Future risks of urban flooding is increasing in conjunction with continued increases in global surface temperature  . In particular, Asian cities are highly exposed to future flood risks arising from urbanisation processes. Between 2000 and 2030, rapid urbanisation in Indonesia will elevate flood risks by 76-120% for river and coastal floods, while sea level rise will further increase the exposure by 19-37% . In Can Tho, Vietnam, current urban development patterns put new assets and infrastructure at risk due to sea level rise and river flooding in the Mekong Delta . Flooding in urban areas is exacerbated both by the encroachment of urban areas into areas that retain water and by the lack of infrastructure such as embankments and flood walls, as is the case for large areas of Dhaka East . Zhou et al.  have also shown that for the city of Hohhot, China, the increase in impervious surfaces contributes between 2-4 times more to modelled annual flood risk compared with risk induced by climate change.
