1)  GetRegression.xls--(revised 1/2/2015)  MS Excel menu macro for quickly computing/graphing regressions, interpolations, and probability distributions on any Excel sheet.  Includes Y=a(X-e)^b used in sediment and streamflow ratings where 'e' is the offset or point of zero flow. 

2)  ProbabilityGraphs.xls--MS Excel workbook for creating probability charts.  You might not have use for this xls if you added the the above GetRegression.xls to your Excel Menu bar.... but I could be wrong.

3)  Great Looking Excel Tips--Examples and videos for creating most excellant Excel spreadsheets by a pro at CSU.  I attended one of his workshops years ago and it opened my eyes to the world of Excel.

 Darrell G. Fontane
Beginners to experts will find his stuff  very useful and for adding that finishing touch.  Be sure to play the video links over on the right of his web page.  Dr Fontane will be adding more examples soon as his work load allows so stay tuned.  MS Office 2003 users can still open his downloads.  Just follow his tip at the top and Excel will prompt you do install a free update for reading 2007 files.

3) Excel Example with GoalSeek/Tips--Example worksheet using a command buttton and Excel's built in GoalSeek to solve Mannings flow equation area given flow from the Rational runoff method.  Tips include function Index() for looking up values for culvert sizes in stock.

Ok, so I'm no Dr. Fontane...

4) GetMapArea.exe 4.0.0--Defines drainage area boundaries and stream lengths with centroids on free topo map screens.  Reads topo maps from Google Maps in full screen mode as a menu selection for dislplay and determination of Lat and Long.  Also try the full screen USGS map viewer option in GetMapArea with Content, Base Data Layers = Hydrography checked.  It's very buggy. Do not set scale with the scale legend, add 'Scanned topo' with 6 mile township or 1 mile section lines.  Better yet, use the map viewers 'Find Coordinates' on it's tool bar to get diagonal Lat/Long scaling points, then digitize the boundary in GetMapArea using Lat/Long scaling, the preferred method.  Buggy as it is, this will soon become your map source of choice for drainage areas.  It is just amazing in how far free GIS info has come.
Instead you might try  GoogleKML2Text.exe  to read Google Earth Pro created polygon KML files and convert to text boundary lat-longs for use by LatLongPixelsFromFile.exe
Boundaries and lines are set by mouse clicks.  Saves boundary and stream coodinates to text file and annotated map to jpg or bmp graphic file.  Rainfall durations and runoff methods included.  Help is available on its menu if you're Rational.

Get MapArea quickly compares effects of dimensionless graph selection, lag, loss method, storm arrangement and routing method... and yes, I didnt forget the Rational Method... why I have no idea. ;-)   Tatum's travel time, Muskingum, and Modified Puls routings included for routing and combining hydrographs saved to file.  A triple triangular unit hydrograph method and a linear reservoir method have been added for calibrating rainfall runoff coefficients for GetRealTime.exe.  Reads rainfall data from the GetAccess HDB database or text file.  For an example of a case study you can follow for setting up GetRealtime for automated Nexrad Radar-Runoff computations go here.  For a Youtube Video using Google Maps with GetMapArea go here.  And for more great sources for maps, check out topo's and huc's on Google Earth at the bottome of this page.

Why just be Rational?... try some of this Dimensionalessness!  Video for Getting Started with GetMapArea


5) GetFlowRecord.xls--(updated 10/13/09) An Excel workbook with 15 worksheets for computing, documenting, and storing stream flow records using methods of the the US Geological Survery as described in online water supply paper:

Complete system with software to maintain the hydrologic database (HDB) once you have brought your field gage height record back from the stream side data logger.  (I don't have a data logger so I used GetRealtime to download realtime USGS gage heights... I said I was no Dr. Fontane. ;-) )

Overview of the GetFlowRecord process:
1) Create rating. Sheet4.Measurements.
2) Enter shifts to apply. Sheet4.Measurements.
3) Load field GH's to HDB. Sheet0.LoadHDB.
4) Enter GH corrections. Sheet6.GageCorrections.
5) Retrieve field GH's from HDB and apply corrections. Sheet6.GageCorrections.
6) Run primary computations on GH's. Sheet7.PrimaryComps.
7) Write final GH and Flow to HDB. Sheet6.GageCorrections.
8) Document, document, document...


6) GetNexrad 4.1.3

GetNexrad.exe is a tool used to view NOAA WSR-88D Nexrad doppler radar images and compute point and area average rainfall and to generate the basin point file used by GetRealtime.exe for automating computaion of a basin average rainfall time series in real time. Also NASCAR racing fans can try to out best crew chiefs like Larry McReyonlds about how near the rain is to the race track. GetNexrad will compute the ETA of rain cells arriving (and leaving) at the race track. 


Traditional area average rainfall is obtained by rainfall gages located in or near the area of interest and averaging the rain gage amounts using many methods.  If you’re lucky you might find a rain gage nearby or you would have to install and maintain a network of rain gages yourself,  The tools presented here will allow you to create point rainfall rates ANYWHERE in the US and greatly improve area averaged amounts and best of all IT’S FREE!!!


The National Oceanic and Atmospheric Administration (NOAA) is a fantastic government agency responsible for the majority of the weather data and alerts in the United States. Using the publicly available and easily accessible reflectivity data from one of the WSR-88D class radar systems (NEXRAD), the tools presented here will show you how to choose a location and set up virtual rainfall collection for a precise geographical area.  Please note that this is not a substitute for severe weather alerts issued by the NWS, but GetNexrad will even sound an alarm when alerts are issued.


