STRUCTURES

DEC has built a firm foundation in dam and hydraulic structures services and design. From feasibility and design to inspection and construction management, DEC is a trusted civil engineering source for dam knowledge and experience.

SELECTED PROJECTS

RODGERS DAM

The historical dam failed on the Humboldt River due to its sandy foundation. DEC completed the full design and associated engineering for the reconstruction of the dam. This project won the NWRA Major Project of the Year - Rural (Civil).

 The dual 48" steel penstocks on the Rye Patch Dam failed. DEC was called in to perform the design, permitting, and construction management for the complex project.  This project won the AGC Pinnicle Award.

RYE-PATCH DAM
PENSTOCKS
ZUNINO DAM & DIKE REHAB.

DEC performed a fall dam rebuild, including 2,400 feet of dikes for the State of Nevada. It also included a 5-acre fish pond and bentonite cutoff trenching. The project was awarded runner up for Project of the Year in 2015 by the Truckee Meadow ASCE.

This dam breach analysis presented a complex problem due to an undefined flow path and an immediately adjacent railroad line. The solution was a 2D hydraulic model with an integrated dam breach simulation as show in the video above. The results produced flow velocities, and water depths at railroad over-topping points.
