| Abstract: | According to their current situations, the main influencing factors for the safety risks of small reservoirs are obtained. On this basis, a model for evaluating the safety risks of small reservoirs is established by using the machine learning method. The correctness and applicability of this model are verified through example analysis. The research shows that the evaluation of risk rates of small reservoirs based on the support vector machine has a certain applicability and can effectively solve the problem of short of data samples in their evaluation of safety rates. The research results may provide new ideas for the early warning of mountainous floods in the downstream regions of small reservoirs. |
