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, Nam River targets the mainstream by observation station looking at the status of water quality, water quality temporal and spatial characteristics of each analyzed station by station. The chemical and physical water quality in phytoplankton(Chl-a) to assess the impact on growth correlation analysis and multivariate analysis was performed. This section focused on the Nam River mainstream considering the temporal and spatial characteristics attributable to analyze water quality target for water quality management to help achieve the aims.
