New generation flood forecasting in China: opportunity, research and challenge

摘要

This paper presents the idea of a new generation flood forecasting method and its key techniques, introduces the research progress in China, including CINRAD weather radar and precipitation estimations, the physically-based distributed hydrological model (Liuxihe model), and results from use in southern China. The challenges facing operational use of the new generation flood forecasting method in China were summarized as high resolution data acquisition, the uncertainties for flood forecasting, and real-time implementation environment and educational requirements.
