Global Surface Area of Rivers and Streams Higher than Previously Thought[28-Jun-18] Hydrologist George Allen (Texas A&M University) and SWOT Hydrology Science Lead Tamlin Pavelsky (University of North Carolina at Chapel Hill) used a statistical model to determine that global river and stream surface area is about 45 percent greater than indicated by previous studies. The findings, published in the journal Science, may change our understanding of the importance of streams and rivers in exchanging greenhouse gases with the atmosphere.
Before the Flood: New NASA Study May Improve Future River-Observing Satellites[07-May-18] Floods are one of the most common and devastating of Earth's natural disasters. A new study at NASA's Jet Propulsion Laboratory analyzes what it would take for river-observing satellites, such as SWOT, to become powerful tools for predicting and mitigating flood impacts.
