  1. Removing Marmot Dam: From Monitoring To Learning Chuck Podolak Department of Geography & Environmental EngineeringThe Johns Hopkins University 2011 River Restoration Northwest Symposium

  2. Overview • Background • Measurements • -Who & What • What did we learn about putting together a large-scale monitoring effort Collaborators Peter Wilcock Smokey Pittman Gordon Grant Jon Major Jim O’Connor Rose Wallick Mackenzie Keith

  3. You are here Mt Hood

  4. Measurements • What • LIDAR • Topo Surveys • Local • Long Profiles • Grain Size Measurements • Pebble Counts • Bulk Samples • Aerial Photography • Repeat land-based photographs • Bedload Samples • Suspended Load Samples • Water Discharge Who • Johns Hopkins University / National Center for Earth Surface Dynamics • Oregon State University • Portland State University • USGS / USFS /BOR • Graham Matthews & Assoc • PGE • Dave Evans & Assoc • Watershed Sciences

  5. Transport Erosion Deposition

  6. Bringing it together

  7. Assembling a plan • Questions • Was it built as planned? • Did it change ___ in the river? • How did it change ___ in the river? • Tools • Surveys • Photography • Discharge measurements • LiDAR • Fish counts • Etc… ? Goal: Best array of tools to answer the desired questions -- with limited resources

  8. But… Only directional per method

  9. Combined USGS JHU / OWEB Combined PGE
