HYDROLOGY AND CLIMATE CHANGE IN THE MISSISSIPPI RIVER BASIN
 
In the Mississippi River basin, engineered changes along the river and alterations of the watershed began in the 18th century when levees were built to protect the soon-to-be developed city of New Orleans. Since then, anthropogenic changes to the River and its watershed have continued, and proceeded at a rapid pace after the 1927 flood. Most of the Lower Mississippi River floodplain is now leveed and much of the Upper Mississippi River watershed within Illinois and Iowa has been drained for agricultural purposes. These changes have had significant impact on solute transport and flow in the River. Analysis of river flow and discharge measured at Vicksburg, Mississippi by the Army Corps of Engineers since 1818 shows a non-stationarity in total annual River discharge, with an increase during the past few decades. Others have shown that there has been an increase in precipitation in the upper portions of the Mississippi River watershed. These possibly climate change-related effects on river flow will be discussed in terms of solute transport in the river.
