基于数学模型的辽宁省河流测流断面流量推求研究

摘要

Realizing the automatization of river profile flow is the tendency and research hotspot for the future development of hydrological test.In the paper,based on data about remote water levels,along with the hydraulic math model of one-dimensional river course,the profile flow of Dongling Hydrological Station and Gongzhutun Hydrological Station was calculated,compared and analyzed between them.The results show that using one-dimensional math model of river course hydraulics to calculate the flow of profile and two stations was better in fitting it,the error on simulated flood peak was less than ±10％,the relative coefficients were between 0.85 and 0.93.It is clear that this one-dimensional river course math model is suitable to calculate the profile flow of Dongling Station and Gongzhutun Station.The studied results will provide references for improving automatic collection and test on flow of river profiles.%实现河段断面流量自动化是未来水文测验发展的趋势和研究热点,文章基于遥测水位资料,运用一维河道水力学数学模型推求了辽宁省东陵水文站和公主屯水文站测流断面流量,并和两站实测流量进行了对比分析.研究结果表明,运用一维河道水力学数学模型推求的断面流量和两站实测流量具有较好的拟合度,模拟的洪峰误差在±10％之内,相关系数在0.85～0.93.可见,该一维河道数学模型可用于东陵站和公主屯站断面流量推求.研究成果可为河流断面流量自动化采集和测验方式的改进提供途径.
