Seasonal relationships between dissolved nitrogen and landuse/landcover and soil drainage at multiple spatial scales in the Calapooia Watershed, Oregon

Creator:

Floyd, William C.

Abstract:

The Calapooia River, a major tributary of the Willamette River in western Oregon, is a watershed typical of many found in the Willamette Basin. Public and private forested lands occur in the steep Upper Zone of the watershed, mixed forest and agriculture lands are found in the Middle Zone, and...

Dissolved nitrogen in surface waters and nitrogen mineralization in riparian soils within a multi-land use basin

Creator:

Evans, Daniel M.

Abstract:

The growing population of Oregon’s Willamette River Basin places an increasing demand on the basin’s surface waters. Watershed-scale research addressing spatial trends of dissolved nitrogen (DN) and its relationship with landuse and soil N dynamics, such as N mineralization, is sparse in the Willamette Basin. I measured DN along 124...
