CFD Hydraulic Modeling Helps Find Solutions to Dam Flow Problems

By Pete Haug, PE Today’s engineering challenges are complex, especially for dam owners and operators. Flow problems around dams include spillway scour, riprap damaging currents, river debris collecting in the wrong places, and uneven overtopping of training walls. Imbalanced flow entering powerhouse units can create trash rack vibrations, excessive bearing wear, and even air-core vortex… Read More »

BIM Delivers Dividends on Unusual Structure Upgrades

By Pete Haug, PE Building information modeling (BIM) can play a big role in keeping the wheels from coming off an intricate project. We’ll look at a case study of a turbine and powerhouse upgrade project where the goal was to minimize changes to the exterior of a historic 1910 dam. But first, here are… Read More »

FHWA Publishes Reference for 2D Hydraulic Modelers

By Dusty Robinson, PE In recent years the popularity of 2D hydraulic modeling has grown, thanks in part to the fact that newer versions are easier to use and are helping modelers better communicate complex hydraulic concepts of real-world river systems. About the Expert: Dusty Robinson, PE, is a water resources engineer in Ayres’ Fort… Read More »
