If you haven’t heard about the new (ish) stormwater extensions for Civil3d, I’d recommend heading over to this page to download them and take a look. While I have not had a chance to run through the extensions’ functionality personally, a recent post over at civil3d.com covers some of the basics of rainfall data and how they relate to the AutoCAD extensions. While it will be primarily review for anyone that has taken a course on Hydrology, it’s a good intro to those who are newer to the field.
Also, keep your eyes open for a future post on these extensions once I’ve taken a better look at them.
