Abstract

This study uses detailed aerial images, fieldwork and LiDAR data to link the modern geomorphology and channel hydraulics to specific variations in sediment transport, channel form, and avulsion behavior. Differences in discharge patterns are likely the most influential factor causing the meandering form of Lee Creek and the braiding channel of the Goggin Drain, 2 streams that are part of the Jordan River drainage into the endorheic Great Salt Lake of northern Utah. Although Lee Creek has not recently been avulsive, 3 major avulsions of the Goggin Drain have taken place since 1965. Two possible styles of avulsion are interpreted : an allogenic response to changing base level, and an autogenic response dictated by channel morphology and hydraulics. Despite a wealth of available information, avulsions cannot be unequivocally attributed to one style or another. Caution should be used when attempting to link the complex process of avulsion to causal mechanisms
