J. Rose Wallick
Rose Wallick is a hydrologist at the USGS Oregon Water Science Center.
Rose Wallick is a hydrologist and geomorphologist who joined the U.S. Geological Survey's Oregon Water Science Center in 2007. Beginning in fall of 2014, Rose has also been the Supervisor of the ORWSC Geomorphology Team. Her research draws upon geomorphic mapping, hydraulic modeling, sediment transport analyses and historical datasets to assess channel response to natural and anthropogenic influences.
While she has worked throughout Oregon, Rose's recent research is focused in the Willamette Valley where she is leading a major geomorphic mapping study and previously led a multidisciplinary effort summarizing geomorphic and riparian vegetation processes of the present-day floodplain. Rose has also played a key role in the environmental flow research and monitoring projects for the Willamette Sustainable Rivers Program. In these and other projects, Rose collaborates closely with the restoration community and the many ecologists, fish biologists and other geomorphologists active in the basin.
Prior to joining the USGS she worked as a hydraulic engineer developing 1D and 2D river models for DHI, Inc.

Geologic and physiographic controls on bed-material yield, transport, and channel morphology for alluvial and bedrock rivers, western Oregon
The rivers of western Oregon have diverse forms and characteristics, with channel substrates ranging from continuous alluvial gravel to bare bedrock. Analysis of several measurable morphologic attributes of 24 valley reaches on 17 rivers provides a basis for comparing nonalluvial and alluvial channels. Key differences are that alluvial reaches have greater bar area, greater migration rates, and shAuthorsJames E. O'Connor, Joseph F. Mangano, Scott A. Anderson, J. Rose Wallick, Krista L.

This report summarizes the current understanding of floodplain processes and landforms for the Willamette River and its major tributaries. The area of focus encompasses the main stem Willamette River above Newberg and the portions of the Coast Fork Willamette, Middle Fork Willamette, McKenzie, and North, South and main stem Santiam Rivers downstream of U.S. Army Corps of Engineers dams.

Rose WallickAn environmental streamflow assessment for the Santiam River basin, Oregon
The Santiam River is a tributary of the Willamette River in northwestern Oregon and drains an area of 1,810 square miles. The U.S. Army Corps of Engineers (USACE) operates four dams in the basin, which are used primarily for flood control, hydropower production, recreation, and water-quality improvement. The Detroit and Big Cliff Dams were constructed in 1953 on the North Santiam River. The GreenAuthorsJohn C. Risley, J. Rose Wallick, Joseph F. Mangano, Krista L.

The October 2007 breaching of a temporary cofferdam constructed during removal of the 15-meter (m)-tall Marmot Dam on the Sandy River, Oregon, triggered a rapid sequence of fluvial responses as ~730,000 cubic meters (m3) of sand and gravel filling the former reservoir became available to a high-gradient river.

The Umpqua River drains 12,103 square kilometers of western Oregon; with headwaters in the Cascade Range, the river flows through portions of the Klamath Mountains and Oregon Coast Range before entering the Pacific Ocean. Above the head of tide, the Umpqua River, along with its major tributaries, the North and South Umpqua Rivers, flows on a mixed bedrock and alluvium bed, alternating between bedrAuthorsJ.

This assessment of bed-material transport uses methods developed in a previous study (Wallick and others, 2010) to estimate bed-material flux at the USGS Chetco River streamflow gaging station located at flood-plain kilometer 15 (14400000). On the basis of regressions between daily mean flow and transport capacity, daily bed-material flux was calculated for the period October 1, 2008 to March 30,AuthorsJ. Rose Wallick, Jim E.

The October 2007 removal of Marmot Dam on the Sandy River, Oregon, triggered a rapid sequence of fluvial responses as ~730,000 m3 of sand and gravel that filled the former reservoir were suddenly exposed to an energetic river.

The lower Chetco River is a wandering gravel-bed river flanked by abundant and large gravel bars formed of coarse bed-material sediment. Since the early twentieth century, the large gravel bars have been a source of commercial aggregate for which ongoing permitting and aquatic habitat concerns have motivated this assessment of historical channel change and sediment transport rates.
