摘要:
水位流量关系的确立是一个难题,利用曼宁公式求解会产生较大误差.文中利用基于差分方程的系统辨识方法,描述稳定河道的水位流量关系; 利用实测水文数据与现有的各种方法进行对比研究.仿真结果表明,该方法可以较好地提高对水文数据的拟合精度.
Abstract:
To establish relationship between water level and water flow is a difficult problem,and to solve by using Manning’s formula will engender fairly great error.The authors describe the relation between water level and water flow of a steady river course by using the method of difference equation-based system identification; and carry out a comparative study by using measurement of hydrological data and various methods now available.As indicated by simulated results,the method notably improve the precision of fit of hydrological data,it is of effectiveness and usability.
