Wetlands subsurface flow

Point and nonpoint sources, precipitation, and biological N fixation are the major inputs to wetlands, whereas N losses from wetlands include biotic (denitrification) and abiotic (volatilization) reactions and surface/subsurface flows. Wetlands often function as effective reservoirs of N. [Pg.322]

Constructed wetlands (CWs) can promote removal of PhCs through a number of different mechanisms, including photolysis, plant uptake, microbial degradation and sorption to the soil. The main benefits of horizontal and vertical subsurface flow systems are the existence of aerobic, anaerobic and anoxic redox conditions in proximity to plant rhizomes this provides an ideal environment for reducing...

The hydroperiod of wetlands is dependent on flow, depth, frequency, duration (the amount of time wetlands are in standing water), seasonality, and frequency of flooding (average number of times wetlands are flooded or saturated). Thus, the hydroperiod of a wetland includes all aspects of water budget (rainfall, evapotranspiration, and subsurface and surface flow) irrespective of the source of the water. The following qualitative definitions have been presented for wetland hydroperiods in tidal and nontidal wetlands (Cowardin et al., 1979 summarized by Mitsch and Gosselink, 2000). [Pg.34]
