GENERAL SESSIONS Monday, September 11 8:30 am - 9:30 am Welcome and ASDSO Annual Report Jonathon Garton, P.E., ASDSO President Oroville Incident: What was (Not) Learned from St. Francis Dam Failure. St. Francis Dam, owned by the City of Los Angeles, was a 205-foot tall concrete arched gravity dam. On March 12, 1928 just before midnight, the dam failed catastrophically. The resulting flood wave rampaged for over 5 hours as it traveled 54 miles downstream from the dam to the Pacific Ocean. It destroyed thousands of acres of farmland, ripped apart more than a thousand structures, and cut short more than 400 lives. Now, 90 years later, very few who witnessed

design and construction; and dismissal of warning signs, which included excessive concrete cracking, seepage through the abutments and foundation, and ground movement at the east abutment. The recent spillway failure incident at Oroville Dam suggests that some of the lessons from the St. Francis Dam failure had not been adequately understood even decades after the failure. Common factors include, misunderstanding of the site geology, lack of humility of individuals involved design and construction, insufficient review of designs, missing warning signs, and insufficient dissemination of state-of-practice technical knowledge within the dam engineering profession. In both cases, the problem was not lack of sufficient knowledge collectively within the industry, but rather insufficient awareness and application of that knowledge; this “root cause” remains to be remedied in the dam engineering profession.

Tuesday, September 12 8:30 am - 10:00 am Discussion of Lessons to be Learned from the 2017 Oroville Dam Spillway Incident

the flood remain alive, but review of first-hand accounts collected over the years reminds us of how truly horrific it was. The design and construction were supervised by the famous William Mulholland, a man credited with quenching Los Angeles’ thirst for water as the city rapidly grew. Many considered this self-taught man from Ireland one of the greatest civil engineers of the time. So how could this dam fail so catastrophically, just 12 hours after Mulholland himself had inspected it and deemed it to be safe? Numerous physical factors contributed to the failure including: instability and slaking, susceptibility of the dam foundations and abutments, insufficient base width, raising the height of the dam twice during construction, and lack of provisions to account for uplift pressures. But the mechanics of how the dam failed are only part of the story. “Human factors” which interacted with the physical factors included inadequate geologic exploration and understanding; overconfidence in Mulholland’s expertise, inadequate experience of Mulholland’s design team; lack of Professional Engineer registration requirements in California; excessive cost and schedule pressures; an exemption in California state law which resulted in lack of outside review of the DamSafety.org/DS18

The report of the independent forensic investigation of the Oroville Dam spillway incident of February 2017 included several lessons to be learned for the dam safety industry. This soap box session will include a discussion of several of those lessons. The session will be moderated by John France, the team leader for the forensic investigation, and will feature a panel of key figures with first-hand knowledge of the Oroville Dam incident, as well as dam safety regulators and dam owners from other parts of the U.S. The format of this interactive discussion will focus on specific lessons identified by the forensic team, additional viewpoints from the panel, and questions from the audience.

SPECIALTY WORKSHOPS On-Site Response Guidance for Seepage and Internal Erosion Incidents

Dam-Break Flood Modeling/Mapping Using DSSWISE Lite

When: Thursday, Sept. 13, 8:30 am – 12:00 pm. Coffee and registration/check-in from 8:00 am – 8:30 am.

When: Thursday, September 13 - 8:30 am - 5:30 pm. Coffee and registration/check-in from 8:00 am – 8:30 am.

Responding to uncontrolled seepage that has initiated internal erosion of an embankment or foundation can be especially challenging. The conditions leading to mechanisms of seepage and internal erosion of earthen dams are reasonably well understood by experts who specialize in these topics. Ongoing research and experience with actual dam incidents are further increasing and refining that understanding. However, a missing link appears to be how to translate that knowledge into specific guidance for real-world emergency response during an uncontrolled seepage and internal erosion event.

DSS-WISE™ Lite is a web-based, automated two-dimensional dam and levee-break flood modeling and mapping capability developed at the National Center for Computational Hydroscience and Engineering at, the University of Mississippi. The DSS-WISE™ Web platform provides access to a secure, web-based graphical user interface and a map server. DSS-WISE™ Lite is used by federal agencies and state dam safety offices for dam safety studies and preparing emergency action plans. Because if its exceptional speed, it has also been used for operational modeling and emergency response planning efforts.

