Conclusions

  1. 1.

    Experience during three years with the use of a self-propelled ice-cutting machine to break up ice covers to prevent ice-jam formation and to improve the ice-passing conditions indicated the technical and economic expediency of this type of work.

  2. 2.

    More preferable for the conditions considered in this article is an ice-cutting scheme designed to cut the ice cover by three longitudinal and transverse cuts at mean spacings of 150–200 m.

  3. 3.

    The beginning and end of the work must be established by taking into account the ice thickness and strength, the variations of the ambient temperature, the capacity and weight of the machine, and the work volume.

  4. 4.

    Preventive ice-cutting work has an optimum effect when combined with fluctuations of the water level in the reservoir.

  5. 5.

    It is necessary to carry out further investigations in order to improve the construction of ice-cutting machines to make possible their wider utilization to prevent ice-jam formation in river and reservoir and to facilitate the passage of ice through hydraulic structures.
