Watershed-Riparian Study - Willamette Basin

Land use & land cover relations with stream water quantity & water quality indicators.

To properly address water quantity and water quality concerns in riparian systems, we need a better understanding of the multiple ecological, hydrological, and land management interactions occurring in a given location. 

This project conducted primarily in the Oak Creek watershed, in the Willamette Basin, will provide critical information regarding the potential impacts that different land management practices (e.g., conservation programs and agriculture) may have on streamflow volumes and on several water quality indicators (e.g., stream temperature and nutrient levels). 

Project objectives are:

1) Characterize land use - water quality relationships across the stream longitudinal profile, from the headwaters to the watershed outlet.

2) Evaluate surface water and groundwater interactions at the field and watershed scales, and;

3) Assess the impact of specific land management practices (e.g., conservation programs, grazing) on soil, water, and vegetation indicators.  

We are monitoring multiple ecological and hydrological parameters to assess soil-plant-water relationships along the riparian zone and its contributing watershed.