NOAA’s explanation of the WSR-88D radar system. (http://www.roc.noaa.gov/)


Software Requirements—GetMapArea is a must for creating the basin boundary except for point locations. Optionally for automating real time collection, storage, and display of the basin rainfall requires GetRealtime. These softwares are available online for free at GetNexradHelp .


Image acquisition:


The WSR-88D class radar systems have many acquisition modes for developing precipitation. The most commonly used form of radar energy return mapping are the Base and Composite Reflectivity maps, and also the 1-Hour Total Precipitation.  The 1-Hour Total image has had additional processing to better correlate with actual rainfall for different seasons and areas, but don't believe it.  We can use any of these three images for the processing of localized precipitation information.


To begin finding radars, fire up your Windows Internet Explorer and go here to http://radar.weather.gov/


Click on the Las Vegas NV ESX radar point on the USA map Enhanced Version tab. 

GetNexrad will take the information in the NOAA N0R or NCR radar image and convert it to the one below where basin area average rainfall rate and point rainfall rate can be displayed.  (rate >> inches for retrieval time step... knuckle head<<<me).

The N1P 1-Hour Total is treated also as a rate of  inches/hour in 5-minutes.

After playing with GetNexrad, I hope you will take the next step in setting up GetRealtime to automate retrieval, storage, and display of your basin of interest’s rainfall amounts and learn how to compute runoff and route it.  GetMapArea is an easy and fun way to get started computing runoff.

7) VolumeTimer.exe--(updated 9/16/09)
Tired of those annoying commercials when listening to online radio on your PC??? Well, just set the times for turning down the commercial volume and then back up automatically. For you talk show enthusiasts just think of it... No more moronic public service ads from the nanny state at tax payer expense or top of the hour mainstream news propoganda. Nervana!!!

If this Volumetimer.exe does not work for you try VolumeTimer2.exe.
8) CookingTimer.exe--(updated 4/8/10)
Need a simple timer alarm for use while on your PC and trying to cook a turkey too?  Well, here you go:

CookingTimer video tutorial at softoxi.com
***** Well don't that beat all.  Pull your hair out trying to get hydrological data when all people want is an easier way to cook their turkey!*****  
9) ChannelStorage.exe--(updated 12/1/2013)
Creates a trapezoid channel's depth-flow-storage rating file used by GetMapArea.exe, GetGraphs.exe, and now GetRealtime.exe for their Modified Puls routing method.  Includes optimized cascades.

(Note: ChannelStorage and ModPulXsec use Manning's normal depth.

ModPulXsec.exe should give the same results as Hec-1 or Hec-Ras given a steady flow value in cfs at 1 cross-section with a main channel and left and right bank over flow channels all the same length (sum of the 3 conveyances).

ModPulXsec does not do multi-xsection energy accounting, just plain old normal depth. I found it to give the same results for modified puls routings for a single average x-sextion as a rating doing 20 x-sections in Hec-Ras. It depends on if you just want to route a flow or if you actually want to look at elevations at 20 x-sections up and down the reach..

ChannelStorage.exe is even simpler where a trapazoidle channel is given with normal depth..

If you have culverts and ponding and loop ratings with channel slope less than 10 ft/mile, GetRealtime can shell Hec-Ras unsteady flow projects and read the results back into GetRealtime.

Don't over engineer this if you just want to route a hydrograph from A to B. Put your effort in getting good rainfall if you want to over engineer something.)

10) ModPulXsec.exee--(updated 7/20/2014)
Creates a channel ModPuls rating depth-flow-storage rating file used by GetMapArea.exe, GetGraphs.exe, GetRealtime.exe for their Modified Puls routing method.  .  Includes optimal number of cascading reservoirs.  Also computes Mukingum-Cunge K & X and it's cascades.

11) Modpuls.xls--(updated 5/24/10)
Route flood runoff hydrograph inflows in your Excel Workdbook using the Modified Puls channel and level pool method.  Modified Puls has always produced the best channel routings for me. (probably because I never could get the hang of the guess work using the Muskingam method correctly.)

12) HurricaneAlex2010Gifss--
NEXRAD Gif image files of Hurricane Alex as it came ashore June 30, 2010.  Use GetNexrad.exe to view images as loops.  Includes Brownsville, Texas KBOR radar gifs for N0R, N1P, NTP, NET, N0V, N0S... etc. every 5 minutes for viewing as 1-hour loops.  See HurricaneAlexReadMe.txt included for more info.  The NTP storm total rainfall even as it just started to come ashore is amazing... to a desert rat.

14 Topo Maps on Google Earth
--Here’s a slick little trick indeed! This is the best map tip since gas stations handed out free road maps. Experiment with the transparency to get the best of both worlds or just the topo world. (For those like me that can't find the 'Places' menu it is under 'View' > 'Sidebar'.) Great for use with GetMapArea.exe above.  And also don't forget to check out HUC boundaries and streamlines on Google Earth here (try the rastor first).  Or the amazing  USGS map viewer with Content, Hydrography and Contours.  I remember when I had to walk 5 miles to school up hill both ways and back home for lunch... these kids today... and their music is just noise.  ;-)

15 ExampleXLrangeToGif.xls--Excel VBA code example to convert your Excel data table or range to a Gif picture file and automatically send it to your Web Host directory.  The GIF image greatly reduces the complexity of maintaining data tables on your web pages.
16 Oklahoma Tornado Level 2 Images--May 20, 2013 Oklahoma  Level 2 debri ball sequence I downloaded with the NWS Weather Toolkit for display by GetNexrad.  Always install GetNexrad in a separate directory for Toolkit images as opossed to real-time images to keep overlays seperated.
