CHINCOLD

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 annual precipitation in 2022 was 631.5 mm. The total water consumption in 2022 was 599.8 km3, of which the agriculture water consumption was 378.1 km3, industry water consumption was 96.8 km3 and domestic water consumption was 90.6 km3. Per capita domestic water consumption averages 425 m3/year.

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 2021 totalled 8543.25 TWh, of which 5805.87 TWh (70.0 per cent) was generated by fossil fuel thermal power, 1339.00 TWh (15.7 per cent) by hydropower, 407.52 TWh (4.8 per cent) by nuclear, and 990.86 TWh (11.6 per cent) by wind and solar power.

Total electricity consumption in 2021 increased to 8313 TWh, of which secondary industry (manufacturing) accounted for 67.5 per cent, tertiary industry (services) for 16.1 per cent, households for 17.1 per cent and primary industry for 1.2 per cent. Per capita electricity consumption was 5813 kWh. By 2050, it is expected 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.

China has a small hydro (less than 10 MW) potential equivalent to about 128 GW. Total small hydro capacity up to 2021 stood at 81.34 GW, with an annual output of 242.4 TWh, accounting for just more than 50 per cent of the world’s total small hydro capacity.

Symposium Program

Spanish National Committee on Large Dams (SPANCOLD), Japan Commission on Large Dams (JCOLD), French Committee on Large Dams (CFBR) and Chinese National Committee on Large Dams (CHINCOLD) have the honor to invite professionals to the 9th International Symposium on Roller Compacted Concrete (RCC) Dams and Cemented Material Dams, which will be held in Dec.4th-8th,2023 in Guangzhou City, China.

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.

Cemented Material Dam (CMD) is a new type of dams, which includes Hardfill dam, Cemented Sand and Gravel dam (CSG), Cemented Sand, Gravel and Rock dam (CSGR), Rock-filled Concrete dam (RCD), Cemented Soil dam (CSD), and so on. There are more than 200 CMD projects constructed and under construction.

The 9th International Symposium on Roller Compacted Concrete (RCC) Dams and Cemented Material Dams will provide a platform 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 and CMDs. Beside international best practice, the participants will also have the occasion to visit some famous RCC dams and CMDs in China in operation or under construction.
