Components identified in the calculation tool include: % of catchment that is wetland, Internal flow distance (path length), growing degree days, % bare ground and thatch, Ground iregularity, % of AA that is flooded only seasonally, Annual water fluctuation range, Predominant depth class, % of water that is ponded, % of ponded water that is open, Width of vegetation zone within wetland, Flat shoreline extent, Interspersion of emergents & open water, Channel connection & outflow duration, Outflow confinement, Throughflow resistance, Internal gradient, Soil or sediment alteration within the assessment area. Benefit indicators: Degrated water upstream, Degraded water downstream, Wetland as a % of its contributing catchment area, Unvegetated surface in the contributing area, transport from upslope, % of AA without surface water, Annual water fluctuation range, Tributary channel, Vegetated buffer as % of perimeter, Buffer slope
