| 摘 要： | 将渭河下游按照纵比降变化情况分为上、中、下三段，分别是陡坡段、过渡段和缓坡段，认为沿程冲淤会影响整个河段，溯源冲淤主要影响中、下段；1990年以来渭河下游的持续堆积主要是由来水来沙变化引起的，持续淤积使潼关高程持续抬高，从而也加重了渭河下游中、下段的淤积；并与黄河下游纵剖面的变化进行了对比。 |
| 关 键 词： | 泥沙淤积 纵剖面 比降 渭河下游 |

| Abstract: | The lower Weihe River is divided into three reaches based on the longitudinal profiles. The upper reach is steep, the middle is transition and the lower is mild. Scour and siltation due to variation of flow and sediment occur along the whole lower river, and scour and siltation due to variation of river mouth mainly happen in the middle and lower parts of the river. Variations in flow and sediment have resulted in progressive siltation along the lower Weihe River. The changes of profiles is similar with those of the lower Yellow River. |
| Keywords: | siltation longitudinal profiles the lower Weihe River |
