loop above. Below is zoomed ILN N0Q
hi-res radar station at Wilmington OH, Wundergages, and
adjusted N0Q at watersheds. Note that the raw N0Q radar here almost always
shows "ground clutter" because of being so close to the radar site. Ground
clutter (0.02" to 0.05" a day) is just another simple matter that rain gage
adjustment removes. No rain at the rain gages for the hour then no radar rain.
The 63.2 sqmi MassiesCreek basin was not subdivided and the USGS gage is
03241500 Massies Creek at Wilberforce, OH. The basin boundary was digitized using
Google Earth Pro Add Polygon method and saved as a KML file. My
GoogleKML2Text.exe program then converts the kml to text for my
LatLongPixelsFromFile.exe that creates the GetRealtime basin boundary pixels.
These programs are free on my Help web page from the top menu above.
The NWS and USGS does not provide flood stage info so I used the 5 yr, 10 yr, 50
yr and 200 yr flood frequencies from my Log Pearson frequency curve and
interpolated in historical flood stages.
Annual peak FLOWS are also provided since 1953 and I created a Log Pearson III
annual propability distribution of the peaks for use for reporting peak flow
recurrence in GetGraphs. I also got the NOAA Atlas 14 partial probability rainfall
depths for reporting the 5-min to 3-day recurrence of rain depth.
