Embodiment Construction
[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.
[0039] In order to achieve the purpose and effect of the technical means, creative features, work flow, and use method of the present invention, and to make the evaluation method easy to understand, the present invention will be further described below in conjunction with specific examples.
[0040] Such as figure 1 As shown, a flood forecasting method based on ensemble Kalman filter: the improved ensemble Kalman filter is applied to the Xin'anjiang model, and the error between the calculated flow rate and the measured value of the outlet section of the watershed is obtained to obtain the calculated flow rate of the outlet section of the watershed. At the same time, the soil water content, free water...
