Effects of urbanization on timing of flood peaks on Town Creek in Jackson, Mississippi

During the floods of March and April 1969 the flood crest on Town Creek occurred at Gallatin Street before crests occurred at some upstream points. Heavy urbanization in the downstream part of the basin probably caused the abnormal sequence of flood peaks in Town Creek.

Flood flow at Gallatin Street is spread over a greater length of time and the peak discharges caused by urbanization in the lower part of Town Creek basin seem to be lower than those that might be expected if the basin were more uniformly urbanized.
