Factors Influencing Streamflow Generation Processes in Rain-dominated, Coastal Watersheds in Oregon

Creator:

Pazdral, Rosemary

Abstract:

Relative to other systems in the PNW, the rain-dominated, coastal watersheds of western Oregon have shallow aquifers. Given the seasonality of streamflow and storage limitations in coastal, rain-dominated watersheds, changes in the temporal patterns of precipitation have the potential to magnify the risk of extreme streamflow conditions during both high-...

An Integrated Approach to Gauge the Effects of Global Climate Change on Headwater Stream Ecosystems

Creator:

Bury, Gwendolynn W.

Abstract:

Climate change is predicted to affect ecosystems, including systems already stressed by human impacts. One ecosystem that is already highly impacted by human land use is the cold headwater stream system of the Pacific Northwest. One method of assessing the function of an ecosystem is by using an indicator species....
