近三十年水文、气象资料表明，头屯河水量的90％由制材厂水文站以上流域汇入，河道泥沙主要来自水库实验站以上中游河段，河道来水量与输沙量变化不完全一致，年径流量的多寡与年降水量密切相关，河流输沙量则与春、夏季节的暴雨或阵发性降水有关。头屯河最大月径流量出现在7月份，而最大月输沙量则出现在6月份，与最大降水月（6月）出现时间一致。汛期河道来水量占全年总数的60－65％，而来沙量占全年总数的80－85％，后者集中度更大，汛期的降水量与强度对河道来水、来沙的日变化影响很大。
Nearly thirty years of hydrological and meteorological data show that 90% of the Toutun River’s water volume flows in from the hydrological station above the hydrological station. The sediment of the river channel mainly comes from the upper reaches of the reservoir experimental station, and the change of water quantity and sediment load in the river channel does not change In full agreement, the amount of annual runoff is closely related to the annual precipitation. The amount of sediment transported by the river is related to rainstorms or paroxysmal precipitation in spring and summer. The maximum monthly runoff of Toutun River occurred in July, while the maximum monthly sediment discharge occurred in June, coinciding with the appearance of the maximum precipitation month (June). In flood season, river water accounts for 60-65% of the total number of the year, while the amount of sediment in the whole year accounts for 80-85% of the total. The latter is more concentrated. The rainfall and intensity in flood season bring water to the river, Changes have a great impact.
