    As Hydrae mentioned it is a model for Western Washington. It was developed for the Department of Ecology is currently maintained by Clear Creek Solutions. It is a GUI for HSPF with precalibrated variables based on project location. If you developed a HSPF model with the same calibration data...

    Batch Open Save Command File

    cad101, Thanks for your help. The script you provided worked, but I modified the last command for my own preference. I also had to enable Automatically Save Design under the Workspace>Preferences>Operation menu. Thanks again!

    Slotted Gate/Narrow Channel?

    Reply to: RWF7437 Thanks for your reply. There was a rating curve developed for this control structure in the 80's, but the city doesn't think it is valid. I believe the city is hoping that there has been some research with something similar and we can take that equation and apply it to this...
