You can find a better/more detailed description in most any hydrology textbook. Hope this helps!
RE: 100 Year Event
The result was overtopping by 0.25'.
I increased the road grade elevation by 0.30' and reran the HY8.
The result was now overtopping by 0.24'.

RE: 100 Year Event
One thing to keep in mind is that a 100-yr rainfall event does not automatically mean you will have a 100-yr flood, so be careful in how you make application of the rainfall data.
