摘要
运用开源的河冰数值模型RIVICE模拟黄河三湖河口弯道段2008—2010年开河期的冰塞水位,并进行模型参数的敏感性分析。研究所使用的流量、水位、冰厚等数据均来自水文年鉴。结果表明,用RIVICE模型模拟开河期冰塞水位具有很高的可行性。冰塞回水水位对上游边界流量十分敏感,说明了水利工程调控的重要性,研究通过数值模型对冰塞水位进行模拟及演变预测,为水利工程调控和凌汛防治提供一定的参考。
In this study,the open-source numerical river ice model RIVICE was used to simulate the ice jam water level in the Sanhuhekou bend reach of the Yellow River during the break-up period.Its parameters were then subjected to sensitivity analysis.Flow,water level,and ice th ickness were obtained from the Hydrological Yearbook.Results show that the RIVICE model can be utilized to simulate the ice jam water level in the break-up period.The backwater level of an ice jam is highly sensitive to the upstream boundary discharge,indicating the importance of water conservancy projects in flow regulation.Therefore,the established model can provide a scientific theoretical basis for managing water conservancy projects and ice flood control.
