渭河是黄河的最大支流,其多年平 均年径流量为80.6亿m3,多年平均输沙 量为3-86亿t。渭河下游(咸阳铁路桥至 入黄口)全长208km,其中咸阳铁路桥 至耿镇桥间37km河段属游荡性河道,河 宽1.2-1.5km,比降6.5(?);耿镇桥至 赤水河间63km河段属过渡性河道,河宽 1.0-3.0km,比降5(?)1.4(?);赤水河 以下108km河段属弯曲性河道,河宽2- 3.3km,比降1.4(?)-0.7“(?)。
The Weihe River, the largest tributary of the Yellow River, has a mean annual runoff of 8.06 billion m3 for many years and an average of 3-86 billion tons of sediment for many years. The lower reaches of the Weihe River (from Xianyang Railway Bridge to Huangkou) are 208km long, of which the 37km stretch between Xianyang Railway Bridge and Gengzhen Bridge is a wandering river with a width of 1.2-1.5km and a ratio of 6.5 (?); Gengzhen Bridge The 63km section of Chishui River is a transitional river with a width of 1.0-3.0km and a specific slope of 5 (?) 1.4 (?). The 108km section below the Chishui River is a bendable channel with a river width of 2- 3.3km and a specific gravity of 1.4 (?) - 0.7 ”(?).
