| Abstract: | Based on the need for flood control and water hazard mitigation, the research to improve the precision of forecasting flood-peak has been done, and a peak magnifying coefficient and the optimizing network's original weight by genetic algorithm are also presented. The test result has shown that the improved method is effective and reliable. |
