HydroCAD^® Stormwater Modeling - Since 1986

  HydroCAD-10 update
To check your version and read about update options, select Check for Update on the HydroCAD Help menu.

We strongly recommend that everyone run the tutorial that is offered when you start HydroCAD.  You can also run the tutorial by selecting Tutorial on the HydroCAD Help menu.  The tutorial is loaded with important tips and techniques you'll use all the time.  Most of the HydroCAD Owner's Manual is also included in the built-in help system, and answers to most questions can be found by clicking the "Help" button on the related form.  You will also find a PDF version of the Owner's Manual on your software download page or in the CD Reference Library.  We also offer printed copies of the manual.
