Wednesday Week Nine

...some questions...

1. Why did I take so long introducing the two OLOs that I can't talk about together here?

2. What is a flood? Can we just define it as a rare, high-water event? What is the does the default method for reporting streamflow conditions by the USGS? Is this an effective mechanism for defining a flood? What method is used by the National Weather Service? According the NWS, location-specific definition, has there been a flood on the Maury River at BV in the past 356 days? Has there been anything even close to a flood? What about the Maury River at Rockbridge Baths? Why is there a difference? What metric does FEMA use when defining a flood?

3. What is a FEMA Flood Insurance Rate Map? What is the gist of the agreements between the local authorities that are responsible for zoning (building) codes and the US federal government? Why is this important?

4. What is a recurrence interval? How is it calculated? What are the two possible definitions of a 100-year flood? What is the relationship between recurrence interval and discharge?
