Spatial And Temporal Changes In Stream Chemistry At Three Watersheds During High Discharge Episodes, Mollie Kate Laird

Electronic Theses and Dissertations

A longitudinal study of first order streams in three forested watersheds was conducted to determine spatial and temporal trends in geochemistry during high discharge acidic episodes. The watersheds were East Bear Brook and Hadlock Brook (Maine, USA), and Fernow WS3 (West Virginia, USA). Watersheds were selected based on soil type, stream pH, and historical chemistry. Stream sampling sites were distributed along an elevational gradient and sampled simultaneously during a high discharge episode. Base flow samples were collected prior to the start of the hydrological event. The Maine watersheds, East Bear Brook and Hadlock Brook, were sampled during fall 2005 rain …
