The USACE Hydrologic Engineering Center has released a new update of the HEC-RAS version 5.0 beta which includes: spatially varying Manning’s n values for 2D Flow Areas; velocity plotting for 1D and 2D areas; and improved hydraulic structure connections for 2D Flow Areas. The RAS2D computational engine was developed by Ben Chacon at RMA for HEC.

September 29th thru October 1st, 2014 — Fort Worth, TX
John DeGeorge and Mark Ackerman provided a two-day workshop on the new features of the USACE Corps Water Management System – Control and Visualization Interface (CWMS-CAVI) version 3.0. Attendees included staff from the Galveston, Fort Worth, Little Rock, and Tulsa District offices. This training workshop was set up to facilitate the national deployment of the CWMS system for real-time water control operations.

RMA welcomes Caleb DeChant to the team. Caleb comes to RMA with a strong academic and practical background in civil engineering, hydrologic and hydraulic modeling, and computer programming. He received his Ph.D. in civil engineering from Portland State University in June 2014.
