Assessment of the Maximum Permissible Load of Pollutant in an opened coastal zone using a water quality model: a case study in Hainan of China

Abstract

Abstract This study aims to estimate the maximum-permissible-loads of pollutant by means of water quality modelling, in order to maintain the concentrations of pollutions below prescribed water quality targets. Modelling of water quality used the Mike21 HD and ecolab modules, while the assessment of maximum-permissible-loads of pollution used the method of response factor coefficient. This research is descriptive quantitative parameters of COD. A scenario assessment was carried out by the flows from various point sources to understand the site-specific relationships between pollution sources and water quality conditions, as well as calculating the maximum-permissible-loads to determine the pollution point source discharge.
