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 »

Bike Lanes, Intersection Improvements Can Change Urban Barrier into Friendlier Corridor
While heavy traffic is part of living in the big city, communities need not sit idly by as their arterial streets become unnecessarily clogged by outdated technology – or begin to feel like dangerous canyons that pedestrians and bicyclists fear to even attempt crossing. Traffic engineers hold the key to streets where shared use by… Read More »

Task Force Positions Geospatial Community for Proposed 2022 Datum Changes
By Dick Kleinmann, PLS The National Geodetic Survey (NGS) soon will be replacing the North American Datum (NAD) of 1983 and the North American Vertical Datum (NAVD) of 1988 to improve the National Spatial Reference System (NSRS) – the system that defines latitude, longitude, height, and orientation throughout the nation.
