, or heated by the interaction of molten metals (as in a fuel–coolant interaction, or fci, of molten nuclear-reactor fuel rods with water in a nuclear reactor core following a core-meltdown).
To sustain a fire, you need three factors: fuel, oxygen, and heat. Most of this removing heat is the evaporation - roughly 540 calories / gram, so 7x more heat than is needed to get water from 20°c to boiling (with a tip of the hat to @jasper for pointing out erroneous value in earlier revision of answer).
When faced with fire it is beneficial to know the ways to put out a fire and what types of fires can be put out with water. Just as there are different types of fires, there are different types of extinguishers: class a extinguishers put out common flammable materials such as wood, and paper.

Fires profoundly affect the abundant organic matter that contributes to surface soil structure and poro- sity.
Most critical effects occur if there is heavy rain soon after fire, as loss of vegetation and altered soil structure can make fire-affected soils more erodible.
Potential effects of wildfire on municipal water supplies and downstream aquatic ecosystems include the following: changes in the magnitude and timing of snowmelt runoff, which influence filling of water-supply reservoirs increased sediment loading of water-supply reservoirs, shortened reservoir lifetime, and increased maintenance costs.
If fire debris is not fully cleaned up, it can be flushed and transported into water bodies by rain. We hope for a rainstorm to help us contain the fire, but that rain can flush fire debris into water bodies. In addition, these fires can burn water infrastructure such as water distribution pipes, potentially cutting off access to clean water.
