Title:
ADVERSARIAL NEURAL NETWORK-BASED HYDROLOGICAL PARAMETER CALIBRATION METHOD FOR DATA REGION
Document Type and Number:
WIPO Patent Application WO/2022/032874
Kind Code:
A1
Abstract:
An adversarial neural network-based hydrological parameter calibration method for a data region, comprising: collecting soil texture, vegetation coverage, a land utilization rate, topographic data, a runoff coefficient, total annual evaporation, and gradient and slope data; dividing a calibration region into computing units of less than 30 square kilometers; determining each underlying surface parameter of each computing unit and a meteorological related factor; and performing automatic calibration on hydrological parameters of a data watershed by using an adversarial neural network GAN to obtain an optimal hydrological parameter of each computing unit. The technical problems in the prior art such as the work is repetitive, the efficiency is low, the complexity is extremely high, and the application and popularization of a hydrologic model are not utilized are solved.
