Alaska Rivers Sediment Transport

GSTL staff, including Jon Nelson and Rich McDonald, are working closely with the USGS Alaska Science Center to support the use of the MD_SWMS modeling interface with ongoing projects including:

  • Modeling and Monitoring Streambed Scour at Alaska Bridges with Jeff Conaway. See McDonald and others, 2006; and Conaway and Moran, 2004.
  • Lower Copper River Dynamics and Geomorphology Project with Tim Brabets.

Example from Knik River: High resolution scour data from the Knik River will be used for validating the Sediment Transport and Channel Evolution modules currently in development for use in MD_SWMS.
