陕西省交口抽渭灌区取水枢纽设在临潼县交口镇西楼村“S”弯道处,距此上游20多公里处设有船北水文站。目前笔者仅依 1970～1984年14年的流量资料,根据相关分析的有关理论,探讨该灌区冬春季河道来水的预报方法。 一、冬春季渭河来水成因分析 渭河为横贯关中的最大河流,源于甘肃省渭源县,至潼关入黄河,全长672km。流域面积116580km~2,流量补
The water intake hub of the Jiaogui irrigation and drainage system in Shaanxi Province is located at the “S” bend of Xilou Village, Jiaokou Town, Lintong County. From there, there is the North Hydrology Station over 20 kilometers upstream. At present, the author only uses the flow data from 1970 to 1984 for 14 years, and based on the relevant theory, discusses the prediction method of river runoff in winter and spring in this irrigation area. First, the spring and winter Weihe River inflow origin analysis Weihe River is the largest river across the Guanzhong, from Weiyuan County in Gansu Province, to Tongguan into the Yellow River, a total length of 672km. Watershed area of 116580km ~ 2, traffic make up
