In the summer of 1993, record rains in the Midwest caused the Mississippi River to overflow its banks, break through levees, and inundate the entire countryside; such an inundation hadn't been seen for at least a hundred years. By contrast, the Nile River inundated its entire valley every year, bringing the rich black silt that made the valley one of the most fertile places on earth. (The inundations ceased with the completion of the Aswan High Dam in 1970.) Whenever a critical issue is being debated, the White House and Congressional offices are inundated with phone calls and emails, just as a town may be inundated with complaints when it starts charging a fee for garbage pickup.
Rising rivers could inundate low-lying areas.
water from the overflowing bathtub inundated the bathroom floor
