A description of some of the water and storm modeling tools in Civil 3D. This was a specialized presentation, so the slide background was scrubbed out and a standard design used in its place.

  3. 3. Watersheds of land where all the water Watersheds are the areas that is under it, or drains off of it goes into the same place. They are divided up into basins where all of the water drains to some outlet
  4. 4. Subdividing Basins  All land drains to somewhere  Major basins are further subdivided into smaller basins
  5. 5. Subheadline goes here and here
  6. 6. Modeling  Runoff is determined for a basin  It is determined by o The anticipated rainfall – amount of water in o The imperviousness of the soil – how much gets absorbed o The characteristics of the ground cover – the rate of flow
  7. 7. GIS Overlays
  8. 8. Using your stream data to do calculations and analysis

  10. 10. HEC-RAS The HEC-RAS system contains four one- dimensional river analysis components for: o steady flow water surface profile computations; o unsteady flow simulation o movable boundary sediment transport o water quality analysis.
  11. 11. Autodesk’s Interchange Tool HEC RAS Import/Export Extension for AutoCAD Civil 3D 2010  Available from the Subscription Center  Includes an import tool  Converts Civil 3D objects into HEC-RAS format (.GEO)  Includes an export tool  Converts HEC-RAS GIS output file (.SDF) into Civil 3D objects  Installs into the Toolbox
  12. 12. Process  Create an alignment for the stream flow  Create cross section sample lines o Draw polylines and convert to sample group  Create polylines for the left and right bank  Export data into .GEO file  Open .GEO file in HEC-RAS  Do Calculations and Analysis  Export results to SDF  Import SDF into Civil 3D
