Response of Bed Shear Stress in Open-Channel Flow to a Sudden Change in Bed Roughness (Oct 2024, MPC-24-567)
Muhammad Farrukh Jamil, Francis C. K. Ting, and Monika Kafle

The determination of bed shear stress plays a pivotal role in understanding the fluid dynamics in both natural and engineered channels. The commonly employed logarithmic law provides a mathematical formula to compute the bed shear stress in open-channel flows. However, its applicability in flow through...

Analysis of Compound Channel Flow with Two-Dimensional Models (Oct 2017, MPC-17-336)
Francis C. K. Ting, Ryan J. Larsen, and Ryan P. Rossell

The South Dakota Department of Transportation (SDDOT) currently has a Finite-Element Surface-Water Modeling System for Two-Dimensional Flow (FESWMS-2DH) and Research Management Associates 2 (RMA2) Both programs have the capability to model two-dimensional (2D) flow around structures. The department must...

Insights from Depth-Averaged Numerical Simulation of Flow at Bridge Abutments in Compound Channels (Jul 2011, MPC-11-237)
Reinaldo Morales and Robert Ettema

Two-dimensional, depth-averaged flow models are used to study the distribution of flow around spill-through abutments situated on floodplains in compound channels and rectangular channels (flow on very wide floodplains may be treated as rectangular channels). The study leads to useful insights regarding...
