Thank you Lancaster Liederkranz!

In the Alps, there are karst areas where plentiful precipitation soaks right in. This water flows through underground passages to important springs in the valleys below. Except for a few caves, these groundwater conduits are un-mapped. We are testing remote sensing methods for locating them. This will aid land use and water withdrawal planning to protect this critical resource from threats posed by (e.g.) increased development and climate change.
