The red tide is an abnormal water environment phenomenon, which harshly effects economic growth, aquatic life, and human health. It characterizes a major ecological problem in the marine ecosystem universally. The process of red tide prevalence has been investigated for several years, and a lot of systems and approaches have been established. Though previous researches have efficiently explored the knowledge of the process involved in red tide development, the combined effect of the coastal riverfront water quality of different coastal areas on red tide development has not attained sufficient consideration. The study has examined the connection between red tides and pollution load from the coastal waterfront. The research assesses the water quality of the coastal river waterfront (Tamjin River) using Water Quality Analysis Simulation Program (WASP 8.1) and nutrient load discharged into the West Sea using LOADEST. Through long-term investigation of the study region, it was found that red tides only occur in the late summer season. By investigating all the nutrient's load, TN (Total Nitrogen) and Chl-a (Chlorophyll-a) shows significant impact on red tides to some extent. The result of this study reveals that the pollution load from the coastal waterfront is also one of the possible factors of red tide occurrence in coastal region of the South Sea near the Tamjin River delta.
