Introduction: The purpose of this study is to reanalyze the navigation and flood channels of the Mississippi River by examining the arguments leading up to the series of man-made cutoffs, discussing their construction and illustrating the response of the system to the cutoffs. Engineers in many countries have looked on the Mississippi River cutoff program as one of extreme success but in trying to duplicate river shortening on other rivers have often produced disastrous results. The delicate balance among the hydraulic and geomorphic factors that control river form and river flow is so complex that it is not well understood. It is necessary then that there be as complete an understanding as possible of the response of a river after a single cutoff or a series of cutoffs. The success of the cutoff program on the Mississippi River can be partially attributed to the enormous amount of funds that have been spent in trying to hold the river in the alignment established by man. The cycle of response is still incomplete, and many of today's problems are a result of the man-made cutoffs of the 1930's and 1940's, plus a series of events, both natural and man-induced, dating back to the New Madrid earthquakes of 1811-1812.
