Abstract Submission: The use of 2D hydraulic modeling has become the state of practice for the hydraulic design of transportation structures and many other applications, yet many users are not aware of many tools and best practices that are available to improve model development time, reduce simulation time, and improve the accuracy of results. The FHWA Resource Center has been providing technical support for 2D modeling to state Departments of Transportation (DOTs) for more than 20 years and strives to aid in improving efficiency and results. Numerous best practices have been identified through experience in working with DOTs, new feature development, and comparison of different 2D models. The importance of these best practices will be demonstrated through multiple case study examples of models involving detailed hydraulic analyses of bridges and culverts. Examples of how these best practices apply to bridge scour analyses will also be shared.
