stability to withstand the current Maximum Credible Earthquake (MCE), and hydraulic adequacy of the

existing spillway to handle updated Probable Maximum Flood (PMF). Performed an engineering/safety

inspection and investigation of the dam. Cores were obtained to assess the existing condition of the concrete

(including petrographic analysis). Design earthquakes were developed using actual ground motion records

scaled to spectrally match a target spectrum. Linear-elastic and non-linear finite element analyses were

performed to assess the seismic stability of the dam. Updated hydrologic analyses were performed to

develop inflow hydrology for evaluation of the existing spillway. (1999 – Present)

Member Board of Review for annual review and evaluation of monitoring and mitigation programs

conducted by NB Power dealing with severe autogenous growth problems in the concrete of the head works

dam, spillways and powerhouse structures due to AAR (Alkali Aggregate Reactivity). Unprecedented

expansion due to AAR has resulted in NB Power adopting a range of measures to combat the ongoing

expansion including a regular program of saw-cutting monolith blocks in the head works adjacent to the

spillway, between generation bays in the powerhouse, and in spillway access bridge slabs, excising portions

of six penstock encasements and replacement with expansion couplings and a program of continuous

realignment of the turbine and generator shafts to accommodate out-of-round and out-of-plumb ness of the

units due to the AAR expansion. (1998-present)

Boundary Dam, Spillway and Outlet Works Plunge Pool TDG, Washington, U.S.A. Client: Seattle City Light

Mr. Tarbox was a member of a three person Panel of Experts that provided oversight and technical reviews

of a program to study alternative project modifications to reduce the level of total dissolved gases in the

plunge pool and tailrace area of the project. The overall long-term objectives of the field, laboratory and

CFD studies were to identify operational measures and to support low level spillway sluices and upper level

radial gated spillway modifications that could be implemented to improve TDG performance of the energy

dissipating plunge pool. A 1:25 scale physical hydraulic model was constructed and a test program

conceived to develop rating curves for all flow outlets, making velocity measurements in the project tailrace

(for use in CFD model calibration), and characterizing the performance of the existing dam. The physical

model was used to examine; rating curves, trajectory, and throttled flow behavior. Computational fluid

dynamics was applied to develop a detailed examination of the expansion of flow as water exits the sluice

gates as well as examination of the jet as it interacts with the plunge pool. Successful alternatives were

selected for implementation that helped to reduce the TDG issues. (2006-2012)

Project Manager for the risk assessment of a series of dams on the Bear River. The study demonstrated an

Incremental Consequence Assessment (ICA) for the four dams, Soda Point, Grace, Oneida and Cutler. A key

element of the risk assessment included a failure mode analysis for each dam. The results were presented to

the Federal Energy Regulatory Commission (FERC) by the Owner to illustrate the threat posed to

downstream dams by upstream dams in a cascading failure scenario in probabilistic, economic and safety

terms. The Owner’s proposals for upgrading the dams were based on the results of the risk assessment and

were accepted by the FERC. (1988)

Tongue River Dam Risk Assessment, Montana, U.S.A. Client: Montana Department of Natural Resources

Project Manager for conducting a risk assessment of the 91-foot high embankment dam and free overflow

spillway. Responsible for the studies to conduct a failure mode analysis and to evaluate a number of

alternative actions to mitigate the high risk costs of property loss and threat to lives lost The risk assessment

illustrated how a risk-based comparison of several structural and non-structural alternatives can be used to

address spillway inadequacies. The evaluations were presented in probabilistic terms and also as cost-to-

save-a-life for each remedial action alternative. The risk assessment was used by the Owner to continue

operating restrictions, improve the dam break flood warning system and to seek government funding for

upgrading the dam. (1986)

Upper Stillwater Dam, Utah, U.S.A. Client: U.S. Bureau of Reclamation

As Head of the Concrete Dams Section, initiated and directed the studies for developing the concepts,

designs and cost estimates for the Bureau’s first state-of-the-art RCC dam. It is a 310 foot high gravity dam,

2670 feet long and contains 1,400,000 cubic yards of roller compacted concrete located on Rock Creek. It

was the largest RCC dam constructed at the time of its completion. (1978-1981)

Nambe Falls Dam, New Mexico, U.S.A. Client: U.S. Bureau of Reclamation

Supervisory Structural Engineer responsible for the design of the 150-foot high, 320-foot long double

curvature thin arch concrete dam located on the Rio Nambe near Santa Fe. It is a composite dam with a

concrete gravity thrust block for the left abutment of the arch dam designed to replicate the sloping canyon

topography. The thrust block is also the right abutment for a 144-foot high, 670-foot long embankment dam

that ties the composite structure to the high point of the reservoir on the left abutment. A unique scheme was

conceived to pre-stress the arch dam by installing Freysinet flat jacks over the entire surface of the central

contraction joint and then inflating them using a water/glycol mixture to expand the arch upstream against

Page 1



the reservoir. This operation resulted in locking into the arch dam a pattern of stresses at the abutments and

the crown that overcame tensile stresses due to severe winter temperatures that occur at the site. The use of

3D FEM analysis made it possible to analyze the complex combination of concrete structures and the

prestressing effects. (1976-1977)

constructed on the North Fork of the American River. Responsibilities included the development of

computer programs to analyze the reduction of uniaxial and radial jacking test data and in-situ stress

relief testing. Implemented the first applications of two dimensional finite element analysis to

determine the effective deformation modulus of the dam foundation, revised the computer program

ADSAS (Arch Dam

Stress Analysis System) to accommodate elliptical arch geometry and to perform dynamic analysis

for earthquake ground motions. The first application of the three dimensional finite element method

was introduced to analyze the dam for static and dynamic stresses. Mr. Tarbox initiated and helped to

develop a laboratory testing program to determine the rapid strain rate tensile strength and modulus

Page 1



of rupture for mass concrete that demonstrated the reserve strength of mass concrete during earthquake

loading conditions and the increase in modulus of elasticity during dynamic response. This also

marked the first time that comparisons were made for a Bureau of Reclamation designed dam

between the stresses determined by three-dimensional physical laboratory models, ADSAS and 3D
