FUNDAMENTALS OF CFD MODELING FOR WEIR AND SPILLWAY STRUCTURES GETTING A HANDLE ON COMMUNICATING RISKS AND BENEFITS OF DAMS

Registration Fee $200 Registration Fee $300

Details This half-day introductory computational fluid dynamics (CFD) workshop is designed for engineers interested in learning the fundamentals of CFD modeling for weir and spillway structures. The first part covers the essential materials needed to create a complete CFD model, with a focus on understanding the factors that drive model accuracy (in particular meshing and numerical settings). This knowledge is then applied to worked examples for a range of structures, from ogee spillways to more complex configurations such as stepped spillways, siphons, and gated structures, as well as Piano Key weirs and Labyrinth weirs. Throughout the session, we reference high-performance computing implementations commonly used for large-scale and high-accuracy modeling.

This workshop is delivered in a lecture-like, “follow along” format, with video tutorials of the model setup for all the examples to be downloaded by anyone interested in running the models themselves. To this end, all attendees will be given a 3-month license to a commonly used CFD modeling tool (FLOW-3D HYDRO) in order to further consolidate gains beyond the workshop. Details Raising awareness of dams, including their benefits and risks, helps upstream and downstream emergency and flood risk managers and the public take actions to reduce the impacts of floods and prepare for emergencies. Having a plan to share relevant and actionable information is key. This session will walk participants through how to develop a communication plan and use it to guide actions to raise awareness and share information about dams with upstream and downstream audiences. This full day training session, delivered by the U.S. Army Corps of Engineers, will provide participants tools to get started on their communication plans for their dams.
