Flood Recurrence Interval: Chowan Basin |
||
|
||
Scientists
map the areal extents of floods and assign recurrence intervals
using streamflow data collected by the USGS and the Virginia
Department of Environmental Quality since the late 1800s. Recurrence
intervals express the likelihood that an event, such as a
flood, will occur in any given year. For example, a
100-year-flood has a 1% chance of occurring in any year, and a
25-year flood has a 4% chance of occurring in any year. |
