| Abstract: | With Yang chizhong's filtering estimation method, the filtering of the observed value sequence is made once and again by binomial coefficient weighted moving average. The mathematical model of the estimate value is established and the elevation difference of each square grid center is derived. According to difference between design elevation of reservoir' spillway and elevation of each square grid center, the volume of each square grid is calculated and collected, the reservoir cubage is obtained accordingly. The processing algorithm of anomalistic boundary is discussed. |
