RESPEC releases the beta version of HSPEXP+1.40. This release comes with a capability to conduct multiple simulations if the parameter values are provided in a separate specification file. This capability can be used for sensitivity analysis, Monte Carlo simulations, Generalized Likelihood Uncertainty Estimation (GLUE), testing scenarios etc.

Please go through the warnings and the usage instructions before downloading and using this capability. Feel free to use Github's issue tracker if you have any issues. Do mention the software and the version number in the subject line.

Thanks and happy modeling.

Warnings:

  1. This is a beta version, and it may not work on your computer.
  2. The results have not been tested thoroughly, and it is advised that the users check their result independently.
  3. This option has not been tested for cases where the number of simulations is in the thousands; we are not sure how HSPEXP+ will behave in those cases.
  4. Since this is a beta version, all intermediate UCI files are saved; users are advised to check if the correct parameters were changed.
  5. HSPEXP+1.40beta may not be able to change all the parameters and may give undecipherable errors.
  6. HSPEXP+1.40beta may not be able to change the parameters by land use and operation numbers.
  7. HSPEXP+1.40beta does not actively show a counter of the number of simulations complete.
  8. All the features offered in this version may change, and may not be available in the officially released versions.

Usage:

  1. When a user selects the option for Sensitivity/Uncertainty Analysis for the first time with an HSPF model, HSPEXP+1.40beta generates a sensitivity specification file.
  2. The sensitivity specification file is a comma separated (*.csv) file with the list of DSNs that are analyzed during each simulation, and the list of parameters that are varied for each simulation.
  3. The default sensitivity specification file contains the first three WDM DSNs from the EXT TARGETS block for output analysis.
  4. The default sensitivity specification file contains LZSN and INFILT as the parameters for analysis.
  5. HSPEXP+1.40 beta also copies the DSN in a new WDM file for each simulation for later analysis.
