[0024] Example 1
[0025] The dissolved oxygen saturation prediction of the Huangling Miaojiang section, the Miaozui section of the downstream of the Three Gorges Dam discharge, and the waters in front of the Gezhou Dam is used as an embodiment of the present invention, and a BP neural network-based dissolved oxygen saturation prediction is combined with the embodiment. The method is described in detail.
[0026] This embodiment is a method for predicting dissolved oxygen saturation based on BP neural network. The structure of BP neural network is as follows figure 1 As shown, the process is as figure 2 As shown, including the following steps:
[0027] (1) Determine the main influencing factors of dissolved oxygen saturation at a fixed point downstream of the high dam.
[0028] The influencing factors of the dissolved oxygen saturation of the downstream channel of the high dam discharge determined in this example are quantified as x1 the dissolved oxygen saturation on the Three Gor...
