| Abstract: | The principle and computational derivation of polynomial weighted average interpolation method are introduced.The polynomial weighted average method is combined with quadratic parabolic fitting method to calculate the water level,and the calculation results are judged by using Laida criterion and Schawler criterion.The statistical results show that the polynomial interpolation method and the quadratic parabola fitting method are suitable for water level estimation,and better results can be obtained. |
