Abstract Submission: Two-dimensional (2D) hydraulics models have been widely used in engineering practice for flood simulation, bridge design, habitat restoration, and many other purposes. There is a need for the community to be aware of and follow general best practices for 2D modeling. If a model is not properly developed, contains error or otherwise does not follow best practices, the simulation results may not be accurate or even be wrong. This talk will give a quick introduction to Chapter 5 “Development of 2D Modeling Best Practices” in the NCHRP Research Report 1077 “Selection and Application of Manning’s Roughness Values in Two-Dimensional Hydraulic Models”. The best practices cover the whole modeling workflow from pre-processing to post-processing. It is important for a modeler to have a good understanding of the problem to be solved with a model, the strength and weakness of each model, and most importantly good engineering judgement. Some important aspects of 2D model development will be highlighted and discussed.
