Return from SSA

In the last post on Pipe Network Part Matching, we discussed what happens to the STM parts as they enter into the world of Autodesk Storm and Sanitary Sewer.  For now let us say we completed the design and the analysis.  Ultimately, we don’t want to hand the technician the reams of paper that was generated or take the dialog boxes and manually mark up plan sheet in Red Sharpie.  Pens are cheap, but come on!

We want to preserve that precious time and data and seamlessly import that analysis back into AutoCAD Civil 3d.

Pipe Network Part Matching

Kevin Clark did a post earlier this year on “When a Pipe Network Structure isn’t a Pipe Network Structure”.  Autodesk Storm and Sanitary Analysis (SSA) uses the STM file format as the mechanism for exporting a Civil 3d pipe networks out for consumption with SSA and the return trip back into Civil 3d – these settings within the command setting become critical.   Kevin’s focus was on Civil 3d 2010 and what it did during the export to Hydraflow Storm Sewer.   Let us take it one step farther – Autodesk Storm and Sanitary Analysis.

Engineering 101: Manning’s Formula

Someone once said that the study of Hydrology and Hydraulics is one part art, the rest part voodoo.   Hydraulics is so much more an empirical study or relationship than pure voodoo.  I am glad I am not the only one out on a rainy day watching the water rise in the streams, channels and in the backyard sandbox.

This being a week before the great Irish celebration and the week of the IAFSM annual conference, I will dedicate this post to Manning.  No, not Eli or Peyton, but Robert Manning, the District Engineer Engineer of the Arterial Drainage Division of the Irish Office of Public Works.   Sounds like a roadtrip is in order to origins of formula…

Engineering 101: The FAA Equation – Time of Concentration

Let us continue the Engineering 101 series of blog entries.  Over the past few months, we have seen few posts on some basic engineering tasks associated with the engineering study of hydrology.  I would like to make this a recurring series.  If you have any topics that you would like to be covered before, during or after the next set of Civil 3d 2010 topic,  comment away.

Let’s recap the series so far…

Engineering 101: Precipitation

A few months ago, I posted about the Rainfall Intensity and some of the information you will need to generate an intensity-duration-frequency curve.  I want to provide a little more rainfall data, including some links to precipitation data.
