Schaake Project

• Purpose – to improve habitat conditions and address potential flooding issues

  • Two reports to YRBWEP
  • Interim report detailing a geomorphic study
    • Included a historic and geomorphic study of previous channel forms and locations using 1912 survey and 1966 aerial photography
    • Determined the level of channel incision and anticipated frequency of floodplain inundation using a 1-D hydraulic model and 27 years of gage data
  • Final report detailing proposed levee setback and pilot channel locations
    • Three levee scenarios modeled in two dimensions to evaluate flooding
    • Smaller scale 2-D model to study interaction between pilot channels and main channel
