Getting Started with Nashville Example Rainfall Runoff (Zip 9 MB)--Fully operational project example
for radar rainfall, adjustment, and runoff computations for 3 subs at Nashville,
TN with Hec HMS, RAS and EPA-SWMM projects. Unzip the download to C:\ where the
folder C:\GetNashville will be created and
read the file READ_ME.txt.. After getting this project working then you
can copy it and convert it to your basin of interest. And here is a fully
operational SNOWMELT setup
example in New York. More questions, see
next Start Here!
Getting Started with Radar Rainfall--Steps for downloading and installing
needed programs for radar rainfall and adjustment. Get started here.
See

really how it's done. More questions, see next Start Here!
Getting
Started with
Radar Rainfall Runoff Setup Example Harvard
Gulch--A concise step by step quide to setups for using GetRealtime radar rainfall and
runoff (top half). More questions, see Help! at top.
Getting Started with Snowmelt
(Zip 9 MB)--Fully operational project example in New York
I'm using winter and summer. If the radar over shoots and leaves you
high and dry... just set the midnight snow water equivelant from heated gages or
NOAA swe and let the melt or rain on snow proceed... and shell Hec-Ras for ice
jams I guess.
Example
Simple Single Rain Gage Adjustment Evaluation (Zip 13 MB) all inclusive setup.
I did this to compare forecasts using NWS, HRRR, and Radar Nowcasts for Hurricane Florence of
Sep 2018. If all else seems overwhelming just install GetRealtime and then
forget about that install and unzip this to C:\GetProjects\ to see a much
simpler setup. Just remember a single gage adjusted POINT radar BETTER look just
like the gaged rainfall. Also I have a -3 hr Pacific time zone shift in
NWS Forecast in GetRealtime_setup.txt and the rain gage in table 'rsite'.
---------------------------------------------------------------------
Case studies in real-time
(GetRealtime has been improved over the years as reflected in these
studies, so be sure to check out the latest results near the bottom of
each web page... actually it's the input rainfall that's been improved.)
---------------------------------------------------------------------
 Radar Rainfall
Ajustment, Charlotte, NC--Confidence building using 3 Wundergages
to adjust radar rainfall at 6 USGS rain gages and an adjusted basin runoff
comparisons. Also includes comparison of super res Level 2, Composite N0Q, and good ol' N0Q... yes, N0Q cleans their clock... I hope!
Study completed in 2013 but is still an important read.

3-hr NOWCAST Comparisons from around the USA--Gallery of ongoing comparisons
of
Nowcasts using Lagrangian frame of reference by moving subbasins upwind
each 5 minutes on last radar image to see how well they work... or not.
Includes NWS 7 day and HRRR 18 hour.

