  • The Influence of Lithology on Stream Metabolism in Mountain Systems

    Creator:
    Cargill, Samantha K.
    Abstract:
    Physical disturbance in streams has important effects on the metabolic rates of gross primary production (GPP) and ecosystem respiration (ER). Underlying lithology can control sediment size, amount, and evolution in the stream, influencing substrate stability and its effect on benthic organisms. We assessed the patterns of disturbance and recovery of...

  • Sediment transport modeling and implications for benthic primary producers in Oak Creek, OR

    Creator:
    Katz, Scott B.
    Abstract:
    The spatial and temporal variability of sediment transport processes in Oak Creek, OR was investigated and used to explore two study questions: 1) How do sediment transport processes influence benthic algal communities?, and 2) Can fluvial-hydraulic models make accurate predictions of bed load transport rates? Our study was conducted in...
