Late Quaternary sedimentation and geologic history of the North Willamette Valley, Oregon

Creator:

Glenn, Jerry L.

Abstract:

Late Quaternary sediments in the Willamette Valley, Oregon, include a unit of chiefly silt and fine sand, the Willamette Silt Formation. Previous workers have (1) Assigned the Willamette Silt different ages which range from Sangamon interglacial to late Wisconsin glacial, (2) Proposed that the Willamette Silt was deposited in a...

Beyond the paired-catchment approach : isotope tracing to illuminate stocks, flows, transit time, and scaling

Creator:

Hale, V. Cody

Abstract:

This dissertation integrates a process-based hydrological investigation with an ongoing paired-catchment study to better understand how forest harvest impacts catchment function at multiple scales. We do this by addressing fundamental questions related to the stocks, flows and transit times of water. Isotope tracers are used within a top-down catchment intercomparison...
