|Elwha River Restoration Project Sediment Management near Port Angeles, WA|
|Removal of Glines Canyon Dam||Sand and gravel is being transported through the former Lake Mills||Sand and gravel exposed in the former area of Lake Mills|
|The Elwha now flows free past the former site of Elwha Dam||Surface diversion weir on the Elwha River includes bedload impact sensors to continuously measure the transport of gravel||Elwha River below the dams will soon receive the first supply of gravel from the upstream watershed in 100 years|
The Sedimentation and River Hydraulics Group conducts studies on how rivers and reservoirs have or will respond to changes in river flow, sediment supply, or channel modification. Studies are prepared for a variety of purposes including operation and maintenance, dam safety, and fish and wildlife habitat restoration. Many studies focus on Reclamation facilities; their physical impact on river channels and endangered species habitat, recreation, wetlands, and cultural resources.
This Group assists in planning effective water and sediment management programs including:
- Reservoir sedimentation surveys
- Reservoir sustainability
- Sediment management studies for rivers, reservoirs, and structures;
- Environmental impact studies;
Our ability to collect and analyze data, identify and simulate physical processes, apply a range of models, and synthesize results for complex systems places Our Group in a unique class among river consultants.
Our Group includes 17 Hydraulic Engineers who specialize in river hydraulics, sedimentation transport, and computer modeling; 3 Geomorphologists who specialize in river processes, and 3 Physical Scientists who specialize in the analysis of spatial data. Nearly every eligible Engineer has a professional engineer license. Of the 23 staff, 20 have a Master of Science degree, 1 is a Ph.D. candidate, and 7 have Ph.D. degrees.

The Federal Interagency Conference on Sedimentation and Hydrologic Modeling will be held March 23 to 27, 2014 Reno, Nevada. The theme is Sustainable Water Resources in a Changing Environment. Abstracts are due March 1, 2013.
Our group capabilities are summarized below:
- Reservoir and river channel surveys;
- GIS and data analysis;
- Geomorphic analysis;
- Research and development:
- Numerical model development,
- River channel process investigations, and
- River structure design criteria;
- Numerical Modeling (1D, 2D, and 3D):
- River and floodplain hydraulics,
- Sediment transport,
- Channel migration, and
- Vegetation and habitat;
- Environmental impact analysis
Sediment impact studies of rivers and reservoirs link changes in stream flow and sediment supply to processes controlling changes in channel shape and bank erosion. Applied research and customized investigations range from simple technical advice to in-depth, multi-year studies integrating diverse disciplines.
Many of our investigations focus on the hydraulic and sediment impacts to fish and wildlife habitat, recreation, wetlands, or cultural resources and can incorporate assessment, planning, and design of water resource facilities. We frequently participate in inter-disciplinary and interagency teams in evaluating ecological systems and providing input for environmental impact statements and assessments.
We use a wide range of modeling and analysis software including an extensive suite developed and maintained in-house. Our in-house software allows us to customize and optimize numerical models to solve specific problems. We have designed our software to work together and provide an integrated view of river hydraulic and morphological processes. View our Model Development pages for the latest information.
We are available to assist you with reservoir and river sedimentation, river restoration, channel stabilization, and river hydraulics problems associated with water resources development, planning and management, dam safety, and river ecosystem restoration.
