ESD’s Rohit Salve, Daniella Rempe, and Bill Dietrich use various
measurement systems to document soil and rock moisture dynamics within a
4000 m2 zero-order basin in which all runoff occurs through
weathered argillite. Various field studies have concluded that shallow
groundwater in weathered bedrock underlying hillslopes can contribute
to both base and stormflow and thus dominate runoff.
