IN THE SOVIET NATIONAL COMMITTEE ON LARGE DAMS

THE TENTH INTERNATIONAL CONGRESS

I. L. Sapir and V. M. Semenkov

The Tenth Congress of the International Commission on Large Dams (ICOLD) was held in Montreal, Canada, June 1-5, 1970. The technical and execut ive commit tees held their meetings between May 28 and 30, 1970. About 1000 delegates from 43 member nations of the International Commission on Large Dams were present. From the Soviet Union a delegat ion consisting of the following members part ic ipated in the proceedings of the congress and the technical commit tees: I. L. Sapir (Leader of the Delegation), V. V. Stol 'nikov, A. A. Sorokin, V. M. Semenkov, I. A. Ter-Arakelyan, and G. L. Ignatyuk. The fol!owing questions were discussed:

Question 36, "Recent Developments in the Design and Construction of Earth and Rockfill dams" (50 papers).

Question 37, "S ta te -o f - the -Ar t in the Design and Construction of Dams and Reservoirs on Deep AlIuvinm, Karstie, and Other Unfavorable Formations" (60 papers).

Question 38, "Observations on Dams and Reservoirs in Operation" (61 papers).

Question 39, "Latest Developments in the Design and Construction of Concrete Dams" (33 papers).

Special at tention was devoted to field observations and to controll ing and measuring instruments. In most

countries, where hydrotechnical construction has reached a developed stage, special agencies have been created for making control observations on the condit ion of high dams. The measuring equipment and the observation procedures are developed with great care.

At the plenery sessions of the Congress, the Chief Engineer of Giprovndkhoz, G. L. Ignatyuk, and Prof. V. V. Stol 'nikov presented reports from the Soviet Union. A col lec t ion of papers presented by the Soviet National Com- mi t tee on large dams was distributed and evoked considerable interest among the delegates.

On June 6 and 7, 1970, the Soviet de lega t ion paid a visi t to the site of the Churchill Fails dam. The exper i - ence in construction of a hydroelectr ic station of 11 units generating a total of 5500 MW and built under the severe north Canadian c l ima t e is of great general interest in connection with the construction of hydroelectr ic s ta - tions in the northern regions of the Soviet Union.

The executive commi t tee of the ICOLD also reviewed organizat ional problems and adopted the following resolutions:

1) Mr. Jose Toran (Spain) was e lec ted President for the period 1970-73.

2) Mr. Schwitten (Switzerland) and Mr. lohnson (USA) were e lec ted vice presidents for the same period.

3) Iran and Iraq were admit ted as members.

4) The 39th execut ive commit tee meet ing will be held at Dubrovnik (Yugoslavia) in October, 1971.

5) The 40th execut ive commi t tee meet ing will be held at Canberra (Australia) in 1972.

6) The 41st executive commit tee meet ing will be held in Madrid in 1973.

7)The Eleventh Congress of the International Commission on Large Dams will also be 'he ld in Madrid in 1973.

In the next few issues of "Gidrotekhnicheskoe Stroi tel ' s tvo," we propose to publish abstracts of papers on each question of the Congress and articles on the construction of the Churchill Fails hydroelectr ic station.