This one-half day workshop has two main objectives: 1) provide concise, step-by-step guidance for key technical elements of response to the seepage/internal erosion event; and 2) practice implementing this guidance by conducting team table-top response exercises.

This one-day short-course will cover: • the system components for DSS-WISE™ Web and GUI; • dam-break flood hydraulics and the computational engine; • how to set up and run “reservoir-type” and “hydrographtype” simulations; • how to view and use the results files provided; • population databases and explains estimation of consequences of flood on populations; • automated input data preparation; and • typical user mistakes and how to avoid them.

The workshop will address: • selecting practical, potentially available materials for rapid construction of filters and drains, including aggregates and geosynthetic materials applicable to the range of flow rates encountered; • typical designs of practical filters and drains, including zoning/layering and their dimensions; and • practical, proven methods of construction under conditions of active seepage flow. Additional details on the workshop agenda, instructors and handouts is available at DamSafety.org/DS18On-Site. Professional Development Hours: Up to 3.5 professional development hours are available for attending the full workshop. Attendees will receive a form on which to record contact hours for continuing education credits. Registration Information: $200 per person includes all course materials as well as beverage breaks.

This short course is designed for practicing engineers and emergency managers, federal and state agencies, and consulting companies with an interest in dam safety and dam-break flood modeling. It does not require any prior experience in numerical modeling, but a general understanding of the concepts of dam safety would be helpful. Participants should bring their own laptop to use in the group exercise session. The laptop should be Wi-Fi enabled and have a web browser (other than Internet Explorer). Participants should also have a GIS software (such as ArcGIS or QGIS) and a spreadsheet software (such as Microsoft Excel) installed on their laptop. Additional details on the workshop agenda, software recommendations, instructors and handouts is available at DamSafety.org/DS18DSSWISE. Professional Development Hours: Up to 8 professional development hours are available for attending the full workshop. Attendees will receive a form on which to record contact hours for continuing education credits. Registration Information: $300 per person includes all course materials as well as beverage breaks.

FIELD TRIPS Mud Mountain Dam

Masonry Dam and Cedar River Watershed

When: Thursday, September 13, 8:00 am â&#x20AC;&#x201C; 4:15 pm

When: Thursday, September 13, 12:00 pm â&#x20AC;&#x201C; 6:00 pm

Mud Mountain Dam is a critical flood risk management project of the United States Army Corps of Engineers, Seattle District. Completed in 1948, after the establishment of the 1936 Flood Risk Management Act, it is a 432 foot tall earth embankment dam in a narrow canyon on the White River on the boundary between King and Pierce Counties in Washington State.

The Cedar River Watershed and Masonry Dam are located 35 miles southeast of Seattle. The 90,638-acre watershed supports a diverse ecosystem and provides about 70% of the drinking water to 1.4 million people in the greater Seattle area. From the Cedar River Watershed, melting snow and rain drain to the Chester Morse Lake and the Masonry Pool reservoirs created by the Masonry Dam. Listed in order from upstream to downstream, the project facilities consist of an RCC dam (Overflow Dike), a 210 foot high cyclopean concrete gravity dam (Masonry Dam), and a power tunnel and penstocks for transport of water to the powerhouse located approximately 2 river miles downstream of the Masonry Dam. The RCC dam, (overflow dike) splits the reservoir at lower water elevations between Chester Morse Lake and the Masonry Pool. This dam helps minimize water losses from the Masonry Pool due to seepage through the glacial moraine forming the right abutment during times when water storage is more important.

The embankment itself is a rock-fill dam with a concrete cutoff wall in an earth core with a crest elevation of 1,257 feet. The width at the base of the embankment is 1600 feet which tapers off to 25 feet at the crest. The 1,200 long spillway has a capacity of moving 245,000 cubic feet of water per second and is designed as an uncontrolled chute to protect the dam in the event a flood risks overtopping the embankment. The intake and tunnel structures include a 9-foot sediment bypass tunnel and 23-foot fish and flood flow passage tunnel. The tunnels are design to pass normal river flows through the project (averaging 1,429 cubic feet per second) to include any sediment bed load and downstream fish passage as juvenile fish migrate to the Puget Sound.

