      Capacity: A Case of Ganh Rai Bay, Vietnam.

AB  - Economic activities are constantly increasing in the southern key economic region 
      (SKER), especially in Ho Chi Minh City (HCMC), which leads to the influx of large 
      amounts of wastewater from this region into Ganh Rai Bay (GRB). The problem of 
      assessing the marine environmental carrying capacity (MECC) of coastal areas is 
      urgent, and the role of self-cleaning must be elucidated. Four typical pollution 
      parameters were selected: ammonium (NH(4)(+)), biological oxygen demand (BOD), 
      phosphate (PO(4)(3-)), and coliforms. The study aims to propose a framework to 
      assess the impact of the role of self-cleaning on MECC and to apply the proposed 
      framework to GRB as a case study. A series of models were used to simulate 
      hydrodynamics, and an advection-diffusion model with an ecological parameter set 
      was used for water quality modelling. The land-ocean interactions in the coastal 
      zone model were used to calculate the GRB and East Sea retention time. Finally, a 
      multiple linear regression model was used to clarify the relationship between the 
      MECC and self-cleaning factors. Calculation results show that the self-cleaning 
      factor increased the MECC(Ammonium) by 60.30% in the dry season and 22.75% in the 
      wet season; similar to MECC(BOD), MECC(Phosphate) increased by 5.26%, 0.21% (dry 
      season), and 11.04%, 0.72% (wet season), respectively. MECCC(Coliforms) in the 
      dry season increased by 14.83%; in the wet season, MECC(Coliforms) doubled. The 
      results provide medium-and long-term solutions to improve the water quality of 
      the GRB, especially the selection of activities that conserve the ecological 
      system and improve the self-cleaning capacity of the bay.
