A scientific explanation of how floods occur
By: John Welford
Flooding of land and buildings causes enormous damage in many countries across the world, incurring vast expense as well as causing loss of life. Floods that occurred in England in 2007 led to 180,000 insurance claims, against which 3 billion pounds sterling was paid...

Floods constitute one of the easier environmental phenomena to describe. A flood is, in no uncertain terms, an excess of water hitting a particular location at one time. Water levels rise far beyond normal, and anything on the land that the flood is hitting is...

Floods are one of the most powerful – and deadly – forces on earth, claiming more lives in the United States than any other weather phenomena. It is vital to understand the scientific principles behind flooding so as to aid in their prevention and protect...

A flood is an overflow of water which temporarily covers land not normally covered by water. Floods occur whenever there is too much rainfall, meltwater, storm surge, or other release of upstream water for the rivers to handle and the ground to absorb within that...

Concern has been mounting for almost a decade as scientists hunched over their instruments and double-checked new data concerning the status of the Earth's crucial magnetic field.The magnetic field protects all life from damaging solar radiation. Exposure to such radiation can cause cancer and...

Flooding refers to the overflow or accumulation of water on land, which has the effect of submerging it. There are several known causes of floods – that are either natural or man-made. These include heavy or frequent precipitation, snowmelt, and land use. However, the causes...

Pyroclastic flows are the mixture of solid to semi-solid fragments and gases that flow down the sides of a volcano. They are in a fluidized form. They are heavier than air emulsions (suspension of a liquid in another liquid). When they are falling, they look...

Heavy rainfall is one of the most common causes of flooding. There are, however, several other events that can cause floods.When rain falls, it is either absorbed into the ground (infiltration) or flows along the surface of the ground (runoff). If the soil is...

Flood is defined as overwhelming of usually dry land by a large amount of water that comes from an overflowing river or lake, exceptionally high tide, melting snow or excessive rainfall [1]. Although this definition doesn't describe the mechanism of flood creation, it lists most...

The magma (molten rock) found in volcanoes contains dissolved gases. Magma deep beneath the earth's crust is under tremendous pressures. As the magma rises towards the surface there is a decrease in the pressure that the magma is under, and the gases will come out...
