Abstract: On the rivers with a long period of ice flow, difficulties in water collecting can occur. The purpose of this paper is working out hydraulic ways of withdrawal strainer protection against frazil and avoiding supercooling effect inside the system. This paper concerns difficulties arising in the operation of river withdrawals situated in the frazil producing river stretches. Methods of calculations of frazil flow parameters are given. The construction of water strainers of umbrella-like type and system of collector well heating on the basis of compositional resistive materials (CRM) ensuring safe operation of withdrawals in frazil-ice conditions are proposed. The results of experimental analysis of the new strainer construction and the parameters of the new heating system of the water collector well are represented.
