Abstract: Human activity produces distinct patterns within urban watersheds. In some low-relief urban watersheds, road networks frequently emerge as localized topographic highs in the landscape that rearrange the boundary of the watershed and increase the conformity between the stream network and road network. This study introduces and applies a geospatial metric to assess levels of correspondence between watershed characteristics (stream network, watershed boundary) and road network. A modified version of the automated proximity and conformal analysis is used to highlight areas of high, medium, and low conformity between linear features within the Rouge River watershed, a highly urbanized watershed in southeast Michigan. Watershed boundary and stream networks were extracted using high-resolution (
