Conclusions The successful damming of the Dnepr near Kanev by the bermless method with the use of small- and medium-grained sands shows
that this method can find widespread use in the future when constructing hydraulic structures on lowland rivers. In addition
to the good organization of the operations, the success of damming can be attributed to the high discharge capacity of the
tailrace and its convenient linking with the river channel being dammed.

Conclusion During construction of the Sayano-Shushenskoe hydrostation ice was passed through the narrowed 130-m wide channel for 7 years
and for 3 years through the 5.3-m wide dewatering outlets which, during the ice run, were not submerged and operated as narrow
deep bays with wide separating piers. Observations established that the planned and actual outer and height contours of the
earth cofferdams and cribs of the foundation area of the first stage and their construction successfully performed their functions
under rather complex ice conditions (especially in the springs of 1969–1971).
For the first time in hydrotechnical construction practice conparatively large ice runs were passed through 5.3-m ice-discharge
bays. The appropriate hydraulic conditions (flow depth more than 9–10 m and approach velocities more than 3 m/sec) were the
decisive factors providing for the successful passage of ice under these conditions.
Consideration of the experience by previously constructed Siberian hydrostations on rivers with heavy ice runs made it possible
to make simple and economic decisions with respect to individual problems (rejection of high jackets on the cribs, use of
earth cofferdams, use of narrow first stage dewatering outlets). In the future when using schemes for ice passages through
narrow dewatering outlets under more rigorous climatic conditions it is necessary to take into account the possibility of
their considerable freezing over and intensified ice formation in them during the winter.
The solution to complex problems of ice passage when constructing hydrostations on the middle and lower reaches of large Siberian
rivers requires further on-site observations at hydrostations under construction and improvement of model-calculation methods
of investigation.

1. | When constructing earth dams the inclusion of foreign members in the form of reinforced-concrete galleries, shafts, etc., in the body of the structure is impermissible. It is also desirable to eliminate the construction of a grouting gallery under the dam. The foundation should be grouted either before or after constructing the dam. |
2. | Installation of monitoring and measuring equipment for observations during operation must be done after completing construction of the dam. Installation of MME during construction leads to its complete disturbance, holds up the rate of filling, and affects the quality of the works. |
