There Are Two Organizational Problems That Can Cause New-product Disasters. One of Them Is
Floods are second merely to fire as the near common of all natural disasters. They occur almost everywhere in the earth, resulting in widespread damage and fifty-fifty death. Consequently, scientists take long tried to perfect their ability to predict floods. So far, the all-time that scientists can practise is to recognize the potential for flooding in certain weather condition. There are a number of conditions, from deep snow on the ground to human error, that cause flooding.
When deep snow melts information technology creates a big amount of water. Although deep snow alone rarely causes floods, when it occurs together with heavy pelting and sudden warmer weather it can pb to serious flooding. If there is a fast snowfall melt on acme of frozen or very moisture footing, flooding is more probable to occur than when the ground is non frozen. Frozen ground or ground that is very wet and already saturated with water cannot blot the additional water created by the melting snow. Melting snow besides contributes to high water levels in rivers and streams. Whenever rivers are already at their total chapters of water, heavy rains will result in the rivers alluvion and flooding the surrounding land.
Rivers that are covered in ice can too lead to flooding. When ice begins to cook, the surface of the ice cracks and breaks into big pieces. These pieces of water ice move and float down the river. They tin form a dam in the river, causing the water behind the dam to rise and flood the land upstream. If the dam breaks suddenly, and so the large amount of water held behind the dam can inundation the areas downstream too.
Broken ice dams are non the only dam problems that can cause flooding. When a large human-made dam breaks or fails to hold the water nerveless backside it, the results can be devastating. Dams contain such huge amounts of water behind them that when sudden breaks occur, the destructive force of the water is like a great tidal wave. Unleashed dam waters tin can travel tens of kilometres, cover the ground in metres of mud and debris, and drown and crush every thing and animal in their path.
Although scientists cannot always predict exactly when floods will occur, they do know a great deal nigh when floods are likely, or probably, going to occur. Deep snow, ice-covered rivers, and weak dams are all strong conditions for potential flooding. Hopefully, this knowledge of why floods happen can help us reduce the damage they crusade.
