Members of the International Commission on Large Dams (ICOLD) will convene in Bali, Indonesia, June 2-6, 2014, for the organization's 82nd Annual Meeting, where the focus is "Dams in Global Environmental Challenges."

In addition to the annual assembly of ICOLD members, the event includes a one-day symposium on Monday, June 4, where experts will present their research in a number of important areas. The 25 ICOLD technical committees will also meet to compile and share knowledge gained in dam design, construction, maintenance and operation. The annual meeting is also offering technical tours for delegates to take in and around Bali. The exhibition portion of the event will feature companies from all over the globe promoting their products and technologies. Social events are scheduled for delegates to build new relationships while enjoying local cuisine and culture.

Symposium

This year's symposium will focus on the role and impact of dams in global environmental challenges.

The symposium is organized to give as many opportunities to present papers as possible. Experts will be asked to present the latest development in their fields of expertise and to give their views on key issues raised.

The presentations will cover seven broad topics within this focus, all of which speak to the importance of critical infrastructure in regards to environmental management and protection:

- Social and environmental aspects of dams, such as the effects of greenhouse gases, public participation, and land acquisition and resettlement;

- Engineering issues in dam development, including management of and instrumentation for aging dams, dam safety, and natural dams;

- Challenges in tailing dam projects;

- Water quality management, including assessment of sedimentation in the reservoir, bio- geochemical balance disturbances, and modeling;

- Catchment area management for sustainable development, including land use planning, sediment control, public participation, and assessment of catchment erosion;

- Challenges in dam safety policy and implementation, monitoring and early warning systems, risk analysis and management, inspection and instrument monitoring; and

- Dam operation in connection with climate change, including adaption and mitigation of climate change; the role dams play in food, energy, and water security; flood and drought analysis; and revitalization of existing dams and reservoirs.

Papers will be presented orally by authors or displayed as posters in the lobby.

Technical committee workshops

Two technical committee workshops are organized on June 2, where the committees will start their work and then submit bulletins at the general assembly for approval.

State-of-the-art workshops

Each technical committee will first meet in a workshop setting. All members of the technical committees make short presentations that summarize their personal contributions to the technical committee as experts in their countries and based on their professional experiences. These workshops are open to all participants. The discussions give valuable input for the future work of the technical committees.

Final knowledge transfer workshops

At the end of the preparation of the bulletin, each technical committee organizes a workshop where the bulletin is presented by several members. These workshops are open to all participants. The ensuing discussion will give feedback on the bulletins before their submission for approval at the general assembly.

One of the technical tours will visit Telaga Tunjung Dam, an earth fill dam constructed in 2003 that plays a role in irrigation for the surrounding area.

Technical tours

Two all-day technical tours are offered as part of a delegate registration on Thursday, June 5.

The first will travel to Pura Taman Ayun (Temple of Beautiful Garden), a royal temple built in 1634 and designated as one of UNESCOs Cultural World Heritage sites. Next, the group will tour Telaga Tunjung Tabanan Dam, an earthfill dam responsible for irrigating 1,800 hectares. The dam was built in 2003 and is 33 m high, 226 m long, with a volume of 1.3 million m3. The final stop on the tour is to Pura Tanah Lot (Temple of Land in the Middle of the Sea), a tiny island formed by gradual erosion of the ocean tides over thousands of years.

The second technical tour will first visit Titab Dam, which irrigates fields covering 17,498.2 acres. The dam is also the site of a 1.5 MW turbine, which helps to power the dam and the surrounding communities. Lovina Beach is the second stop on the tour, followed by a visit to Lake Beratan, the second largest lake in Bali.

In addition to the technical tours, three pre-meeting and four post-meeting tours are also available for delegates and guests to take that extend beyond the borders of Bali and show dams and power plants in various provinces of Indonesia, including Sumatra, Java, Sulawesi, East Nusa Tenggara, and Yogyakarta.

Additional opportunities

There are a number of other opportunities for delegates to learn and share knowledge beyond the symposium and technical committees, including two workshops on Friday, June 6. Both workshops will be held for delegates, one on small dams and the other on soil cemented dams.

The small dams workshop will discuss safety assurance and environmental aspects on small dams, specifically the regulation, safety and development of small dams, retrofitting small dams in order to adapt to climate change and the environment, and public participation in the development and management of small dams.

The soil cemented dam workshop will feature presentations highlighting the experiences associated with the use of cemented soil, the regulations and construction of small soil cemented dams in Indonesia, as well as a presentation on planning, designing and constructing larger dams in China.

Engineers under the age of 35 are invited to participate in the Young Engineer Forum, which will be held Tuesday, June 2, as well as a correlated networking event on June 5.

Finally, regional clubs will be holding activities, meetings and events to provide delegates the opportunity to exchange knowledge and network within the following regions: European, African, American, Asia-Australia and Francophone.

Exhibition

The exhibition portion of the annual meeting will be open June 3-6 and features approximately 100 booths. Product and service providers with expertise in the following areas will be on hand to present their technology and achievements for delegates: water resource management; constructing and operating contractors; dam construction; engineering and consulting firms; electrification benefits; hydroelectric power companies; designing hydroelectric power stations; plants producing special equipment; environment specialist and consultants; companies working in the field of clean water supply; organizations working in the field of irrigation; organizations and committees financing projects; and computer organizations.

Dams in Indonesia

Indonesia currently faces an urgent demand for the development of sustainable water resources and management due to a rapid population increase and environmental concerns, says Djoko Kirmanto, minister of public works for Indonesia. The development of critical infrastructure is an important component of the country's plan moving forward.

With a current reservoir capacity of 14.93 billion m3, Indonesia has a low ratio of storage per capita when compared to other Asian countries. Minister Kirmanto stated that the country is planning new infrastructure development to add to its fleet of more than 1,000 dams, 130 of which are large. The country is home to 30 conventional hydroelectric plants and five pumped storage facilities with a combined installed capacity of 9,201 MW.


Basuki Hadimuljono, PhD, is the president of the Indonesian National Committee on Large Dams, which is hosting the International Commission on Large Dams' 2014 annual meeting.
