Flood risks in settlements arise from hydrometeorological events interacting with the urban system which exposes settlements to river  floods, flash floods, pluvial  floods, sewer floods, coastal floods and glacial lake outburst floods . Sea level increase and increases in tropical cyclone storm surge and rainfall intensity will increase the probability of coastal city flooding  . Globally, the increase in frequencies and intensities of extreme precipitation from global warming will likely^ expand the global land area affected by flood hazards  ; Section 4.2.4.2). Mishra et al.  noted that out of 241 urban areas, only 17% of cities experienced statistically significant increases in frequencies of extreme precipitation events from 1973 to 2012. In the future, there is some evidence that changes in high-intensity short duration  rainfall in urban areas will increase  .
