| Abstract |
Despite the implementation of TMDL, the water quality in lower watershed of Nam river dam has worsened continuously since 2005. Multifarious pollution sources such as cities and industrial districts are scattered around it. Nam river downstream bed slope is very gentle towards the downstream water flow of slows it down even more, depending on the water quality deterioration is accelerated eutrophication occurs. In this study, the mainstream in lower watershed of Nam river dam region to target aquatic organic matter by phytoplankton growth contribution was evaluated by statistical analysis. And statistical evaluation of water quality and the accuracy of forecasting, model calibration and verification procedures by completing QUALKO2 it`s eutrophic phenomena that occur frequently in the dam outflow through scenarios predict an increase in water quality management plans to present the best should. |
