Science and Products
The quantity and quality of streamflow in transboundary watersheds of Southeast Alaska are important to many stakeholders. Development and operation of several mines in Canada have increased the interest in current and future conditions in these watersheds. The USGS Alaska Science Center operates streamflow information stations on the Alsek, Chilkat, Taku, Stikine, and Unuk Rivers. Real-time...
The USGS conducts various studies of streamflow statistics for data collected at streamflow-gaging stations. Streamflow statistics for gaged streams and methods for estimating those statistics for ungaged streams are used by water resource planners and managers for designing infrastructure, managing floodplains, and protecting life, property, and aquatic resources. The most recent USGS studies...
The Cook Inlet Basin (COOK) study unit in southcentral Alaska, is part of the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program. The long-term goals of this program are to describe the status and trends in the quality of a large, representative part of the Nation's surface- and ground-water resources, and to provide a sound, scientific understanding of the primary...
This page will serve as the repository for data collected by the Cook Inlet Basin NAWQA team using NAWQA sampling protocols. Data sets collected using NAWQA protocols but not collected as part of the Cook Inlet Basin NAWQA program are identified with an asterisk (*). A list of ...

Using remotely sensed data to estimate river characteristics including water-surface velocity and discharge
This paper describes a project combining field studies and analyses directed at providing an assessment of the accuracy of remotely sensed methods for determining river characteristics such as velocity and discharge. In particular, we describe a remote sensing method for surface velocities using mid-wave thermal camera videography combined with...Nelson, Jonathan M.; Kinzel, Paul J.; Legleiter, Carl; McDonald, Richard R.; Overstreet, Brandon; Conaway, Jeffrey S.
Remote measurement of surface-water velocity using infrared videography and PIV: a proof-of-concept for Alaskan rivers
Thermal cameras with high sensitivity to medium and long wavelengths can resolve features at the surface of flowing water arising from turbulent mixing. Images acquired by these cameras can be processed with particle image velocimetry (PIV) to compute surface velocities based on the displacement of thermal features as they advect with the flow....Kinzel, Paul J.; Legleiter, Carl; Nelson, Jonathan M.; Conaway, Jeffrey S.
Evaluation of streambed scour at bridges over tidal waterways in Alaska
The potential for streambed scour was evaluated at 41 bridges that cross tidal waterways in Alaska. These bridges are subject to several coastal and riverine processes that have the potential, individually or in combination, to induce streambed scour or to damage the structure or adjacent channel. The proximity of a bridge to the ocean and water-...Conaway, Jeffrey S.; Schauer, Paul V.
Oceanographic gradients and seabird prey community dynamics in glacial fjords
Glacial fjord habitats are undergoing rapid change as a result of contemporary global warming, yet little is known about how glaciers influence marine ecosystems. These ecosystems provide important feeding, breeding and rearing grounds for a wide variety of marine organisms, including seabirds of management concern. To characterize ocean...Arimitsu, Mayumi L.; Piatt, John F.; Madison, Erica N.; Conaway, Jeffrey S.; Hillgruber, N.
Streamflow and streambed scour in 2010 at bridge 339, Copper River, Alaska
The Copper River Highway traverses a dynamic and complex network of braided and readily erodible channels that constitute the Copper River Delta, Alaska, by way of 11 bridges. Over the past decade, several of these bridges and the highway have sustained serious damage from both high and low flows and channel instability. This investigation...Conaway, Jeffrey S.; Brabets, Timothy P.
Kittlitz’s and Marbled Murrelets in Kenai Fjords National Park, south-central Alaska: At-sea distribution, abundance, and foraging habitat, 2006–08
Kittlitz’s murrelets (Brachyramphus brevirostris) and marbled murrelets (B. marmoratus) are small diving seabirds and are of management concern because of population declines in coastal Alaska. In 2006–08, we conducted a study in Kenai Fjords National Park, south-central Alaska, to estimate the recent population size of Brachyramphus ...Arimitsu, Mayumi L.; Piatt, John F.; Romano, Marc D.; Madison, E.N.; Conaway, Jeffrey S.
Geomorphology and river dynamics of the lower Copper River, Alaska
Located in south-central Alaska, the Copper River drains an area of more than 24,000 square miles. The average annual flow of the river near its mouth is 63,600 cubic feet per second, but is highly variable between winter and summer. In the winter, flow averages approximately 11,700 cubic feet per second, and in the summer, due to snowmelt,...Brabets, Timothy P.; Conaway, Jeffrey S.
Application of the multi-dimensional surface water modeling system at Bridge 339, Copper River Highway, Alaska
The Copper River Basin, the sixth largest watershed in Alaska, drains an area of 24,200 square miles. This large, glacier-fed river flows across a wide alluvial fan before it enters the Gulf of Alaska. Bridges along the Copper River Highway, which traverses the alluvial fan, have been impacted by channel migration. Due to a major channel change in...Brabets, Timothy P.; Conaway, Jeffrey S.
Bathymetric and hydraulic survey of the Matanuska River near Circle View Estates, Alaska
An acoustic Doppler current profiler interfaced with a differentially corrected global positioning system was used to map bathymetry and multi-dimensional velocities on the Matanuska River near Circle View Estates, Alaska. Data were collected along four spur dikes and a bend in the river during a period of active bank erosion. These data were...Conaway, Jeffrey S.
Hydraulic survey and scour assessment of Bridge 524, Tanana River at Big Delta, Alaska
Bathymetric and hydraulic data were collected August 26–28, 1996, on the Tanana River at Big Delta, Alaska, at the Richardson Highway bridge and Trans-Alaska Pipeline crossing. Erosion along the right (north) bank of the river between the bridge and the pipeline crossing prompted the data collection. A water-surface profile hydraulic model...Heinrichs, Thomas A.; Langley, Dustin E.; Burrows, Robert L.; Conaway, Jeffrey S.
Modeling surface-water flow and sediment mobility with the Multi-Dimensional Surface-Water Modeling System (MD_SWMS)
The Multi-Dimensional Surface-Water Modeling System (MD_SWMS) is a Graphical User Interface for surface-water flow and sediment-transport models. The capabilities of MD_SWMS for developing models include: importing raw topography and other ancillary data; building the numerical grid and defining initial and boundary conditions; running simulations...McDonald, Richard; Nelson, Jonathan; Kinzel, Paul; Conaway, Jeffrey S.
Application of acoustic doppler current profilers for measuring three-dimensional flow fields and as a surrogate measurement of bedload transport
Acoustic Doppler current profilers (ADCPs) have been in use in the riverine environment for nearly 20 years. Their application primarily has been focused on the measurement of streamflow discharge. ADCPs emit high-frequency sound pulses and receive reflected sound echoes from sediment particles in the water column. The Doppler shift between...Conaway, Jeffrey S.
