Shoals and valley plugs in the Hatchie River watershed
Timothy H. Diehl
2000, Water-Resources Investigations Report 2000-4279
Agricultural land use and gully erosion have historically contributed more sediment to the streams of the Hatchie River watershed than those streams can carry. In 1970, the main sedimentation problem in the watershed occurred in the tributary flood plains. This problem motivated channelization projects (U.S. Department of Agriculture, 1970). By...
