DESIGN OPTIMIZATION FOR ENHANCED POLLUTANT REMOVAL EFFICIENCY OF BIORETENTION CELLS

摘要

Consulting engineers, conservation authorities, and municipalities are looking for methods of storm water management control that not only restore pre-development hydrological cycles, but also offer the benefit of runoff quality treatment. As a result, Low Impact Development (LID) approaches, which are often applied at the source, have been gaining in popularity. The objective of this research is to develop guidance for the design of bioretention cells for runoff water quality treatment, evaluating bioretention cells' ability to perform such treatment function through modelling. A number of different modelling tools have been developed to simulate the performance of bioretention cells. These models are utilized to aid in the analysis of how bioretention cell design and layout affect the runoff treatment, for the purpose of providing engineering guidance on the optimal design of bioretention cells for stormwater runoff quality enhancements.
