Can Flash floods become a tool for the power of nature to avenge on people?

Flash flood causes destruction that threatens the life of the people and ruin land properties like a single attack of deadliest Tornado in US history. This is a great power of the environment to revenge on human beings who are kept on destroying the forests converting fields and mountains to industrialized houses or buildings. During flash floods, rapid water overflowing that came from the rivers, ocean or sea, lakes and other bodies of water, which causes the land erosion, landslide and many other damages causing the loss on properties as well as life of some people. The only difference between a regular flood and a flash flood is the timescale which the regular flood easily subsides in less than six hours while flash flood rushes and exceeds more than such hours. Flash flooding occurs and causes the runoff of large volume of water in low areas, rapidly rushing down the hills. Areas close with volcanoes may also experience the flash floods after the volcanic eruption. You might ask in comparison through asking Is super volcano a fearful threat for the destruction of the earth and humanity?” Also, it may happen when the glaciers melt down during too much global warming or hot weather. This surge of water usually occurs in US mountain ranges along with the arid plains in southwestern part of America. Other human activities can trigger flash floods such as dams which suddenly destroyed with hydro-electricity, large quantities of water and causes damage in everything within its footpath.

Frequent flash floods that exist in America lead the government’s National Weather Services to alert the people to evacuate and transfer in a safer place due to dangerous flash floods that drown and kill the people. Flash flood is not a simple disaster but due to its sudden water’s current and it’s rush nature, it never choose to kill and damage properties. More than 50% of the fatalities in US became the victim of such event. This incident usually happens when the people underestimate the flash flood’s ability, specifically the real capacity of flash floods to ruin their lives and properties. Others dare to cross the prohibited section of flooded areas which many people had injury while others died during the strong rush of water. The report of National Weather Service on 2005 with an aid of the data in an average of 30 years national record revealed that many people died annually due to flash floods or regular floods with an average of 127, while lightning got 73, tornadoes is 65 and hurricanes has 16.

Flash flood events in desert is very dangerous and deadly since storms seldom visited arid regions and when it happens enormous volumes of water can blast over a short span of time yet causing runoff rivers or rushing water from high region going to low lands and water is hard to stop because the rains due to such storm fall on land with poor water absorption, often its texture is like a clay and it can’t help speed up the water to lessen, thus waters continue to move on any low parts of the areas, causing many places suffer from high water level, damaging the place itself, and other things along its path. Strom drains, retention basins worsen the scenario and properties of people are also ruined along with injured and dead people. Desert roads are always crossing the rivers during dry season but when storm strikes it affects so much the transportation and life of the people living on such place. Finally, irregular down pour of rain on water channels which takes the large amount of water causing the desert people to suffer from deserts debris composed of logs, mud clay and rocks. This is how great the power of nature far more to destroy the humanity when it avenge like the things happened when the sixth deadliest earthquake in history when claims its rule to remind the people on their evil activities.
