| Abstract | Sustainable environmental development has become an important target for many countries. People do not only need higher living standards, but also a cleaner environment, which should be preserved for the next generations. Pattaya City in Thailand is one of the examples, which moves too quickly from being small fishing village to a big city with a high number of tourists. This fact triggers many problems including coastal pollution. Due to booming tourism and rapid economic development, the environment of Pattaya beach, especially water quality has been damaged. Nobody wants to swim at Pattaya beach due to combined sewer overflows along the beach. Reports from the Tourism Organization of Thailand have shown that the number of tourists is going down day by day, even though the new wastewater treatment plant has been in operation since November 2000. With the rapid development of computers, mathematical models are now widely used to simulate, analyze and predict various scenarios related to water and environment. Many studies have been conducted to simulate and evaluate water quality, using mathematical models. In this study, different models are used for each part of the water quality systems: catchment runoff and pipe flow are described by MOUSE™, water quality is simulated by MOUSE TRAP™ and processes in coastal areas are based on MIKE 21™. In addition, descriptions from historical records of input and output water quality from the wastewater treatment plant are used in the modeling system. So far, many case studies have been carried out by using models to simulate each part of the system. Flood in the urban area, pollution in receiving water, bad performance of WWTP are different problems and could be solved separately by different model. The present study develops a new concept for using model: i.e. application of integrated models to achieve a complete view on the problems, and to identify solution respect to the interaction between all the units in the system. Particularly, the models integrate the operation of the sewer system directly with the impact on receiving coastal water, and this provides a comprehensive overall view of the problems. Present sewer system of Pattaya City is modelled, water quality in the coastal area is calculated, records data of the WWTP is collected, in purpose to find out the impact effects of the wastewater treatment plant. The integrated model is also answer the question should people swim in the Pattaya beach or not, and when it's possible. Results from models show the picture of the problems in Pattaya beach. The whole system is integrated modeled, the interaction between them is simulated and some solutions to solve the problem are offered. In this study, the integrated concept was test to see if it applicable to apply, what is the key point when apply it, which condition can bring it up or shut it down. |
