WATER LEVEL PREDICTION DEVICE, WATER LEVEL PREDICTION METHOD AND WATER LEVEL PREDICTION PROGRAM
To accurately predict the water level of a point having no past observation data on a river.SOLUTION: A water level prediction device 1 predicts a water level at a first point of a river at prediction object time after a predetermined period of time from the present time. The device has: an acquisition unit 11 for acquiring water quantity information regarding a water quantity including at least a water level of the time series before the present time at an observation point positioned upstream the first point; a first prediction unit 12 for predicting the water level at a second point upstream the first point at the prediction object time by using a water level prediction model composed by a statistical method, on the basis of water quantity information of the second point and of at least one observation point upstream the second position; a second prediction unit 13 for predicting the water level of the first point by a predetermined physical analysis method, on the basis of the predicted water level of the second point; and an output unit 15 for outputting the predicted water level of the first point.SELECTED DRAWING: Figure 1
