2D Modeling Provides Simple Route to Erosion/Sedimentation Forecasts

The road to river erosion and sedimentation predictions sometimes takes you through the world of sediment transport modeling. These days 2D hydraulic modeling often provides a simpler, less costly route to robust results. Read More »

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 »

A Proactive Program at Work: Investing in Dam Repairs Averts Crisis

By Chris Goodwin, PE Dams are an integral part of our lives, providing recreational opportunities, power generation, flood control, wildlife habitat, and other important functions. More than 2,100 high-hazard-potential dams are operating in the United States, as reported in the American Society of Civil Engineers’ 2017 Infrastructure Report Card. Their failure could result in the… Read More »
