Estimating sediment flux to Jamaica Bay, New York
Richard A. Cartwright, Amy E. Simonson
2019, Scientific Investigations Report 2019-5085
Tidal wetland loss in Jamaica Bay, New York, is well documented. Maintaining wetlands is important from an environmental and ecological perspective and because wetlands buffer coastal communities from storm damage. An estimate of suspended-sediment flux through Rockaway Inlet is needed to improve understanding of sediment dynamics in Jamaica Bay and...

Kelley Sterle, Wesley Kitlasten, Eric D. Morway, Richard G. Niswonger, Loretta Singletary
2019, Fact Sheet 19-10
What does climate change mean for snow-fed river basins?Climate change poses unique challenges in snow-fed river basins across the western United States because the majority of water supply originates as snow (Dettinger, Udall, & Georgakakos, 2015). In the Sierra Nevada, recent observations include changes in snow accumulation and snowmelt, and...

Off-channel waterbodies in the Middle Mississippi River: A pilot investigation
Molly Sobotka, John West
2019, Report
Off-channel and floodplain water bodies are important components of large river ecosystems while rare within the Middle Mississippi River. The lack of these habitats likely influences water quality, nutrient processing, and communities of organisms. In early 2016 a major flood event breached two levees south of Cape Girardeau, MO resulting...
