What is Computational Fluid Dynamics/3D Hydraulic Modeling?

By Matthew Hickox, PE Computational fluid dynamics (CFD), also known as three-dimensional (3D) hydraulic modeling, is a practical way to predict and visualize how water flows in real-world conditions – including in rivers, stormwater structures, and wastewater systems. CFD solves fundamental flow equations that describe how physical laws govern fluid motion. It also provides detail… Read More »

Battling Bridge Scour with Research, Inspections, and Training

By Brian Schroeder, PE, CBI, CWI Some of the most important foundational elements of a bridge are its least visible – the abutments, piers, piles, and footings submerged under the waterline. That’s where bridge inspectors look for scour – the erosion of soil surrounding a bridge foundation (piers and abutments). Bridge scour occurs when fast-moving… Read More »
