Zusammenfassung: | To provide an adaptive division method for the rainfall runoff frequency in a period.SOLUTION: A method includes: a step S1 of collecting continuous rainfall runoff data in a known region; a step S2 of automatically calculating and recognizing peaks and valleys; a step S3 of automatically dividing the frequency of rainfall, recognizing the start and end times of rainfall, and calculating the cumulative rainfall amount every time; a step S4 of automatically dividing the frequency of rainfall runoff, and recognizing the start and end times of corresponding frequency of floods based on the start and end times of rainfall; a step S5 of recognizing the number of peaks in the single flood, and specifying the number of peaks in the flood based on the difference between the peaks and valleys in the single flood; a step S6 of calculating the correlation coefficient between the cumulative rainfall amount and the maximum increase range of flow rate in the single rainfall runoff; a step S7 of optimizing a parameter; and a step S8 of selecting a rainfall runoff process satisfying requirements.SELECTED DRAWING: Figure 1
【課題】本発明は、期間内の降雨流出回数の適応分割方法を提供する。【解決手段】この方法は、既知領域の連続的な降雨流出データを収集するステップS1と、ピークと谷を自動的に計算して認識するステップS2と、降雨の回数を自動的に分割し、降雨の開始及び終了時間を認識し、毎回の累積降雨量を計算するステップS3と、降雨流出の回数を自動的に分割し、降雨の開始及び終了時間に基づいて、対応する回数の洪水の開始及び終了時間を認識するステップS4と、1回の洪水のピークの数を認識し、1回の洪水におけるピークと谷との差に基づいて、洪水のピークの数を特定するステップS5と、1回の降雨流出の累積降雨量と流量の最大上昇幅の相関係数を計算するステップS6と、パラメータを最適化させるステップS7と、要件を満たす降雨流出プロセスを選別するステップS8とを含む。【選択図】図1 |
