Ethiopia has begun generating electricity at its new 5,000-MW roller-compacted concrete gravity-type dam on the Nile River. The first 375 MW went to the national grid on Feb. 20.
The historic Derby Dam diverts water into the Truckee River that would otherwise flow into Pyramid Lake. However, that diversion led to the near extinction of the endangered native Lahontan cutthroat trout in the lake.
To remediate seismic safety issues and enhance flood-handling capacity at the concrete thin-arch dam, the $32-million project called for cutting a notch in the existing structure, placing a new ogee-shaped spillway and installing reinforced armor at the dam’s base.
While the Federal Emergency Management Agency (FEMA) approved $205 million in federal funds to reimburse California for costs to reconstruct the Oroville Dam spillways damaged by 2017 flooding, it declined to pay the remaining $306 million that the state’s Dept. of Water Resources (DWR) had requested.
When Texas A&M had the chance to snag a “superstar” to join an academic team for the first national study of urban flooding scope and consequences, it knew just who to ask: Gerry Galloway.
