Landscape Processes

The Willamette River Basin reflects the conflicting water demands between humans and ecosystems—particularly salmon— and the challenge resource managers face throughout the Pacific Northwest.

The USGS has been studying the Klamath Basin for decades. The USGS provides unbiased data to Tribal partners and resource managers to aid with complex management and conservation efforts.

Assessment of Sedimentation Changes in the Nehelam Bay, Oregon

The USGS has been documenting the geomorphic response to the annual Fall Creek Lake drawdown since 2011.

Assessing channel change, habitat health, and flood hazards across Oregon rivers and streams.

"The goal of this project is to characterize the vertical hydraulic gradient at the sediment-water interface in Upper Klamath Lake."

SPARROW can be used to relate water-quality data to landscape characteristics, such as natural properties and human activities

Sediment fingerprinting has been used successfully to identify land uses that are the major sources of sediment. This study will apply these techniques in a predominantly rural, volcanic landscape.

"SELDM facilitates analysis by providing precipitation, pre-storm streamflow, and other variables by region or from hydrologically similar sites."

In 2009, the USGS completed a comprehensive study of gravel transport and storage along the lower Chetco River.

Welcome to the Willamette River Study page. Here you will find links to USGS research for the Willamette River and the Willamette River Basin.

The USGS documents historical and current channel and floodplain processes and conditions to assist management and regulatory agencies in evaluating restoration proposals and designing effective restoration and monitoring strategies for the Sprague River and its principle tributaries. The study involves multiple analyses, including assessments of historical channel change, riparian and floodplain...
