Abstract Cities have historically developed close to rivers and coasts, increasing human exposure flooding. That is exacerbated by changes in climate population, urban encroachment on floodplains. Although the mechanisms of how urbanization affects flooding are relatively well understood, there been limited efforts assess magnitude floodplain globally it has changed both space time.

Floodplains play a key role in the ecology of the Upper Mississippi River; however, humans have significantly affected the ecological function of floodplains by isolating them from the main stem of the river with levees. Impoundment and channel training within the main stem also influence floodplain function by altering the flow of water through the system. Because of the key role hydrology pla...
