The increase of migration flows in the time of globalisation in the 20th and 21st century helps us to understand the dynamics of urbanisation (Zhang, 2015). The movement of people from rural areas to cities is so widespread and having tremendous impacts on the way we live and work. From the…show more content…
China urbanization background In the past decades, China has observed rapid urbanization, the nation 's urban population reached 50% in 2000, and is still in steady increase (Xu, 2015). Urbanization has an adverse impact on the urban hydrological processes, such as accelerating runoff flow velocity and enlarging peak flow (Li and Wang, 2009; Weng, 2001), thus increasing the urban flood risks. In the rapidly urbanized China cities, the increase of urban flood risks is obvious, and caused serious urban flood losses. Beside, as urban flooding causes sewer water over flow, flushes pollutant sand foul water to public area, it also causes health risks for the people who live there, such as causing epidemic disease breakout, polluting drinking water and damaging the living environment (Chen, 2014). Urbanization Issues Urbanisation has led to degradation of environmental quality especially the quality of water, air and noise. The domestic waste, industrial effluents and other waste that were dumped directly to the river have affected the water quality (Zhang, 2015). The environmental impacts of urban expansion reach far beyond urban areas themselves. In rapidly urbanising areas, agriculture intensifies on remaining undeveloped land and is likely to expand to new areas, putting pressure on land resources. Furthermore, urban areas change precipitation patterns at scales of hundreds of square
