The Ribble River flowing through Preston in Lancashire, United Kingdom, 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 a heavily used public footpath." The trust is using survey results to reveal these hidden depths on interpretation boards, including digitally augmented reality and video media enabling visitors to explore the underwater world.
