| Abstract | The Chao Phraya River flows from the Northern Valleys through the central plain into the Gulf of Thailand. The lower reach of the Chao Phraya River is situated Bangkok City, is the river estuary, and is therefore subjected to tidal fluctuations. The river at present is polluted principally due to wastewater loading from klongs, direct discharging from factories and domestic wastewater. In this study, water quality status are analyzed and presented in the Chao Phraya River. Analytical solution of one-dimension dispersion for BOD profile and Dissolved Oxygen Sag have been applied and calibrated using measured data of the Chao Phraya River. Two different mathematical models namely one-dimension dispersion analytical model and BOD-DO finite difference model are applied to simulate the BODDO processes and to predict water quality of the Chao Phraya River in the future. Calibration for determination of their main coefficients and validation of the models are carried out in terms of water quality parameters BOD and DO on the collected data. The result of this study shows that BOD will reach its maximum value at 50 km from the river mouth and has a tendency of increasing in future. The dissolved oxygen (DO) sag curve will fall below 2 mg/l and will extend upstream from a point 50km. The result can meet the basic requirements for river water quality management and prediction of river water quality. iii |
