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

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 water around a bridge removes sediment… Read More »

River Hydraulics in Steep Canyon Environments

This is a view of US 34 within the Big Thompson Canyon during the final repair phase in late 2017. By John Hunt, PE; Will deRosset, PE, CFM; and Anthony Alvarado, PE, CFM The September 2013 flood in Colorado devastated the northern Front Range, causing widespread damage to critical infrastructure and transportation networks. Hundreds of… Read More »
