Abstract
The outcomes from two case studies which investigated the role of catchment and rainfall characteristics in influencing stormwater quality are presented in this Chapter. The case study which investigated the role of rainfall characteristics provides an innovative approach to classify natural rainfall events into three different types in the context of water quality. The proposed approach is in contrast to conventional approaches where rainfall events are classified solely based on quantity. The second case study confirmed the important role played by catchment characteristics such as urban form and impervious area layout in influencing pollutant wash-off. Therefore, the common practice of only considering land use and impervious area fraction to represent catchment characteristics can be questionable. Use of additional parameters in stormwater quality modeling enables more accurate accounting of the characteristics of urban catchments.
