Catch our presentations below at the 2019 TFMA Fall Summit.

Title: Hands-on HEC-RAS 2D Workshop
When: 8 a.m. to 5 p.m. Tuesday, Aug. 27
Presenters: Garrett Johnston, PE, CFM
Holly Ahumada, PE, CFM
What: This hands-on workshop will provide an overview of the new capabilities of HEC-RAS 5. For over two decades, the US Army Corps of Engineers’ free HEC-RAS software has been the industry-leading standard for hydraulic river modeling and channel design. Version 5, released in 2016, is a major update that allows engineers to model twodimensional surface flow.

Title: Professional Ethics for Engineers
When: 4:30-5 p.m. Wednesday, Aug. 28
Presenters: Alan Greer, PE
Gina Smith, SPHR-SCP, CPM
What: During this session, participants will view and discuss videos of tragedies that occurred because of failed ethical decisions. Participants will apply the NSPE Code of Ethics to case studies published by the Board of Ethical Review (BER). 

Title: Lessons Learned from a Benefit-Cost Analysis of Dam Ownership
When: 4-4:30 p.m. Wednesday, Aug. 28
Presenters: Kenneth Lynn Schaub, CPESC (Fort Hood)
Maggie Puckett, EIT
What: This presentation will summarize the use of unsteady-state 1-D US Army Corps HEC-River Analysis System (RAS) hydraulic modeling to evaluate combinations of dam alternatives and these associated impacts to floodplains for eight annual exceedance probability flood events (50%, 20%, 10%, 4%, 2%, 1%, 0.4%, 0.2%) along the studied river systems. 

Title: Upland Avenue – ICPR4 Comparison of 1D/2D Modeling Results
When: 4-4:30 p.m. Thursday, Aug. 29
Presenter: Adam Nixon, PE (City of Lubbock)
Heather Keister, PE, CFM
Bethany Fleitman, EIT, CFM
What: This presentation will explain why  Interconnected Channel and Pond Routing 4 (ICPR4) was used to perform a drainage analysis along Upland Avenue  as well as present the modeling software benefits in this specific case through presentation of a comparison of 1D and 2D results.

Title: The 411 on 404: How to Navigate Your Project Through the Clean Water Act
When: 2-2:30 p.m. Thursday, Aug. 29
Presenters: Michael Lane
Dan Gise
What: This presentation will cover an  overview of some of the issues that may trigger the need for a 404 permit, some of the more common general (nationwide) permits (and their components) associated with small water resource projects, when a permittee does not have to notify the USACE, and how to address some of the challenges that clients may face when utilizing these permits. Additionally, this presentation will highlight the importance of why permittees need to document when USACE notification is NOT required to authorize their project(s).

Title: Hurricane Harvey Recovery: Modernizing Drainage Systems Inside a Fully Developed Levee
When: 10-11 a.m. Friday, Aug. 30
Presenters: Phil Martin, CFM (Fort Bend County Levee Improvement District No. 2)
Hector Olmos, PE, CFM
Ron Cass, PE, PMP (AECOM)
Craig Kalkomey, PE, CFM (LJA Engineering)
What: The Fort Bend County Levee Improvement District No. 2 is two years into a four-year, $75,000,000 CIP to modernize the 40-year old drainage system, as quickly as possible, using the latest standards and best available data. During Harvey, LID 2 and the City of Sugar Land engaged Freese and Nichols to model the internal drainage system and identify the causes of, and potential solutions to, structural flooding. Initial results were presented to the public within 2 months. As modeling continued, LID 2 adopted modern design standards for all flood control projects, including higher freeboard requirements and ATLAS 14 rainfall.
