Songkhla lagoon is the largest lagoonal water resource in Thailand and Southeast Asia. The lagoon is a combined freshwater and estuarine complex of high productivity which represents an extraordinary combination of environmental resources believed to be unique in the region. Climate change, as a response to increased greenhouse gases in the Earth’s atmosphere, is now a widely accepted phenomenon. Sea level rise, temperature, precipitation, and storminess are expected to change significantly with global climate change and to impact coastal lagoons. The nature and magnitude of these impacts are still not very clear. The general objective of the research is to determine the climate change impacts on mixing and circulation at Songkhla lagoon, Thailand. To archive this objective the lagoon was be modeled with Delft 3D, a model developed by Deltares. After the verification with the available data for the region, different scenarios were created to represent the possible changes in mean sea level and riverflow due to global warming. Then, these results were compared to the current conditions to determine the main changes in mixing and circulation in this coastal lagoon. The results suggest an increase in water velocities of the inlet in future scenarios and a decrease of flushing time. Salinity and stratification showed more complex changes in futures scenarios.
