The Sacramento and San Joaquin Rivers deliver half the amount of sediment they did 50 years ago to San Francisco Bay. Just as sea-level rise is accelerating, the demand for sediment is growing.
Daniel Nowacki
I'm a coastal oceanographer at the USGS Pacific Coastal and Marine Science Center in Santa Cruz, California.
I am interested in the sediment transport and morphology of coastal and riverine systems and how those processes and characteristics relate to coastal hazards.
My work is primarily rooted in observations of the physical world. I use these field observations, sometimes in conjunction with numerical model output, to answer questions about sediment transport, coastal vulnerability and resilience, and more. I also have interests in instrument design and development, and data standardization, distribution, and reproducibility.
Science and Products
Coastal Habitats in Puget Sound
A Pacific Northwest icon, Puget Sound is the second-largest estuary in the United States. Its unique geology, climate, and nutrient-rich waters produce and sustain biologically productive coastal habitats. These same natural characteristics also contribute to a high quality of life that has led to growth in human population and urbanization. This growth has played a role in degrading the Sound...
Climate impacts to Arctic coasts
The Arctic region is warming faster than anywhere else in the nation. Understanding the rates and causes of coastal change in Alaska is needed to identify and mitigate hazards that might affect people and animals that call Alaska home.
PS-CoSMoS: Puget Sound Coastal Storm Modeling System
The CoSMoS model is currently available for most of the California coast and is now being expanded to support the 4.5 million coastal residents of the Puget Sound region, with emphasis on the communities bordering the sound.
Using Video Imagery to Study Sediment Transport and Wave Dynamics: Nuvuk (Point Barrow)
Two coastal observing video cameras were installed atop a utility pole near the northernmost point of land in the United States, at Nuvuk (Point Barrow), Alaska. The cameras pointed northwest toward the Arctic Ocean and the boundary between the Chukchi and Beaufort Seas, and were used to observe and quantify coastal processes such as wave run-up, bluff erosion, movement of sandbars and ice floes...
Using Video Imagery to Study Wave Dynamics: Unalakleet
USGS scientists installed two video cameras atop a windmill tower in Unalakleet, Alaska, pointing westward over Norton Sound, to observe and quantify coastal processes such as wave run-up, development of rip channels, bluff erosion, and movement of sandbars and ice floes.
Using Jupyter Notebooks to tell data stories and create reproducible workflows
Increasingly, USGS scientists seek to share and collaborate while working on data and code. Furthermore, these scientists often require advanced computing resources. Jupyter Notebooks are one such tool for creating these workflows. The files are interactive, code “notebooks” which allow users to combine code and text in one document, enabling scientists to share the stories held within...
Estuarine Processes, Hazards, and Ecosystems
Estuarine processes, hazards, and ecosystems describes several interdisciplinary projects that aim to quantify and understand estuarine processes through observations and numerical modeling. Both the spatial and temporal scales of these mechanisms are important, and therefore require modern instrumentation and state-of-the-art hydrodynamic models. These projects are led from the U.S. Geological...
Estuarine Processes Model Development
We are developing new routines within the COAWST model framework to represent coupled bio-physical processes in estuarine and coastal regions. These include routines for marsh vulnerability to waves, estuarine biogeochemistry, and feedbacks between aquatic vegetation and hydrodynamics.

Video camera setup at Nuvuk, Alaska
Point Barrow, Alaska, or Nuvuk, is the northernmost point in the United States. USGS has set up video cameras, mounted to the pole shown here, to study sediment movement and wave dynamics along this dynamic coastline.

Rapid salt-marsh erosion in Grand Bay, Mississippi
Rapid salt-marsh erosion in Grand Bay, MississippiThis time-lapse video shows lateral erosion of a salt marsh in the Grand Bay National Estuarine Research Reserve, part of an embayment near the city of Pascagoula, Mississippi, on the US Gulf coast. Wave action over the course of 6.5 months led to about 1.5 meters of erosion.
