Floodplain Mapping Using HEC-GeoRAS and RAS Mapper

Date & Time: 
Tue, 03/03/2015 - 12:00pm - 1:00pm
Location: 
S&ME, Inc., 6190 Enterprise Court, Dublin OH 43016

*Open only to Central Ohio Section Members
*Seating is limited to the first 25 people
*Bring your own lunch

Purpose and Background
HEC-GeoRAS is an ArcGIS toolbar that helps to incorporate LiDAR and other topographic datasets in to HEC-RAS. This webinar will demonstrate how to easily add topographic data to a HEC-RAS model once the HEC-RAS model has been run, and how to map the resulting floodplain using both HEC-GeoRAS and the new HEC-RAS tool, RAS Mapper.

RSVP to MMarquis@smeinc.com by Friday, Feb. 27, 2015.

Primary Discussion Topics

  • HEC-GeoRAS files
  • Incorporating survey data
  • Attributing Shapefiles
  • Exporting to HEC-RAS
  • Importing into HEC-RAS
  • Setting up the HEC-RAS geometry file
  • Mapping results in RAS Mapper
  • Exporting results and mapping with HEC-GeoRAS

Learning Outcomes

  • Understand how to create HEC-RAS models based on topographic data that can include survey
  • Know how to map the results using both RAS Mapper and HEC-GeoRAS once the HEC-RAS model is created

Webinar Benefits

  • Learn how to set up a HEC-RAS model based on topographic data
  • Learn out to efficiently incorporate survey data into a HEC-RAS model
  • Learn how to partially or fully replace HEC-RAS cross sections based on topographic data
  • Understand differences between mapping results with RAS Mapper and HEC- GeoRAS

Intended Audience
Engineering professionals interested in creating, or modifying HEC-RAS models, or mapping floodplains. One should have a basic knowledge of ArcGIS and HEC-RAS to attend this webinar.

The Central Ohio Section of ASCE sponsors free continuing education webinars as a service to our members. These webinars are produced by ASCE and normally cost $250 or $300 for ASCE members. However, the Central Ohio Section is paying the registration fee and inviting any interested section members to attend for free. Just RSVP by the deadline. Seating is limited, so do not delay.

You can see the complete list of webinars available from ASCE National on their website. If you see one you like, let us know. If you and your company would like to host one, let us know that too. If you open it up to any interested Central Ohio ASCE section members to come, we will pay the registration fee.
