摘要/Abstract

摘要： 河床对水沙条件变化的滞后调整过程已被众多研究者通过实测资料分析所证实。以荆江河段上的监利站为研究对象,选定平滩面积作为反映河床调整的参数,通过分析河道平滩面积调整的滞后响应过程与特点,探讨其响应调整规律,并建立与之相适应的滞后响应模型。研究表明,监利站的前期来水来沙条件对当前平滩面积调整的影响真实存在,滞后响应理论同样适用于长江荆江河段的监利站。同时,通过对适用于黄河流域的滞后响应模型(即黄河滞后响应模型)进行改进,建立了适用于监利站的平滩面积滞后响应模型。

Abstract: It has been proved by analyzing the field data that the adjustment of riverbed in alluvial river is delayed due to variations of water and sediment load. In this paper, Jianli station in Changjiang river was selected as the research object. Through analyzing process and characteristics of delayed response of the bankfull area of Jianli station, we explore the regularity of area regulation response, and establish a delayed response model, which is suitable for the regularity. The results show that, influence of incoming water and sediment of Jianli station at early period on current bankfull area’s regulation really exists, and the delayed response theory can also be used to Jianli station, located at Jingjiang segment, Changjiang river. Meanwhile, after improving the delayed response model for Yellow river, we establish the modified delayed response model of bankfull area for Jianli station.

Key words: variations of water and sediment, alluvial river, Jianli hydrological station, bankfull area, delayed response, riverbed evolution
