Retrospective Theses and Dissertations

The tall-grass prairies, wetlands and forests that dominated the Iowa landscape have been replaced by annual row-crops and grass pastures that occupy more than 90% of the landscape today. Because of these changes, water reaches streams and gullies much faster and has led to incised streams and an extensive growth of gully networks. Stream and gully banks are major contributors of non-point source sediment and phosphorus. Reducing these pollutants is a priority to maintaining healthy streams. The objective of this study was to compare stream and gully bank soil and phosphorus losses under different land-use practices in three Iowa regions ...
