摘要
通过近几年实测资料的分析 ,得到了较为稳定的糙率值 经推流验证精度较高 。
Through anglyzing the observed data of recent years ,we obtain the stable relative roughness of this hydrologic station.The computed discharge verification shows that the accuracy is better.It provided the important reference for the feasibility of the slope area method in high water level in the Shizhenjie hydrologic station.
