During the flood season of 2016, the middle and lower reaches of the Yangtze River suffered the worst flooding since 1999, involving Hunan, Hubei, Anhui, Jiangxi and Jiangsu provinces and the Taihu Basin. Based on the field survey at eight counties on both sides along the Yangtze River in Anhui Province, this paper analyses the features of rainstorm, flood and the resulting disaster in 2016 over there, and identifies problems and difficulties existing in flood prevention and disaster reduction under the new situation of social and economic development. Furthermore, this paper discusses the coping strategies and measures on advancing the comprehensive flood management mode of human-water harmony, managing middle and small rivers and strengthening the key basic research on flood control and disaster reduction under the new situation.

The present paper focuses on the variation of the annual streamflow and sediment fluxes in the Yangtze River basin from 1956 to 2009 using annual observations at 10 hydrological gauging stations. Both simple linear regression analysis and the Mann-Kendall test are applied to the time series for trend detection, and the relations between streamflow and precipitation and between sediment flux and precipitation are analyzed with the help of a double mass curve function. The results present differing trends of changes in streamflow and sediment. [ABSTRACT FROM AUTHOR]

This study analyzes changes in global radiation in the Yangtze River basin during 1961 to 2010. Global radiation decreased significantly from 1961 to 1989 and increased from 1990 to 2010, which has been described as “from dimming to brightening”. The analysis indicates that changes in fuel consumption were responsible for the variation in global radiation, while changes in meteorological variables had a limited contribution. The impact of changing global radiation on the water cycle is discussed. The change in global radiation was possibly the main cause of changes in potential evapotranspiration, which also decreased from 1961 to 1989 and increased from 1990 to 2010. [ABSTRACT FROM AUTHOR]
