Wonnapha Beach's environmental conditions
The research, " The Effects of Seasons on Water Quality Changes at Wonnapha Beach”, aims to study the changes in seawater quality during different seasons and analyze the relationship between rainfall and coastal water quality. Seawater samples were collected from Wonnapha Beach. According to the observation of seawater discoloration in July 2024, measurements of temperature, salinity, pH, dissolved oxygen (DO), and water transparency were taken, with supporting data from The Institute of Marine Science, Burapha University and Thai Meteorological Department (TMD). The study found that seasons significantly affect seawater quality, with water quality ranging from poor to fair during the summer, while it is fair to good during the rainy and winter seasons. The study found that increased rainfall leads to a decrease in salinity and DO levels due to the transport of sediment and nutrients from land-based sources to the sea. This promotes plankton growth and may be the cause of seawater discoloration, which could be related to climate change or global warming.
