I have blogged about this before. My neighbor, Paul Medved, got his civil engineering degree from the UC Davis. As noted on Wikipedia, "the Hydrologic Engineering Center (HEC) in Davis, California developed the River Analysis System (RAS) to aid hydraulic engineers in channel flow analysis and floodplain determination. It includes numerous data entry capabilities, hydraulic analysis components, data storage and management capabilities, and graphing and reporting capabilities." HEC-RAS is used to model the hydraulics of water flow through natural rivers and other channels.
A while back, the AEC team developed a river analysis extension for AutoCAD Civil 3D and AutoCAD Map 3D. You can download it from the Autodesk Labs site:
River Analysis Extension for AutoCAD Civil 3D / AutoCAD Map 3D
This technology preview supports HEC-RAS within the AutoCAD Civil 3D 2012 and AutoCAD Map 3D 2012 environments. It allows you to compute water surface profiles for modeling bridges, culverts, spillways, levees, bridge scour, floodway delineation, floodplain reclamation, stream diversions, channel improvements, and split flows.
The original technology preview expired on December 31, 2012. This update extends the technology preview to June 30, 2013. The team created this extension since some users were midstream in their use of the technology, and the team wanted to get their feedback as to how their projects turned out. Existing users should uninstall the old technology preview and install the newly downloaded one.
Motivational speaker, Matt Foley, lives in a van down by the river (video). Now Paul can continue to determine just how close the van can park near the river by using the technology preview to compute cross sections, flood plains, and contours - all while still in AutoCAD Civil 3D or AutoCAD Map 3D. Please give this technology preview a try and let us know what you think. There are a few ways to do so.
Water analysis is once again alive in the lab.
