Plastic Waste
September 11, 2017

Microplastics in the environment are of increasing concern among resource managers and ecologists. With global production of plastic topping 300 million metric tons in 2015, research in fresh and marine waters throughout the world has implicated urban runoff, wastewater treatment effluent, and litter breakdown as major sources of microbeads and synthetic pieces and fibers that are slow to...

Aquatic Systems Branch scientists analyze rings of riparian trees relating tree growth and establishment to historical flow. We then use the tree rings to reconstruct the flow in past centuries. Flow reconstructions discover the frequency and magnitude of past droughts and floods—information that is essential for management of rivers and water supplies. We...

Storage filters upland suspended sediment signals delivered from watersheds

Climate change, tectonics, and humans create long- and short-term temporal variations in the supply of suspended sediment to rivers. These signals, generated in upland erosional areas, are filtered by alluvial storage before reaching the basin outlet. We quantified this filter using a random walk model driven by sediment budget data, a power-law...
