  • Feasibility of Thermal Restoration by Groundwater Additions in the Middle Fork John Day

    Creator:
    Hale, Abigail E.
    Abstract:
    Survival of ecological systems pivot on critical moments. In the arid John Day Basin of Eastern Oregon, extensive restoration of the stream and floodplain focused on supporting salmon has been ongoing for the past 20 years, but recurring short periods of extreme temperature increase and low flows result in mortality...

  • Understanding Aquifer Water Retention Dynamics Using Groundwater Head Relaxation Time

    Creator:
    Jimmie, Jordan A.
    Abstract:
    Diking and channelizing in the Toppenish Creek basin, associated with irrigated agricultural development, has altered its natural ecosystem function and hydraulic processes. We seek to answer two research questions: if surface waters are diverted for aquifer recharge in the winter, will this water be available for ecosystem function in the...
