“It may seem as though a great deal is knownabout how, and from where, water gets from rainfall through hillslopes into streams, at least for some areas. There are, however, still major difficulties when we try either to particularize or generalize from our present knowledge”

Andy Pearce, 1990(Water Resources Research, p. 3046)
