Water Quality

Minimum Detection of Change (MDC)

The focus of this project is to determine the likelihood of detecting change in water quality resulting from stream restoration. Often it is unlikely that improvement in water quality will be detected within mitigation time frames due to various watershed characteristics. 

Our objective is to understand reach and watershed attributes that make detecting change probable to help the mitigation practitioners tailor and develop scientifically valid goals for a given project.
