补充资料:渭河
渭河 黄河最大支流。位于中国陕西省中部。源出甘肃省渭源县鸟鼠山,东流横贯陕西省渭河平原,于潼关注入黄河。全长818千米,流域面积13.47万平方千米。由于地质构造上的原因,北岸支流源远流长,如葫芦河、千河、泾河、洛河等,这些河流流经黄土高原,洪枯流量相差悬殊,泥沙含量大,是渭河的主要来沙支流。南岸支流较短,主要有石头河、黑河、涝峪河、灞河。流经土石山区,比降较大,水流湍急,泥沙以推移质为主 。河源至宝鸡峡出口为上游 ,河道狭窄,川峡相间,水流湍急;宝鸡峡至咸阳铁桥为中游,河床宽浅,沙洲较多,水流分散,为游荡性河床;咸阳至潼关河口为下游,河道蜿蜒曲折,单股无汊。中、下游渠道纵横,有泾惠渠、渭惠渠、洛惠渠等灌溉工程。处干旱、半干旱地区,年均降水量450~700毫米。多年平均径流量105亿立方米。6~10月为汛期,多暴雨。其中7、8、9三个月的径流约占全年的60%~70%。流域水土流失严重,水土流失面积约占流域面积60%~70%。多年平均含沙量为53千克/立方米。多年平均输沙量5.58亿吨,占黄河年输沙量的34.9%。泥沙主要来自葫芦河、泾河和洛河。 |
