Geomorphology and Sediment Transport in the Eklutna River, Alaska Author: Dube, Kathy V., Watershed GeoDynamics Video Presentation Abstract A geomorphology and sediment transport analysis of the Eklutna River was conducted as part of comprehensive studies related to the 1991 Fish and Wildlife Agreement for the Eklutna Hydroelectric Project. Geomorphic and sediment transport processes in the Eklutna River downstream from Eklutna Lake have been altered by several management actions over the past century including water withdrawals, retention of sediment within constructed reservoirs, removal of the lower dam at River Mile (RM) 4, gravel removal from the river and floodplain, construction of the AWWU pipeline and access road, and channel confinement by roads and bridges. Sediment input, transport, and deposition are important processes that help to provide high quality aquatic habitat. An understanding of substrate conditions and sediment input and transport rates in the Eklutna River provides information that can be used to assess the effectiveness of potential future flow releases and aquatic habitat improvement measures under the 1991 Agreement. The geomorphology and sediment transport study included: Citation Please use the following citation when citing this presentation: Dube, K.V. (2023, March 6-8).
