This publication identifies the most important hydrologic and hydraulic elements which impression the functionality of stormwater caliber therapy structures resembling developed wetlands and bioretention basins. Mathematical relationships derived utilizing conceptual versions underpinned by means of primary hydraulic thought are awarded to foretell remedy functionality. the major highlights of the ebook will contain the identity of the linkages among influential hydrologic and hydraulic components for built wetlands and bioretention basins to help extra exact prediction of remedy functionality and powerful layout of those kinds of stormwater therapy structures. additionally, this ebook will show off an cutting edge technique for utilizing conceptual types to research stormwater remedy approach performance.

Example text

Storm water entering the constructed storm water wetland was pre-treated in the sedimentation pond prior to receiving further treatment in the wetland cells. A cell inlet control pit at the pond outlet ensures that the storm water enters the cells slowly, as high flow might disturb the cells and vegetation. Additionally, the maximum inflow rate that was allowed to enter the wetland cells was controlled by the bypass weir (see Fig. 6b). A 7 m wide bypass weir (broad crested) overflows when the water level is above its crest level and the storm water is discharged to the receiving water through the bypass channel without undergoing treatment.

The parameters generated by conceptual models for the bioretention basin were; volume treated, outflow peak, contributing area and volume retained, while the parameters generated for the constructed wetlands were average retention time, outflow peak, average outflow discharge, outflow volume and average depth of water. This showcases an innovative approach in using conceptual models to generate influential hydraulic factors, which in turn can be used to analyse storm water treatment system performance.

13) has been created to illustrate the modelling process and equations used in each step. 5 Percolation, Evapotranspiration and Direct Precipitation Percolation and evapotranspiration are two important factors influencing the constructed wetland water balance. A range of methods are available to estimate percolation rates. However, in the model developed, a constant percolation rate was used to ensure simplicity of the model. Initial percolation rate was selected based on the soil bed characteristics.
