Bridge scour monitoring in Oregon

The U.S. Geological Survey is working with the Oregon Department of Transportation (ODOT) and Federal Highway Administration (FHWA) to revolutionize bridge scour monitoring using real-time sonar data collection and bathymetric surveying to remotely monitor sites, collect long-term data for evaluation, and develop and improve hydraulic models that predict scour.

Fern Ridge Geomorphology

The USGS, in cooperation with the U.S. Army Corps of Engineers (USACE), is conducting targeted research to better understand geomorphic conditions and processes within the reservoir at Fern Ridge Lake, near Eugene, Oregon, so that managers have the information to support dam operations and other actions that will aid in the preservation and management of cultural sites.

Upper Klamath Basin Groundwater Studies

Since the late 1990s, USGS has worked to characterize the regional groundwater hydrology of the upper Klamath Basin. Research focuses on collecting data to evaluate the groundwater system and its response to external stresses, and to develop computer models that provide insights for water management. These efforts build on earlier USGS studies going back to the 1950s.

Multiscale comparison of hyperspectral reflectance from periphyton in three Oregon rivers used for municipal supply

In this study, USGS scientists from multiple centers used advanced hyperspectral imaging techniques to advance monitoring of attached benthic algae (periphyton) in Cascade Range rivers used for municipal water supply. Periphyton are naturally occurring, but excess growth can harm ecosystems and degrade raw and treated drinking water quality. In these rivers, periphyton contain cyanobacteria that...

Estimating Groundwater Budgets for Oregon

Scientists Stephen Gingerich and Adel Haj, Jr. are leading efforts to estimate groundwater budgets across the state. Water hidden beneath the earth’s surface is a vital resource and quantifying its availability is crucial for long-term management. USGS scientists are collaborating with scientists at the Oregon Water Resources Department to gain a better understanding of this valuable resource.

Walla Walla River Basin groundwater-flow system, Oregon-Washington

The Issue: Decades of declining groundwater levels in the Walla Walla River Basin (WWRB), which spans Oregon and Washington, are affecting instream flows for threatened and culturally important fish populations and water availability for competing interests across state lines. The public and state resource management agencies have begun implementing efforts to stabilize groundwater levels and...
