| 摘 要： | 依据实测资料,并结合流域地质、地貌特点,对窟野河泥沙输移与冲淤特征做了分析。结果表明,流域的地质背景及地面物质组成决定了流域高产沙的特征;产沙量与汛期水量有良好的相关关系;河床有周期性的揭河底冲刷特征;流域内分布特征不同的暴雨产生的泥沙对黄河干流的影响明显不同,在黄土区出现暴雨的情况下黄河干流会较快做出响应;近年来窟野河水沙量有显著减少的趋势,但存在稀遇暴雨下的增沙可能。

| Abstract: | Based on the measured data and the feature of landform and geology,sediment movement characters in Kuye River are analyzed.The results show that the characteristic of high sediment yield is determined by geological background and surface composition in watershed.The sediment load and flood season runoff has great correlativity.The riverbed has periodic scouring characteristic oftearing the riverbed off.The sediment generated by rainstorm with different distribution characteristics in the watershed has diffe... |
