China applied to join the International Committee on Large Dams in December 1973; the application was officially accepted in the 42nd Executive Conference held in Athens in April, 1974. Since then, China has become a member of the ICOLD. The Chinese National Committee on Large Dams is the channel of international activity for Chinese engineers in the field of dam technology; it participates in activities of the ICOLD on behalf of China, aims to carry out academic exchange and cooperation through the Chinese experts in ICOLD, and promotes the development of dam technology and civil engineering technology.

Water Storage and Hydropower Development for China

Water resources

The Ministry of Water Resources is in charge of water resources, and there are seven Water Resources Commissions for the Yangtze, Yellow, Pearl, Huaihe, Haihe and Songliao rivers and Taihu Lake Bureau,as well as Provincial Water Resources Bureaux.

The average annual precipitation is 641.3 mm. The total mean precipitation volume is 6085 km.

China has developed 37 percent of its total water resources (reservoir storage as a percentage of total river water resources). This will be increased to about 50 percent by 2050, so that reservoirs can store more flood water and help resist serious droughts.

There are more than 6500 large dams in operation or under construction that are 30 m or higher.

Power sector

The National Energy Administration is in charge of the power sector. The State Grid Corporation and the Southern Grid Corporation are in charge of construction and operation of the power network. The Ministry of Water Resources is in charge of the development of small hydropower stations.

Electricity production in 2017 totalled 6495 TWh,71.8 percent of which was generated by thermal power. Hydropower accounted for 18.3 per cent of output. Nuclear accounted for3.8 percent, and wind power for 4.8 percent. Total electricity consumption in 2017 was 6307.7 TWh, of which secondary industry (manufacturing) accounted for 70.4 per cent, tertiary industry (services) for 14 per cent, households for 13.8 percent and primary industry for 1.8 percent. Per capita electricity consumption in 2016 was about 4041 kWh. By 2050, it is expect-ed to reach 7300 kWh, equivalent to moderately developed countries.

Hydropower development

China has a theoretical hydropower potential of about 6083 TWh/year. The technically feasible hydro potential is about 2474 TWh/year(541.6 GW).The economically feasible potential is 1753 TWh/year. The technically feasible potential in China accounts for 17 per cent of the world's total. So far, more than 45 per cent of this has been developed.

Large hydropower plants that were fully commissioned in2017-18 include Changheba (2600 MW), comprising four 650 MW units. The first three units were commissioned as of July 2017 with the final 650 MW unit entering into commercial service in December 2017.

Symposium Program

Chinese National Committee on Large Dams (CHINCOLD) and Spanish National Committee on Large Dams (SPANCOLD) have the honor to invite professionals to the 8th International Symposium on Roller Compacted Concrete (RCC) Dams, which will be held on Nov. 11th-12th, 2019 in Kunming City, China, together with the CHINCOLD 2019 Annual Meeting.

RCC dams have the virtues of saving a great deal of concrete, building quickly, making project cost down and early bringing into playing project advantages and so on. Hence, the technique of constructing dams has been quickly spread and applied since it came out. Today there are more than 400 RCC dams in more than 40 countries. Great successful experiences and advanced technologies have been achieved. CHINCOLD and SPANCOLD have devoted to promote the technology from early 1990’s. The first Symposium on RCC dams was jointly organized by the two committees in 1991 in Beijing China, which was a success start of the series of RCC Symposiums.

Following those successful and fruitful Symposiums held in Beijing (China) in 1991, Santander (Spain) in 1995, Chengdu (China) in 1999, Madrid (Spain) in 2003, Zaragoza (Spain) in 2012 and Chengdu (China) in 2015, the coming one jointly organized by CHINCOLD and SPANCOLD, will continue to contribute significantly to the knowledge and application of RCC technology with a wide range of contents and international scope. The Symposium will serve as a perfect venue for practitioners, engineers, researchers, scientists, managers and decision makers from all over the world to exchange ideas and technology about the latest developments dealing with RCC dams.

Beside international best practice, the participants will also have the occasion to visit some famous RCC dams in China in operation or under construction, such as Huangdeng RCC Gravity Dam (H=203m), Jin’anqiao RCC Gravity Dam (H=160m), Dachaoshan RCC Gravity Dam (H=115m), Dahuaqiao RCC Gravity Dam (H=107m) and etc. Also a technical exhibition for enterprises related to hydropower and dams will be held during the Symposium.
