activity, fault displacement estimates, development of seismic parameters for ground motion

estimates, and review of seismic slope stability analyses.

Upper Feather River Dams Safety Review Board

California State Department of Water Resources | Northern California

Current member of Dam Safety Review Board responsible for assessing performance and

conditions of 3 dams in northeastern California. Work involves field inspections, review of design

SIGNIFICANT RESEARCH PROJECTS:

Risk assessment for landslides — pre and post failure deformations of landslides and constructed slopes. This project was sponsored by the ARC and organisations in Australia, New Zealand, Canada and the USA.

Internal Erosion and Piping Failure of Dams. These projects were responsible for investigations of the mechanics of concentrated leak erosion, suffusion, and filters which are too coarse to satisfy no-erosion filter criteria based on extensive laboratory testing. These investigations and review of case study data were used to progressively develop event tree methods for estimating the probability of failure of dams by internal erosion and piping. As part of these studies the Hole Erosion Test to assess the erodibility of soils was developed. These projects were sponsored by the ARC and dam organisations in Australia, New Zealand, Canada, USA and Sweden.

Cracking of Embankment Dams, and the Implications for Internal Erosion and Piping Failure. This uses laboratory testing and numerical analysis to develop methods for predicting cracking in dams, and the swelling/erosion in the cracks leading to internal erosion and piping. The project is sponsored by the ARC and dam organisations in Australia, Sweden and the USA. This project was completed in 2005.

Erosion of Embankment Dams and Dam Spillways. This project has three components:

Erosion of unlined spillways in rock based on laboratory hydraulics tests and case data; Backward erosion piping and global backward erosion / suffusion of embankment dams

and their foundations,

Numerical modelling of cracking of embankment dams and the implications for internal erosion and piping.

This project is sponsored by the ARC and dam organisations in Australia and Sweden. It has recently been completed. It is planned to update the method for estimating the probability of failure of dams and their foundations based on these investigations and published information. That is due for completion in 2018.

of the power penstock upstream of the powerplant; the construction of a new gated

auxiliary spillway on the right abutment of the dam; the addition of concrete overlays

on the concrete gravity wing dams and concrete thrust blocks; the addition of internal

drains within the dam and in the dam foundation; and the installation of post-

tensioned anchors in the arch portion of the dam and though the left thrust block. The

work initiated during the appraisal design phase and continued through feasibility

designs, final designs and then through two construction contracts. As team leader,

he reviewed design drawings and calculations, made presentations to the Consultant

Review Board, was lead author of design summary, served as Technical Proposal

Evaluation Committee (TPEC) member, participated in foundation approvals and

helped resolve issues that developed during construction.

McPhee Dam Spillway Modification, Dolores, CO Lead Designer for spillway modification which involved adding a ramp and air intakes

to mitigate the potential for cavitation damage in the spillway chute. The work

involved working closely with the Hydraulics Laboratory to incorporate physical model

study results into a refined design and coordinating a specification package for the

work.

Best Practices for Dam and Levee Safety Risk Analysis Served as one of the original developers of a risk analysis training class focusing on

best practices for analyzing various potential failure modes and estimating risks.

Developed the original presentations for the following potential failure modes - flood

overtopping of dams, spillway chute wall overtopping, stagnation pressures in

spillway and outlet works chutes, cavitation damage in spillway chutes, seismic and

normal operating condition failure of radial gates and spillway erosion. Has been a

consistent presenter at Best Practices training classes for Reclamation and the

United States Army Corps of Engineers as well as other federal agencies and

consulting engineers.

Dam Safety Risk Analysis Facilitator, Bureau of Reclamation, Denver, CO. Served as risk analysis facilitator and peer reviewer for multi-day team risk analysis

efforts including Issue Evaluations, Corrective Action Studies and Risk Reduction

studies. Responsible for planning the session, coordinating with project managers

and subject matter experts, and leading the team through development of potential

failure modes, expert elicitation of risk estimates, and life loss estimates. Also served

as risk analysis facilitator for numerous one day team risk analyses that addressed a

case histories, analysis tools, potential failure modes and risks for both embankment

and concrete dams. Served as instructor for dam safety risk analysis topics as part of

Reclamation’s domestic and international Safety Evaluation of Existing Dams (SEED)

seminars. In addition, helped organize and made presentations related to the

analysis and evaluation of concrete dams and developing potential failure modes and

estimating risks for concrete dams as part of USSD and ICOLD workshops.

Senior Dam Engineer, Comprehensive Facility Reviews, Bureau of Reclamation, Denver, CO. Served as Senior Dam Engineer on comprehensive dam safety reviews and was responsible for coordinating the entire report and had lead responsibilities

for the evaluation of design, analysis and construction section, the potential failure

modes section, the consequence section, the risk analysis section and the technical

report of findings section of the report. Served this role on the following Reclamation

dams: Seminoe Dam, WY (295 ft. concrete arch), Kortes Dam, WY (244 ft. concrete

gravity), Pathfinder Dam, WY (214 ft. cyclopean masonry gravity arch), Angostura,

SD (193 ft. composite with concrete gravity and embankment wing dam sections),

Project Experience

Dam Safety Program Management, U.S. Army Corps of Engineers (USACE) – Los Angeles District, Los Angeles, CA. Dam Safety Program Manager. Mr. Goldstein managed the District Dam Safety Program, which ensures the safety and operational adequacy of 17 federally constructed dams within the southwestern United States through continuous risk assessment, risk management, and risk communication. With management abilities in the areas of design, construction, operation, maintenance, inspection, and evaluation of dams, he was responsible for overall dam safety project execution, training of project personnel, upward reporting and vertical coordination, instrumentation program, and interfacing with federal/non-federal partners and stakeholders. He also used technical engineering expertise to provide support in reviewing dam safety recommendations in analytical reports to provide risk-informed prioritization of needed repairs and further engineering analyses. Mr. Goldstein partnered with County and other local municipalities on communicating flood risks associated with dams and developed risk-informed solutions. He conducted daily activities for the District Dam Safety Program, including budget development, schedule monitoring, technical oversight, vertical team briefings, and coordination of the review of all dam safety reports. He worked with other program and budget managers to ensure that dam safety requirements are included and properly prioritized in the District Operations and Main
