Modelling the Hydraulic Processes on Constructed Stormwater Wetland
Abstract: Constructed
stormwater wetlands are manmade, shallow, and extensively vegetated water
bodies which promote runoff volume and peak flow reduction, and also treat
stormwater runoff quality. Researchers have noted that treatment processes of
runoff in a constructed wetland are influenced by a range of hydraulic factors,
which can vary during a rainfall event, and their influence on treatment can
also vary as the event progresses. Variation in hydraulic factors during an
event can only be generated using a detailed modelling approach, which was
adopted in this research by developing a hydraulic conceptual model. The
developed model was calibrated using trial and error procedures by comparing
the model outflow with the measured field outflow data. The accuracy of the
developed model was analyzed using a well-known statistical analysis method
developed based on the regression analysis technique. The analysis results show
that the developed model is satisfactory.
