连云港市临洪水文站水位流量关系浅析

Brief analysis of stage discharge relationship about Linhong hydrological station in Lianyungang

临洪水文站作为河道站一直采用逐步图解落差指数法相关模型进行推流计算,单值关系精度较高,但由于附近水利工程改变而对原来的模型参数影响较大。本文通过分析2011~2015年该站实测流量资料,在新工情调度下的推流模型进行率定,利用正确的模型公式进行流量整编,判别出适合临洪水文站新工情调度下的定线推流方法——堰闸过水平均流速法。

As a river station, Linhong River hydrological station has been gradually using graphic index method model for flow calculation. Single valued relationship has high precision, but due to the change of water conservancy project nearby, the impact on the model parameters is large. In this paper, by analyzing the measured flow data of the station from 2011 to 2015, the flow model is calibrated under the new job schedule, and the correct model formula is used to compute the flow rate. Weir gate over horizontal mean velocity method is determined to be a suitable approach for Linhong hydrological station in the new project scheduling.
