Urbanisation process can have a positive impact in terms of socio economic development. However, urbanisation negatively impacts on the water environment in both quantitative and water qualitative terms. In terms of water qualititative, increase in anthropogenic activities within an urbanised area leads to the generation of high amounts of pollutant build up on the impervious surface and will be washed off during the storm event. The first flush phenomenon during wash off process is an important parameter in designing effective stormwater treatment. Therefore, in depth understanding of first flush behavior which are responsible for the accumulation and transport of various pollutants in the urban environment is important. The first flush behavior was investigated in urban residential area in Gold Coast, Australia and also a small catchment in higher learning institution in Johor, Malaysia. Several water quality parameters were tested such as Total Suspended Solids, Total Dissolved Solids, Total Nitrogen, Total Phosphorus and Zinc. The influence of catchment and rainfall characteristics on first flush behavior was investigated. Therefore, PROMETHEE and GAIA was adopted in order to achieve the objective. The results show that rainfall pattern and location of the pollutants source play an important role on first flush behavior.
