Bringing Flood Modeling to Life Through HEC-RAS 2D Training

Freese and Nichols works closely with public agencies and communities to help them make informed decisions using flood modeling that reflects real-world conditions. As two-dimensional hydraulic modeling becomes more widely used, clients increasingly seek guidance not only on how to build HEC-RAS 2D models, but also how to review them, interpret results, and understand their limitations.
To support that need, Freese and Nichols hosted a series of HEC-RAS 2D training sessions in Oklahoma and Arkansas. The half-day courses brought together more than 40 participants for hands-on instruction led by the firm’s hydrologic and hydraulic modeling professionals.
The sessions combined technical instruction with practical application, drawing on Freese and Nichols’ experience delivering flood studies, infrastructure designs and regulatory support for clients throughout the region. Participants explored when simpler, one-dimensional models are sufficient and when more detailed two-dimensional modeling is needed to better understand flood behavior. The training covered how to build a 2D model using available data, how to create and refine a computational mesh that runs efficiently and produces reliable results and how to account for bridges, culverts, and other structures that influence water movement. Instructors also guided participants through reviewing model results to confirm they reasonably reflect real-world conditions.
A strong emphasis was placed on model review and quality control, drawing on best practices Freese and Nichols uses to help clients reduce rework, manage risk, and gain confidence in model outcomes. Instructors shared practical approaches that can be applied to active projects, including:
- Aligning model review efforts with the purpose of the study
- Reviewing small areas early to identify issues before they grow
- Breaking reviews into manageable milestones
- Establishing a stable model foundation before adding complexity
- Testing draft deliverables early in the process
- Confirming model features are working as intended
- Understanding and clearly communicating model limitations
By pairing technical instruction with practical guidance, the training provided participants with tools they can apply directly to flood risk management, infrastructure planning, and regulatory decision-making. Freese and Nichols regularly partners with clients to apply these practices on real projects and offers customized HEC-RAS 2D training tailored to specific study goals and regulatory requirements.
