METHOD OF performing REAL-TIME CORRECTION OF A WATER STAGE FORECAST

A method of performing real-time correction of a water stage forecast, the method comprising:

• obtaining at least one predicted water stage of at least one time and a predicted water stage of a next time after the at least one time, wherein a previous time of the at least one time is a current time;
• obtaining at least one observed water stage of the at least one time;
• generating a system error of the water stage forecast according to the at least one observed water stage of the at least one time, the at least one predicted water stage of the at least one time, the predicted water stage of the next time, a Time Series method, and an Average Deviation method;
• utilizing a Kalman filter method to generate a random error of the water stage forecast;
• generating a water stage forecast correction of the next time according to the system error and the random error;
• and
• correcting a predicted water stage of the next time according to the water stage forecast correction of the next time and the predicted water stage of the next time.