Registration Information: $95 per person includes motorcoach transportation, guided facility tours, box lunch and beverages.

While only used for flood management, the project reservoir area stretches 5.5 miles upstream of the dam and is capable of storing 106,000 acre-feet or 34.5 billion gallons of water. The project provides essential flood risk management to many commercial, and residential neighborhoods throughout the southern Puget Sound region, as well as critical industries such as lumber and wood processing, aircraft production, tech industry (including critical Amazon server farms), heavy warehousing, agriculture, and port facilities in Tacoma. The total population protected by the dam is approximately 278,000 and includes the cities of Buckley, Enumclaw, Sumner, Puyallup, and Tacoma. The project also includes year-round day-use recreational facilities to include play structures, picnic shelters, two viewing decks, the only wading pool in the USACE inventory, and miles of trails throughout the land surrounding the reservoir. Registration Information: $95 per person includes motorcoach transportation, guided facility tours, box lunch and beverages.

SOAPBOX SESSION Wednesday, September 12 Toward Industry-Wide Use of Best Technical Practices Overview: It is foundational to the sound practice of engineering that practitioners use the best available technical guidance.

Representatives from the following industry sectors will provide perspectives on this issue: • State dam safety regulator • Consulting firms • Private dam owner • Federal dam owner/regulator The second part of the session is to ask the audience questions about potential solutions. The remaining time will be spent examining strategies for implementation of these solutions. Session Facilitator: Mark E. Baker, P.E., Dam & Levee Safety Officer, National Park Service

Yahoola Creek Dam, Dahlonega, GA

Research shows that best practices available at the time were not used in the design of many dams that later experienced major incidents and failures (examples: Anita, Teton, Fontenelle, Big Bay, Silver Lake, and Oroville). The recent Oroville Forensic Investigation Report states: “[An] issue specific to the dam engineering and safety industry is that the available technical literature is not organized as a set of unified and integrated national guidelines which are regularly updated. Instead, the technical literature in the United States related to dams, while very extensive, is scattered across several federal agencies, most of the states, and professional organizations such as ASDSO and USSD. Engineers assigned to address the safety of dams and their appurtenances must not only be familiar with these dam safety organizations, but must also keep up with the current state of practice in dam engineering. This can be a significant task for an engineer who is only occasionally assigned to work on dams and spillways.”

Industry-wide use of best practices also has the potential to highlight needed research, reduce problems in construction, and decrease the need for later dam modifications. Many other industries have developed common technical guidelines/standards, including the bridge and transportation industry. This soapbox is to ascertain the extent of this problem and to explore how we can increase the use of best technical practices throughout our dam safety community. After an introduction, we will share results of a survey on the issue.

NETWORKING One of the most valuable experiences you can have at a conference is networking. While the conference schedule can make it hard to find time to meet new people, ASDSO has built in numerous opportunities for you to expand your professional network and meet new dam and levee safety professionals. Aside from the technical sessions, workshops, and field trips below are a few of the many opportunities provided by Dam Safety 2018.

Dine Around

Exhibit Hall

Young Professionals Networking Opportunities

The networking hub of the conference, the exhibit hall offers a plethora of opportunities to network with fellow attendees.

The newly formed ASDSO Young Professionals Interest Group will host a number of networking and social events as part of the Dam Safety 2018 conference. In addition, the Young Professional Interest Group will have its own tables as a part of the dine around and will hold an open meeting during the conference. Watch for more details on all events at DamSafety.org/YP or visit today and sign up for the YP email list.

The annual conference dine around will take place on Tuesday, September 11. Past attendees have told us that participating in the dine around is the perfect place to meet new people from across the country (and the world) and share experiences in a casual environment. Watch DamSafety.org/DS18 for more details.

Student Networking Opportunities

Receptions and Special Events Two evening receptions will be held in the exhibit hall, Monday, September 10 and Tuesday, September 11. Enjoy appetizers and network with over 100 exhibitors where you have the opportunity to learn about the latest, and greatest products and services available. In addition to the receptions, lunch is provided in the exhibit hall on Wednesday, September 12, and breakfast and breaks are held in the exhibit hall on Tuesday, September 11 and Wednesday, September 12.

Educational Outreach committee members will host informal info/Q&A sessions in the Resource Center during conference hours for class groups by appointment.
