Hydrotechnical Construction Aims and scope

Conclusions

  1. 1.

    Adopting the proposed method of computation, having reliable initial data which is characteristic of the water-ice flow and of the condition of its interaction with the structure, it is possible to compute the passage of ice over the crest of an incomplete dam.

  2. 2.

    The minimum allowable span width of the crest for the condition of unobstructed movement of ice through the hydrocomplex is given by Eq. (13).

  3. 3.

    For passing all ice arriving from upstream, a width of span b>(1.2–1.4)bmin is necessary.
