Temperature analysis for minor regulative reservoir in winter

Generally design some minor regulative reservoirs at long-distance water transfer project. As it located in interior of land ,water in the reservoir will be frozen for the influence of abominable climate in the winter. Temperature analysis for water in reservoir are done according to the Shentongzhui Reservoir of Wanjiazhai Yin Huang Ru Jin Project .Calculating results show that① Keep the high water level of reservoir as far as possible. ② If temperature of water is no more than 1.5 ℃s at intake of Wanjiazhai hinge , increase discharge quantity to avoid water frozen.
