Programs

Please note: All files except the map, pdl, par and climate normal files are now in GreenKenue format.

CHARMx is configured for execution speed. There is no checking on array bounds and other possible problems. If there is a program crash with out an error message, the debug version should be run.   

CHARMd is configured for debugging. This should be run if the speed version crashed as it provides more information and internal checking (e.g. array bounds).  A crash is a crash if the program does not provide the user with a diagnostic message.  Please send NK a screen dump of the error message for a diagnosis of the problem. You may have to send the files causing the problem as well.

These new versions MAY need a new wfo.spec.txt  file automatically created by bsn.exe. You will be so informed when you run the program.

May 10/17 - From Nov. 2016 Version 10.1.49 until Version 10.1.83 evaporation was not taken out of river channels after the lake evaporation model was revised. This has been corrected with 10.1.83

Apr. 6/17 - A problem with frame labelling for leap years in the watflood.wfo file has been fixed. This resulted in the plot labelling being off by 1 day.

- The outfies.txt files has been revised: changed order of files and added unit numbers.

- DLL's no longer needed.

Dec. 21/16 - A bug in the Manning's n reduction for multiple streams in one grid was inactive and has been (re)activated. This may affect hydrograph timing in upstream sub-watersheds. To get the same results as with previous versions, set chnl(1-5)=1.0 in the par file.

Oct. 30/16 - New flags for ice factor for rivers & lakes.

Aug. 3/16 - Added observed flows to the watflood.wfo file. Requires new wfo_spec.txt file.

Added results\lakename.tb0 output file. Requires tb0flg = 'y' in the event file. Default = 'n'

Aug. 31/15 - Reservoir Target Levels added. Contact NK.

May 04/15 - Fixed a problem with the resume file: heat deficit not reset for a resume on Jan. 1.

Mar. 06/15 - Fixed channel depth calculation in wetland routing. This bug was initiated Jan. 15/15 when the wetland routing was revised. It affected timing only - slowing wetland outflow.

Feb. 13/15 Fixed  levels.txt & resin.csv to match values in the lake_sd.csv file. Previously data was not properly extracted from the model because of miss-matched timing.

Feb. 04/15 update: Fill missing (-1.0) initial reservoir releases with first +ve values encountered.

NEW Jan. 13/14

A number of enhancements are being implemented at this time but have not been extensively tested. The additions include a lake evaporation model being developed at the University of Manitoba by Prof. Trish Stadnyk; an updated Hargreaves ET algorithm; the use of a variable latitude based on the grid latidude as opposed to a central watershed latitude; and the addition of the daily difference of temperatures for each grid on a daily basis as opposed to the use of the current monthly_climate_normals for the whole domain.  To use the new model, new event files will be required to incorporate the new files.

Updated Apr. 07/14 - with this update, in the par file set the flgevp2 = 2.0 for the old method and flgevp2 = 4.0 to use daily temperature differences and Hargreaves & Samani 1985. TMP64x.exe will generate the yyyymmdd_dif.r2c  files.

Dynamically Dimensioned Search - DDS

 DDS with pre-emption is available here DDS_p.zip    and dds_wfld_rev5.zip  

(Last updated Aug. 28, 2018)

NEW   Lapse rates for precipitation and temperature, as well as radius of influence, damping coefficient and a ratio for interception capacity can now be included in optimization.

The csv format par files are required.

For background information on DDS please see  http://www.civil.uwaterloo.ca/btolson/papers.htm 

Parameter file update:

Please switch from the old par file format to the new par.csv format ASP. The old format will not be supported in future revisions. A new format par.csv file is automatically created every time splx?? is run if an old format file is used. Simple rename the new_par.csv in the basin directory to the proper name and enter this name in the event file.

With the new par.csv file, the bsnm.sdc file is now incorporated in the par file and is no longer used. However, a new file monthly_climate_normals.txt file is now required in the basin directory. This file is also automatically created.

The new format par.csv files should be edited in EXCEL^TM  This setup is a great improvement over the old formats. They are easier to edit and understand. But be careful: there are no diagnostics in the read program just yet. However, if you do have a problem, run the debug program and you will see how far you got along in reading the file.  Please see Section 4.1 in the manual for an example par file.

moist.exe reads the soil moisture point data file (yyyymmdd_psm.tb0)and creates the soil moisture gridded data file (.gsm)  (Last updated Apr. 1,2018) 

For 32bit version:  moist32.zip  (Last updated Aug. 28, 2018)  

Ragmet.exe reads point precipitation (yyyymmdd_rag.tb0) files containing point rainfalls and distributes the point rainfall to the grid specified in the bsnm.pdl (point data location) file. The gridded precipitation has the _met.r2c extension.  This program now will do the sequence of events in the event file in one single run and allows for a radius of influence and smoothing at precip stations - see manual.  RAGMET.exe no longer reads the ragmet.par file but instead reads the bsnm_par.csv file. You can optimize the lapse rate, radius of influence & smoothing distance with dds. Debug version   ragmet64d.zip    See manual.

(Last updated Aug. 28, 2018)  (Fixed leap year time stamps)

For 32 bit version:   ragmet32x.zip  ragmet32d.zip Last updated June 5/16

This program reads point temperature (yyyymmdd_tag.tb0 ) files and distributes the temperatures to the grid specified in the bsnm.pdl (point data location) file. It must use the same grid as the gridded precipitation file (_met.r2c). The gridded temperature has the _tem.r2c extension. TMP.exe no longer reads the ragmet.par file but instead reads the bsnm_par.csv file. For debug mode  tmp64d.zip   (Last updated Aug. 28, 2018)  (Fixed leap year time stamps)
