Transport Erosion Deposition
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
But… Only directional per method
