Abstract: The Huaihe River Basin Flood Management and Drainage Improvement Project was taken as the study object. The characteristics of the geography, climate, economy, society, river systems and flood control systems etc. within the Huaihe River basin have been comprehensively analyzed. It is realized that, among the three types of floods in the Huaihe River basin, the flood caused by consecutive rainfall for more than one or two months may have the most obvious negative effect on the agricultural development in the low-lying areas and on the benefits of the project under the impacts of climate change. A semi-quantitative analysis for possible impacts of climate change is presented, and some adaptive measures of both enhancing the drainage capacity and raising the adaptive ability are put forward.

Key words: climate change, Huaihe River basin, flood control and land drainage, low-lying area, adaptive measures
