The Utah Water Research Laboratory, within the Civil and Environmental Engineering Department of Utah State University, has often worked with the U.S. Army Corps of Engineers on upgrades to existing Corps dams, spillways, and other facilities. So when the Corps' Sacramento (California) District approached the laboratory in 2014 about a new spillway for the Isabella Lake Dam Safety Modification Project to gready increase the spillways discharge capacity, the laboratory knew just what to give it, says Blake Tullis, Ph.D., F.EWRI, the associate vice president for research at Utah State and a professor of civil and environmental engineering. "We said we have this paper on arced labyrinth weirs that you might want to consider," explains Tullis. The paper, "Arced Labyrinth Weirs" by B. M. Crookston, Ph.D., PE., MASCE, and Tullis (Journal of Hydraulic Engineering, Vol. 138, Issue 6 (June 2012)), was based on applied research the water lab had conducted a few years prior to the Corps' request. After reviewing the research, the Corps felt that a zigzagging weir could be the right solution for the Lake Isabella dams. |
