Just draw a line…
The graphical ability to cut cross sections from contours and manipulate the information is one of GeoHECRAS’ strong points. The software makes our HEC‑RAS bridge replacement modeling work much easier and more efficient.
Up until recently we were using the standard Army Corps of Engineers HEC‑RAS to do our bridge modeling work. Cutting additional cross sections was difficult to do, since we would have to draw a line string in MicroStation in order to retrieve the point data. Then, we needed to extract the station-elevation data, and then copy and paste the data into HEC‑RAS. All of this extra work resulted in not many cross sections created in our models.
Whereas with GeoHECRAS, you can simply just draw a line anywhere on your model and the software will extract the cross section information, assign the bank stations, and update the flow lengths—all in one step. We can easily add additional cross sections wherever they are needed. Quite simply, instead of creating just a handful of cross sections with a lot of work, GeoHECRAS allows us to add as many cross sections as necessary with little effort—making our HEC‑RAS model studies more accurate.
