Erosion pins were installed on 32 banks in 5 tributaries of the Little River, eastern Tennessee, to quantify the contributions of streambanks to stream sediment loads and better understand the processes of streambank erosion. Streambanks lost material through subaerial erosion processes as well as by mass movements and removal of sediment by hydraulic forces. Initial results demonstrate that channel bank instability is widespread and channel banks are potentially important sources of sediment in these tributaries. Two observations made in this study, of streambank erosion independent of hydraulic forces and of bank undercutting active during drought, call attention to gaps in knowledge that affect models of streambank processes and efforts to improve water quality in headwater streams
