Inside the Colorado deluge

Inside the Colorado deluge | Geography Education | Scoop.it

"Two things that helped make this rainfall historic are breadth and duration. Colorado can get much higher rainfall rates for brief periods and over small areas."

Seth Dixon's insight:

Our thoughts are with our colleagues and friends in Colorado as they are dealing with the impact of this historic weather event.  The geographic factors that contributed to this flooding are explained in this article from the University Corporation for Atmospheric Research (UCAR).  Some are calling this a millennial flood, as it is well past the 100-year stage of flooding.  You may view the areas impacted on an ESRI storymap. and in this NASA imagery

The devastating flooding in Colorado has impacted so many. The rainfall Colorado has experienced makes it the most on record. The massive amounts of flooding and devestation in areas like Boulder are caused by the highly populated valley areas.

Almost seems like a perfect storm scenario.  Large amouts of rain over a long perod of time over a large area.  This combined with a late summer/early fall heat wave and tons of moisture in the air, with climate change all contributed to the disater in Colorado.  They also believe the changes made by people to the physical geography over the last hundred years or somade have contributed to teh flooding in the area.  Development can effect the way a place floods.  Where there were once open fields and trees, there are now parking lots and houses which just can't absorb rainfall.  Makes you ask the question, shouldn't there be more study of where we exapnd our cities and what effect this will have in case of a major rainfall, earthquake, blizzard, etc?

      What was interesting about this particular deluge was how much rain fell and how it happened in such a short time. Meteroligist high wet density levels of vapor that rose to high altitutdes and was able to condense into water and help in a perfect combination of weather to create a powerfully dangerous flash flood.

    The article recounts a former major colorodo flood that occured in 1978 and had killed over 150 people during a centenial celebration.

   After this occurence warning signs were put up beside the roads to warn travelers of flash flood possiblities and to promote safety. These floods do not happen in Colorado often and are usually a surprise. They do not when the nextmajor flash flood may occur in the boulder region but they know through historical patterns that it will happen again. 

This article stood out to me because I have friends that live in these areas and had to run for safety and move their cars to prevent damage in these same areas. The good thing is that the people that I know from this area are doing ok.
