Abstract:

 Combined with the existing method in determining the level of urban flood warning, a model was proposed. This model used the multiple linear regression method. It considered the interaction of many impact factors in determining the level of urban flood warning. It has a high correlation among the impact factors. It used the typical rainfall data of Jinan City to test the accuracy of the model. The result showed that this model has a good effect. This model can be used in the urban area of Jinan City to determine the level of flood warning.

Key words:  multiple linear regression, Spearman rank correlation, least squares method, flood warning level
