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 »
