  • Temperature and infiltration characterization of a constructed wetland for wastewater treatment

    Creator:
    Gregory, Christopher T.
    Abstract:
    The City of Woodburn, Oregon's Wastewater Treatment Plant (WWTP) has been investigating several natural alternatives for improving effluent quality. Based on its current National Pollution Discharge Elimination System (NPDES) permit, the WWTP will require additional reduction of temperature and ammonia levels in the summer, especially in the critical month of...

  • Infiltration and temperature characterization of a wastewater hyporheic discharge system

    Creator:
    Stewart, Ryan D.
    Abstract:
    The Clean Water Act imposes Total Maximum Daily Load (TMDL) limits on pollutant concentrations within wastewater effluent; in Oregon, thermal discharge is one of the pollutants subject to regulation. The City of Woodburn, Oregon, funded a series of pilot scale studies to investigate the utility of natural systems to reduce...

  • The effects of land use on mineral flat wetland hydrologic processes in lowland agricultural catchments

    Creator:
    Marshall, Sarah M.
    Abstract:
    Hydrologic processes within mineral flat wetlands, along with their connections to groundwater and downstream surface water in lowland agricultural catchments are poorly understood, particularly under different land uses. In the three field studies included in this thesis, we examined infiltration, wetland hydroperiod, groundwater recharge dynamics, surface runoff generation, and water...
