dc.descriptionAbstract: Long-term bank erosion rates and channel changes in a 14-km stretch of the Tanana River centered on Goose Island were documented using historical aerial photography from 1938 through 1982. The construction effects of a causeway partially blocking the river and the time required to return to equilibrium after construction were studied. Erosion, averaged over the entire study reach, was not significantly different following causeway construction compared to that prior to construction. Significant short-term increases in localized erosion rates during post- vs pre-construction time periods were documented in south channels and islands downstream of the causeway. Deposition upstream of the river constriction formed by the causeway was dramatic. The Tanana River returned to near equilibrium by 1980, five years after the construction of the causeway, with some effects continuing in 1982. Due to additional in-river construction downstream of the study area in 1981, the separate effects from the causeway could not be monitored beyond 1982.-
