Download Links

  • New! Wall Gage Creator — This companion program allows users to create flow-graduated staff gages for any hydraulic structure for which a rating table or rating equation is known. Gages produced are similar to those generated by WinFlume.

USBRWeir Release Notes

  • The 2007 version throws "compiler errors" when it loads, but should work once you have acknowledged the errors.
  • The 2010 version requires the user to manually print the rating curve chart. For unknown reasons, Excel crashes when the rating curve is printed from inside of a macro, so I have hidden the "Print Rating Curve" button..
