Sediment and Nutrient Retention by Wetlands Receiving Inflows from a Mississippi River Diversion: A Mass Balance Approach

Diversions are currently used in the Mississippi River to stimulate delta growth via increased sediment supply. This technique may also help to reduce nutrient loads before its discharged into the ocean. Scientists at USGS assess how wetlands retain the sediment and nutrients that come from these diversions.

Hydrodynamics and Sediment Transport in Deltas and Coastal Wetlands

Diversions are being used to encourage Missippi River delta growth via increased sediment availability to coastal wetlands. USGS studies hydrodynamics and sediment transport in Louisiana to better understand how marshes and deltas respond to these sediment inputs.

Potential Impact of Hydrology and Sedimentation Changes to Biodiversity, Dongting Lake, China

Dongting Lake, one of the wetlands that make up the floodplains of China's Yangtze River, is important habitat for migratory waterfowl and other wildlife. However, the re-engineering of the water way and the intensification of agricultural practices has contributed to changes in hydrology and sedimentation. USGS and partners from China are assessing the potential impact of these changes to the...
