Method for predicting tidal estuary water level process
The invention discloses a method for predicting a tidal estuary water level process. The method comprises the following steps: 1, forming a 'water level (eta)-time (t)' relation sequence; 2, acquiring a 'water level (eta)-time (t)' relation sequence of any position of the estuary region; 3, obtaining a convolution result of a water level time sequence corresponding to each time-frequency domain; 4, obtaining a W(s) accumulation result corresponding to each partial tide cluster period; 5, reconstructing a water level time sequence corresponding to the moisture cluster of each period; 6, representing the water level process of the specific spatial position in the step 3; and 7, repeating the steps 3-6, and determining a water level process relational expression of any spatial position, so as to realize the prediction of the tidal estuary water level process. According to the tidal estuary water level process prediction method provided by the invention, the defects of insufficient prediction precision and representativeness can be overcome, and the accuracy and applicability of estuary hydrological station historical data in water level (tide level) prediction application are improved.
