An archive number is assigned to any flood that appears to be "large": significant damage to structures or agriculture, long intervals since the last similar event, and/or fatalities
*Severity Class
Class 1: large flood events: significant damage to structures or agriculture; fatalities; and/or 1-2 decades-long reported interval since the last similar event. 
Class 2: very large events: greater than 20 yr but less than 100 year recurrence interval, and/or a local recurrence interval of at 10-20 yr.
Class 3: Extreme events: with an estimated recurrence interval greater than 100 years
**Flood Magnitude = ln(duration) * severity class * sqrt(affected region)/100 {if duration=1, then duration is set at 1.1 for this calculation.}
