Plankton and Benthic Instream-Flow Criteria, Strategy, and Habitat Delination in Acid-Containing Waters

摘要

Eight homogenous river segments were identified, through cluster analysis, in the upper Monongahela River Basin viz, Cheat Lake, Tygart Lake, an acid drainage segment of the middle Cheat, the lower Monongahela (to Pt. Marion, Pa), the upper Monongahela, the upper Cheat, the lower Blackwater River, and the Westfork River (south to Clarksburg, WV). Regression analyses of data from within these segments indicated that instream flow was highly associated with Total Algal Biomass in several of the segments. Regression analyses also showed that instream flow had very little association with the Algal General Distribution.
