Sediment retention in a bottomland hardwood wetland in eastern Arkansas
B.A. Kleiss
1996, Wetlands (16) 321-333
One of the often-stated functions of wetlands is their ability to remove sediments and other particulates from water, thus improving water quality in the adjacent aquatic system. However, actual rates of suspended sediment removal have rarely been measured in freshwater wetland systems. To address this issue, suspended...
