Benefits of 2D Modeling for River Hydraulics
By Dusty Robinson, PE Two-dimensional (2D) hydraulic models are not new to the industry; they’ve been in use for close to 30 years. However, older 2D models required highly experienced users and the technology was expensive and cumbersome so they were typically only used on complex projects. Recently, advances in computer technology and 2D modeling… Read More »

Well-designed Sidewalks Keep Pedestrians, Communities on the Move
By Jeffrey Siewert, PE Safe sidewalks are essential. They keep pedestrians connected to their communities for work and recreation, and economies thrive when well-designed sidewalks can keep all that foot traffic moving. Why build sidewalks? Here are a few reasons: Sidewalks help keep pedestrians and motorists separated and safe. The Federal Highway Administration (FHWA) notes… Read More »

An Update – And Some Advice – On the (Delayed) New Datums That Are Coming
By Richard Kleinmann, PLS Now that we’ve crossed over into the year 2022, many members of the geospatial may feel like they’ve just dodged a collective bullet while the rest of us might be thinking, “What bullet is that?” I’m talking about the proverbial “carpet” under your feet shifting a couple of feet both horizontally and vertically in some areas of… Read More »
