Abstract

In this study, we used hydrological alteration diagnosis system to acquire the flood variation form and degree of Xuanen County under changing environments, and analyzed its cause mechanisms using the formula of Chézy-manning. The results showed that: firstly, the annual maximum daily flow series from 1962-2013 jumped a downward moderate variation in 1999, which indicated that the dual influence of human activities leaded to the variation of the annual maximum daily flow. Secondly, river canalization has started in 2005 and completed in 2012, which has reduced the flood discharge at equal water level, aggravating the flood variation to a certain extent. Finaly, human activities have great influence on the flood control abilities of urban water bodies of Xuanen. Xuanen County river canalization resulted in decrease of the flood flow, exacerbating the variation of flood, thereby the flood warning plan needed to adapt to the changing environment, which would make river flood prevention decision more scientific and feasible.
