【摘要】 针对具有承担分洪调水任务的平原区连通河道,建立分洪调度模型。在满足本级河道防洪安全的前提下,提出定流量、上下游水位相应,以及上下游定水位、流量相应的2种调度方式;考虑可能出现的河道漫堤、冲刷塌岸等风险,以分洪流量、水位、冲刷流速等为控制条件,确定合理的调度参数。以连通德惠新河与马颊河的跃丰河为例进行调度设计,绘制流量~水位调度图,给出调度运用流程,为河道调度管理提供决策依据。更多还原

【Abstract】 Based on connective rivers in plain areas with flood diversion tasks,one flood diversion operation model is established.Two modes are proposed on the premise of flood safety,one is given flow with corresponding upstream and downstream water level,another is given water level with corresponding flow.Possible risks such as overtopping,bank collapse,etc.are considered.Control parameters are determined reasonably based on control conditions including diversion flow,water level and scouring velocity.Taking Yuefeng River,which conncets Dehuixin River and Majia River,as an calculation example,operation chart about flow and water level is drawn.The operation process is provided.更多还原
