| Popis: | The aim of this study was to conduct a comparative evaluation of evapotranspiration (ET) rates for eight different mesocosm constructed wetlands (CWs), and the relationship with redox potential (EH). Inflow, outflow and EH were measured over 4 years in winter and summer campaigns as well as over 24 h on selected days in summer. Vegetation was the main design parameter which affected water loss in the wetlands (on average, ET in planted wetlands was 4 times higher than in unplanted ones), and Typha angustifolia was more active than Phragmites australis (mean daily ET – expressed as the average of ET rate measured every 2 h in selected days in summer – was 36.8 ± 2.3 mm d−1 and 23.0 ± 1.9 mm d−1 for hydroponic wetlands planted with cattail and common reed, respectively), although P. australis water use efficiency was lower. Positive relationships were found between ET and EH for planted wetlands. Cattail presented a stronger linear regression than common reed, demonstrating that ET and consequently redox conditions are plant species-dependent. |
