Intro to the Application of 2D Hydraulic Modeling for Dam and Levee Safety: On-Demand
Recent improvements in the computational capacity of computers and in the availability of high-quality terrain data have allowed 2D hydraulic models to become highly valuable tools in dam and levee safety analyses. Today, there are several free and commercially-available 2D models on the market. This webinar will provide a background on 2D hydraulic modeling theory, identify steps to set up a 2D model, describe important specifications for 2D models, and summarize features available in 2D models. Applications of 2D models for dam and levee safety will be highlighted.
After participating in the webinar, attendees should be able to:
Understand the differences between 1D and 2D models,
Be aware of key features and specifications of 2D models,
Identify situations in which 2D models may be beneficial,
Understand the process involved in setting up a 2D model
Understand the differences between the most well-known 2D models
