Urban Flooding: It Can Happen in a Flash!
Fort Collins in Colorado was hit by the worst flash flood in July 28, 1997 (Kelsch, n.d.). The heaviest rains ever witnessed in an urban area were experienced in this town. The flood caused the death of five people and the damage of property worth $200 million. It is believed that the rains lasted for up to 30 hours before a heavy downpour was experienced in the night of 28th July. This led to flash floods. The media labeled the flood as the 500-year event because of its magnitude which had never been felt in the recent years. Mathew Kelsch toured the area to meet the eyewitness of the flood to give what he saw during the night’s flood. The recorded trip, dubbed Urban Flooding: It can happen in a flash, gives a summary of the aspects of flash floods that happen in urban areas. This paper gives a summary of what was covered in the module. Heavy rains in urban areas can lead to urban runoff can lead to damages and even the death of people (Kelsch, n.d.). In Fort Collins, heavy rain was felt throughout the day. The intensity of rainfall increased in the night and lasted for one and a half hours. This led to peak flows across the whole town. This in turn led to much damage. For instance, Colorado University was adversely affected by the flows (Kelsch, n.d.). This incident has shown that the weather patterns that lead to flash floods cannot be easily predicted since they could happen suddenly. In the case of Fort Collins, hot and dry weather was experienced six weeks prior to the floods (Kelsch, n.d.). Humidity increased towards the end of July. On the 27th, a strong cold moving towards the south was experienced. This is believed to have triggered storms to form in the northern Colorado in the afternoon of the Sunday of 27th July (Kelsch, n.d.). An account of how the storms started before increasing in intensity further shows how flooding cannot be easily predicted. The storms...
