Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings.
[0026] Such as Figure 1-Figure 3 As shown, a multi-variable flood return period calculation method considering reservoir flood regulation calculation method collects the maximum flood process data and flood peak and flood volume series of the reservoir over the years, and inputs the reservoir to carry out flood regulation calculation statistics according to the regulation rules to obtain the annual maximum water level series. Using genetic programming to perform symbolic regression to deduce the explicit expression of the flood control function of the reservoir, and use the Copula function to solve the joint probability density function, and then integrate the joint probability density function in the safe area to obtain the cumulative probability of the highest water level in the specified year , so as to calculate the univariate return period of the maximum water le...
