<br />In researching past flood events, it has been found that the severity of flooding is directly related to the
<br />level and intensity of the available moisture and other atmospheric conditions. The causes of floods relate
<br />directly to the accumulation of rainfall runoff, rapid snowmelt, the failure of man-made structures, such as
<br />dams and levees, or a combination of any of these events, The following table entitled 'Major Floods in
<br />Colorado' presents the date, stream or location of the flood: the type of event: the number of deaths it
<br />caused: and the damage totals in 1998 dollars, The acronyms for the types of events are detailed below:
<br />. General Rain Floods (GR)
<br />. Thunderstorm Floods (TS)
<br />. Snowmelt Floods (SM)
<br />. Rain or Snow Floods (RS)
<br />. Ice Jam Floods (IJ)
<br />. Dam/Levee Failure Floods (OF)
