The recent increase in rainstorm waterlogging disasters has acutely threatened the sustainable urban development. In this situation, it is particularly important to evaluation the risk of urban rainstorm waterlogging. Hence, the popular index system assessment was improved with greyanalytic hierarchy process (Grey-AHP), and then applied to assess the risk of rainstorm waterlogging. The improved index system consists of three levels: the target level, the criterion level and the index level. Moreover, the grey judgment matrix was constructed to evaluate the uncertain indices. Based on the Grey-AHP model, the evaluated index values fall in a relatively limited scope. The effect of the model was verified in a case study on Huangxiao River, central China's Hubei Province, with such impact factors as receiving waters, river storage capacity and runoff coefficient. The results prove the effectiveness of the proposed model, which offers a feasible method and lays the theoretical basis for urban rainstorm waterlogging risk assessment.
