Temporal and Spatial Analysis of Water Quality Data Observed in Lower Watershed of Nam River Dam
2013
Abstract Despite the Implementation of TMDL, the water quality in lower watershed of Nam river dam has worsened continuously since2005. Multifarious pollution sources such as cities and industrial districts are scattered around it. Nam river downstream bed slopeis very gentle towards the downstream water flow of slows it down even more, depending on the water quality deterioration isaccelerated eutrophication occurs. In this study, Nam River targets the mainstream by observation station looking at the status ofwater quality, water quality temporal and spatial characteristics of each analyzed station by station. The chemical and physicalwater quality in phytoplankton(Chl-a) to assess the impact on growth correlation analysis and multivariate analysis was per-formed. This section focused on the Nam River mainstream considering the temporal and spatial characteristics attributable to ana-lyze water quality target for water quality management to help achieve the aims.Key words : Water Quality, Discharge, Nam River watershed, Multivariate analysis, Pearson correlation coefficient, TMDL
