The Mississippi River Basin is a vital region spanning over 1.2 million square miles, nearly half of the continental United States. The river itself stretches more than 2,300 miles from near the Canadian border to the Gulf of Mexico, serving as a lifeline for millions of residents who depend...
However, the impact of basin size and river network structure on C-Q relationships is not well characterized. Here, we show, using high-resolution nitrate concentration data, that tile drainage is a dominant control on C-Q dynamics, with increasing drainage density contributing to more c...

The river’s ecology has long dealt with challenges such as industrial and agricultural pollution, habitat destruction and prolific spread of invasive species. Part of the difficulty in addressing these problems come from the sheer size of the basin, with its geography covering over a third of the...
Scatterplots and linear regressions with 1σ prediction intervals relating normalized EM score (a measure of grain size) to peak annual discharge of historical flood events for (a) MRY, (b) FLR and (c) STJ. Peak annual discharge estimates are from the Mississippi River gauging station at Vic...
Mississippi River Facts Mississippi River Overview The Mississippi River is one of the world’s major river systems in size, habitat diversity and biological productivity. It is the third longest river in North America, flowing 2,350 miles from its source at Lake Itasca through the center of the...
A single hopper barge can carry as much dry cargo as16 rail cars or 70 trucks. About 92% of U.S. agricultural exports, including soybeans, corn and wheat,move through the Mississippi River Basin. Low water levels reduce the navigable portions of the river that are deep enough for barges...

We tracked 730 ponds on the Mississippi River Deltaic Plain (MRDP) from 1982 to 2016 to understand how they are changing shape and size. Our results show that 64% of ponds (n = 469) are expanding. The expansion direction is predominantly toward the SW (201°), which is similar to the...
