Upl<strong>and</strong> – Any area that does not qualify as a wetl<strong>and</strong> because the associated<br />
hydrologic regime is not sufficiently wet to elicit development of vegetation, soils<br />
<strong>and</strong>/or hydrologic characteristics associated with wetl<strong>and</strong>s.<br />
<strong>Water</strong>shed – The total topographic region or area bounded peripherally by a<br />
divide <strong>and</strong> draining ultimately to a particular watercourse or body of water; also<br />
called catchment area, drainage area, <strong>and</strong> basin.<br />
Weighted Usable Area (WUA) – A component of PHABSIM which is an<br />
indicator of the net suitability of use of a given stream reach by a certain life<br />
stage of a certain species.<br />
Wetl<strong>and</strong>s – Those areas that are inundated or saturated by surface or<br />
groundwater at a frequency <strong>and</strong> duration sufficient to support, <strong>and</strong> that under<br />
normal circumstances do support a prevalence of vegetation typically adapted for<br />
life in saturated soil conditions. Wetl<strong>and</strong>s generally include swamps, marshes,<br />
bogs <strong>and</strong> similar areas.<br />
Wetl<strong>and</strong> Soils – A soil that has characteristics developed in a reducing<br />
atmosphere, which exists when periods of prolonged soil saturation results in<br />
anaerobic conditions.<br />
Wetl<strong>and</strong> Vegetation – The sum total of macrophytic plant life that occurs in<br />
areas where the frequency <strong>and</strong> duration of inundation or soil saturation produce<br />
permanently or periodically saturated soils of sufficient duration to exert a<br />
controlling influence on the plant species present.<br />
Wetted Perimeter – The cross-sectional distance along the stream bed <strong>and</strong><br />
banks that is in contact with water.<br />
Wetted Perimeter Inflection Point – A point on a curve relating wetted perimeter<br />
vs. discharge at which the slope of the line changes from convex to concave or<br />
vice versa.<br />
Woody Habitats – Any of the various living (e.g., exposed roots) or<br />
dead/decaying (e.g., snags) substrata composed of wood, usually originating<br />
from riparian vegetation that serve as habitation for various instream biota.<br />
