Technical presentations from the 2024 World Environmental & Water Resources Congress:

Automated Meshing and 3D Visualizations for 2D Bridges and Culverts in SMS/SRH-2D (20 minutes)

This presentation explores the advancements in two-dimensional hydraulic modeling with SRH2D, focusing on automated meshing for bridges and culverts. The historical evolution from manual mesh development to near-complete automation is highlighted, including the transition from the FESWIMS model to the finite volume model. Key features such as unstructured meshes, multiple boundary conditions, and the modeling of hydraulic structures are discussed. The presentation also covers the integration of advanced meshing techniques for bridges and culverts, improving the precision and efficiency of hydraulic engineering practices.

Application of Computational Fluid Dynamics Modeling to Study Maximum Allowable Gate Openings at Spillways (15 minutes)

This presentation discusses the application of computational fluid dynamics (CFD) to determine the maximum allowable gate openings (MAGO) at spillways. This involves optimizing spillway designs to prevent downstream scour and ensure safe operation under various flow conditions. The study incorporates both static parameters, like structure geometry, and dynamic parameters, such as stage levels and gate operations. Results from CFD simulations are used to optimize the geometric location of new spillways and validate MAGO curves for existing structures.

Drainage Area Limitations of Single Watershed, Peak Flow Estimates from NRCS Methods(22 minutes)

This presentation examines the limitations of single watershed peak flow estimates using NRCS methods. It addresses the accuracy of these estimates across different drainage areas and explores potential improvements. The presentation involves analyzing various scenarios to determine how well the NRCS methods perform in predicting peak flows. Findings suggest that refinements in the methods could lead to better predictions and more reliable watershed management practices.
