Watersheds, ecoregions and hydrologic units: the appropriate use of each for research and environmental management decisions

Informally Refereed

Abstract

It has long been recognized that conditions at a point on a stream are highly dependent on conditions upgradient within the topographic watershed. The hydrologic unit (HU) system has provided a useful set of nationally consistent, hydrologically based polygons that has allowed for the generalization and tabulation of various conditions within the stream and its valley.
