Bringing it together

Assembling a planQuestions

• 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

Only directional

per method
