The U.S. Geological Survey (USGS) and independent scientists gathered in Auburn, Maine, to evaluate the use of sensor-mounted unmanned aircraft systems (UAS) to gauge stream stage, velocity, bathymetry and discharge. The technology is being evaluated and modeled to determine whether it will support the fast, accurate and safe measurement of rivers, especially when they are flooded or contain floating trees,... read more

The Ribble River flowing through Preston in Lancashire, U.K., has hidden depths. “The challenge with rivers is that much of the beauty and interest is hidden from view beneath the surface,” said Jack Spees, CEO of the Ribble Rivers Trust. “To reveal this beauty, we undertook a bathymetric survey of a section with particularly interesting features that is adjacent to... read more
