摘要
洪水運動可比喻爲飛彈來襲，而洪水演算則類似於從事飛彈攔截演算。本文利用自由落體運動及水文單位歷線例子，說明卡門濾波理論並不適用於水文演算，主要原因爲水文演算時並無預先鎖定的目標（洪峰）存在。故預測時並無法捉到眞值，而只是跟在實際歷線後頭而已。

Approaching flood can be likened to a oncoming missile, and flood routing is viewed as to build an anti-missile system. The applications of the Kalman filter to hydrologic models are not suitable. The Kalman filter fails to yield totally effective predictions in the hydrologic routing by the fact that any specific objective (peakflow) cannot be designated in advance. Without predetermined objectives, the predicted flows cannot catch the real values but follow the traces of the real hydrograph.
