Physical and chemical data on sediments deposited in the Missouri and the Mississippi River flood plains during the July through August 1993 flood Physical and chemical data on sediments deposited in the Missouri and the Mississippi River flood plains during the July through August 1993 flood
Because sediments deposited by the 1993 floods on the Missouri and Mississippi rivers were thought to contain elevated concentrations of nutrients and trace elements, sediment deposits were sampled at 25 floodplain locations. The samples were analyzed for particle size, water content, volatile solids, nutrients, carbon, selected trace elements, pesticides, and semivolatile organic...

Estimating flow rates to optimize winter habitat for centrarchid fish in Mississippi River (USA) backwaters Estimating flow rates to optimize winter habitat for centrarchid fish in Mississippi River (USA) backwaters
The backwaters of large rivers provide winter refuge for many riverine fish, but they often exhibit low dissolved oxygen levels due to high biological oxygen demand and low flows. Introducing water from the main channel can increase oxygen levels in backwaters, but can also increase current velocity and reduce temperature during winter, which may reduce habitat suitability for fish. In...
