Eagle Creek at Zionsville, IN downstream of gage

In the aftermath of the 2018 Carr Fire, northern California, sediment has eroded from burned hillslopes and accumulated in some areas of Whiskeytown Lake. A recent sediment deposit is shown here in the Whiskey Creek section of the lake.

Zooming in even closer, an HVO scientist captured this image of the water on the floor of the crater during today's overflight. For more information, please read "Water or no water: that is (or was) the question"—HVO's Aug.

The sensor mounted on the drone is called the Qcam and is a Doppler radar sensor providing velocity from a hovering position above the river. USGS hydrologic technician (left) aboard a USGS John Boat mounted with Acoustic Doppler Current Profiler observes the Qcam conducting a measurement.

Kīlauea Volcano’s 2018 lower East Rift Zone eruption was monitored around the clock by field crews of Hawaiian Volcano Observatory and other USGS scientists for three months, starting with the first fissure that erupted in Leilani Estates on May 3, 2018.

USGS hydrographers collect tens of thousands of streamflow measurements every year. In-water work by personnel is one of the most dangerous aspects of USGS hydrologic studies, especially during high-flow conditions. In May 2019, USGS continued testing of a light-weight, self-contained ground-penetrating radar (GPR) system that can be mounted on a small drone.

The USGS, in cooperative research and development with GuidelineGEO, tested an 80 GHz self contained ground penetrating radar unit on a DJI Matrice 600 hexcopter (left). This platform was tested for flight performance and for measurement of river channel cross-sectional area as well as river water depth and river width.
