This paper reports the evaluation of the hydraulics of two constructed wetland (cw,) plants located in Apulia (the South Eastern Italy region characterized by semi and climate conditions). These fields were planted with Phragmites australis hydrophytes and are supplied with local secondary wastewater municipal treatment plant effluent. Each plant-Kickuth Root-Zone method based-covers an area of approx. 2,000 m(2). The evapotranspiration phenomenon has been evaluated within perforated tubes fixed to the field bottom and very high values - up to 40 mm/d - were found. Hydraulic conductivity has been, evaluated by in situ measurements at different field points. Hydraulic gradients and the piezometric curve within the field are also reported.

Abstract
This paper reports the evaluation of the hydraulics of two constructed wetland (cw,) plants located in Apulia (the South Eastern Italy region characterized by semi and climate conditions). These fields were planted with Phragmites australis hydrophytes and are supplied with local secondary wastewater municipal treatment plant effluent. Each plant-Kickuth Root-Zone method based-covers an area of approx. 2,000 m(2). The evapotranspiration phenomenon has been evaluated within perforated tubes fixed to the field bottom and very high values - up to 40 mm/d - were found. Hydraulic conductivity has been, evaluated by in situ measurements at different field points. Hydraulic gradients and the piezometric curve within the field are also reported.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
