It’s Time to Raise the Grade on Our Nation’s Infrastructure
The American Society of Civil Engineers recently released the 2021 Report Card for America’s infrastructure. Much like a school report card, the study outlines the condition of 17 major infrastructure categories – from aviation to wastewater – in A to F letter grade format. Sadly – and to be honest, shockingly – we’re not making… Read More »

Post-wildfire Stabilization Requires Quick Action, Sustained Commitment
Ayres staff examines the burn patterns surrounding Comanche Reservoir in January this year to evaluate potential mitigation. By Colin Barry, PG, CFM In 2020, Colorado experienced its largest wildfire in state history. The Cameron Peak fire started August 13 west of Fort Collins in the Arapahoe and Roosevelt national forests, destroying nearly 209,000 acres before… Read More »

How Computational Fluid Dynamics Modeling Solved Aging Dam Dilemma
By Matthew Hickox, PE When complex issues at dams arise due to rapid change or unforeseen deterioration, industry standard design equations and methodologies developed in the 20th century cannot always provide the correct solution. Fortunately, engineers are increasingly able to turn to computational fluid dynamics (CFD) models to confirm the hydraulics situation so that appropriate… Read More »
