Paper Title
Organic Pollutants And Heavy Metals Transport In The Lower Chaophraya Basin Using Swat Model

Abstract
The organic pollutants and heavy metals contaminated in the river have been increasingly concerned due to environmental impact, and their high toxicity effects on human health. The raw water that is required for the water supply system in Bangkok generally comes from the Chao Phraya River. In case of the water quality in the Chao Phraya River is poor due to high concentrations of those contaminants affect to the water treatment cost will be increased leading to adversely effects on all water consumers. Water quality analysis in laboratory is expensive and taken much more time. The correct model assessment is worth way to evaluate water quality in the water body for reducing water sampling points. Model development for organic pollutants and heavy metals transport assessment in the Lower Chao Phraya River is important to predict environmental impact which may occurs in the future and helpful to prepare resolution of environmental impact immediately. The model can be guidelines for environmental sustainable management by the prediction. In this study using Soil and Water Assessment Tools (SWAT) version 2012 predict organic pollutants and heavy metals transportation. The calibration of model presented simulated values and measured values almost the same including average monthly flow rates, and water quality data. However, the model verification for long term has to update to data at that time such as land use changing, soil properties changing, and precise weather prediction. Keywords- Soil and Water Assessment Tools (SWAT), Organic pollutants, Heavy metals, Chao Phraya basin.
