There is a wikipedia article on the Boscastle Flood of 2004. This was a flash flood event, caused by simultaneous water discharge from several catchments, though land clearances and engineering works no doubt played their part as well.
One rainguage recorded 3.5 inches of rain within one hour, but many others in the region showed less than 0.5 inches.
Like most flash floods, debris dams formed, and upon their breeching, a flash flood followed downstream.
That is some rainstorm! The heaviest rainfall on earth is only around four times that - in a whole year! The answer is 17.1875 inches.
Rain that fell and filled up one centimeter of the ground
2 inch/hour divided by 60 mins/hr = 1/30 inch per minute 1/30 times x minutes = rainfall in x minutes = x/30
5 mm?
In a year, no. In an hour, possibly - specially if in an area that is not used to much rain.
On August 16, 2004, Boscastle, Cornwall experienced a flash flood caused by heavy rainfall. In just two hours, over 200 mm (7.9 inches) of rain fell, leading to widespread flooding and significant damage to the area.
21 feet of rain
1,000,000cm
they mostly start when there has been lots of rain
202mm, but then the rain went into the river near by and then that would have made even more. the flood was crazy but i visited Boscatle in 2010 and you wouldn't believe how well it has been rebuilt. Also one months amount of rain fell in at least 2-3 hours! (hope this helps)
So you can see how much rain fell that day when it rained!
we need 15 rambillion inches of rain to get out of the drought.
50,000 inches
i love green clouds.
The Boscastle flood started in 2004 by torrential rain and the river Jordan burst its banks. It was also caused by snow melting, due from the winter. The rain helped the snow melt and the river to burst, therefore, caused a flood
The rain, It rained heavily for a long period of time, (Prolonged Rain) , it rained an exceptional amount of rain in 8 hours, 2 inches in 2 hours. as well as that, deforestation, and the fact that the soil was saturated deforestation is when trees are cut down. when they are cut down theres nothing to suck of the water from the ground (roots) and no leaves to catch the water interception
Boscastle is found where two valleys meet, formed by the rivers Valency and Jordan. A third river, Paradise, also flows through the village.