NWS Snowcasts of Melt and SWE Comparisons to GetRealtime from around the USA--Gallery
of ongoing comparisons of the NWS forecasts of SWE and Melt to GetRealtime
snowmelt computations (and has already let to improvements in GRT).
54 sqmi Rapid
Creek above Canyon Lake Dam, SD--5 subbasins combine with
scheduled realease from upstream Pactola Dam.
23.9 sqmi Willow Creek
nr Crooks, SD--Another high plains GetRealtimes gage adjusted radar
rain and snowmelt for real-time continuous operation and forecasting. These
basins on the high plains have extrememly long peak rain to peak runoff times,
20 hours for a 23 sqmi basin. Maybe its groundwater lag with all the
sand or something???
63.2 sqmi
Massies Creek
nr Wilmington, OH--Another close to radar GetRealtimes gage
adjusted radar rain and snowmelt for real-time continuous operation and
forecasting in Ohio. Single subbasin with GetRealtime snowmelt method.
Quick Setup for Urban
Nashville, TN--Let see how GetRealtime does in Tennessee with minimal effort
on my part. Listed are my notes needed to quickly set this basin up, the
adjusting Wundergages, and to subdivide it. Includes a quick look at the
frequencies of the epic May 2010 radar.
Flood control reservoirs at Houston, TX--Reservoir storage
release ratings were constructed for 2 flood control reservoirs on Buffalo Bayou
above Houtson actively operated using Hurricane Harvey 30", 2000 year(?) rainfall with current flood
relase forecasts.
168 sqmi Bear Creek
below Ashland, OR-- Nexrad 5-Minute Radar Rainfall/Snowmelt-Runoff Comparisons in Real-Time With Radar1-HR Ratio Adjustments
and Contiuous SCS Curve Number Soil Flood Potential. Updated routings for
automated scheduling of dam releases and canal diversions for
active operations for an irrigation district.
40 sqmi
Mill Creek at Dalton, GA-- Nexrad 5-Minute Radar Rainfall-Runoff Comparisons in Real-Time With Radar1-HR Ratio Adjustments
and Contiuous SCS Curve Number Soil Flood Potential. Shows reservoir
operations for 2 reservoirs not actively operated.
Runoff Comparison
in San Joaquin Valley, CA--Comparisons of Nexrad radar generated area
averaged rainfall and snowmelt runoff with a USGS stream gage in San Joaquin
Valley, CA. Study Part 1 ended 5/18/2011. Part 2 added snowpack/melt but ended
with a Snafu and a Fubar. Part 3 winter 2013 redeems Snafu and Fubar using hourly
adjusted radar and continuous SCS loss methods. Study continues and
includes the NWS 7-day hourly weather forecast and 3-hour Nowcassts for computation of projected
rain/melt and runoff.
114 sqmi
Oneida Creek at Oneida, NY-- Snowwpack &
Melt/Rainfall Runoff Comparisons in Real-Time. Study started again Oct 1,
2017 using A2M multi-radar multi-sensor 2-minute rain rates for
winter snowfall to see if no adjustment and less overshoot can be found. Like
all other NWS precip products, A2M was once again found to be a complete dud
here.
114 sqmi
Oneida Creek at Oneida, NY-- Nexrad 5-Minute Radar Snowpack &
Melt/Rainfall Runoff Comparisons in Real-Time With Radar1-HR Ratio Adjustments
and Contiuous SCS Curve Number. Study ended with Nexrad Product dual pol.
Total Rainfall PTA a complete dud. Also the NWS runoff forecast had
forecast zero rise in stage while GetRealtime was showing Major flood stage
because of Nowcasts and just plain way better rainfall than NWS - PTA.
Large 610 sqmi Burro Creek
Basin nr Bagdad, AZ was subdivided to see if runoff computations
could be improved for this dry desert basin with some winter snowpack using N0Q
and NCQ. Because of bad results due to distance from radar sites and few
rain gages, radar product PTA storm total was tried without success so now
multi-radar multi-sensor product A2M unadjusted rainfall rate
wasevaluted and FAILED.
80 sqmi
Napa River above St Helena, CA-- Nexrad 5-Minute Radar Rainfall-Runoff Comparisons in Real-Time With Radar1-HR Ratio Adjustments
and Contiuous SCS Curve Number Soil Flood Potential. Shows reservoir
operations for a reservoir not actively operated.

area averaged rainfall runoff with a USGS stream gage and tipping bucket network
in Las Vegas Valley, NV. Includes adjusted radar rainfall error
comparisons at the tipping buckets.
Web Automation
Demo--Demonstrates GetRealtime's automation in real-time web
dissemination of runoff and forecasts imagery using the large and complex
Tallapoosa River Basin at Harris Dam, AL. Let's see if we can simplify
things and tame this big beast with radar.
Runoff Computations
for Maurice River NJ--A temporary setup example for the swampy Maurice
River near Norma, NJ.
Rainfall Comparisons
Blue Ridge Mtns, NC--Comparisons of 3 simultaneous Nexrad radar sites

Wunderground Evapotranspiration computations and Nexrad radar generated
point and area averaged rainfall at irrigated farm districts of the sunny
southwestern deserts (and an African example).
Rainfall Comparisons--Comparisons of Nexrad radar generated
point rainfall amounts with tipping bucket rain gages. Includes
hypothedical peak runoff comparisons for those foolishly daring to go beyond
daily rainfall totals (this aint pretty). Study ended 5/18/2011.

How To Videos on Youtube..
These Youtubes were made before the great N0Q reflectivity
images became available and so where ever it says N0R, I really mean N0Q!!! And
always use Lat/Long scaling, and convert to radar pixels with
LatLongPixesFromFile.exe, Lat/Longs can be really useful later. And
always - negative dsids for radar and +dsids for gages... unlike the
videos.
