In many case, mostly, pollutant brings a negative effect to the environment. It comes to the environment in many ways. This paper would be modelled a point source pollution in river in one dimensional numerical modelling to orient hydrological model by using explicit and implicit scheme. In the end, the concentration and spreadness in the river would be known. It would be modelled in three case condition which is has the same initial and boundary condition. Those cases give a different value of velocity of river and reaction term per day. The point source pollution located one of third of the river length. From the general form of the convective diffusion, this numerical modelling neglected the area because it assumed that the area is linear.To determine the constant of α, β, γ variables can be simplified in to the matrixsimultaneous equations. The output gives the graph time and concentration. This paper brings the similar result between hypothesis and the numerical modelling.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Convective diffusion,Explicit and implicit schemes,Gamma variables,Hydrological modeling,Initial and boundary conditions,Point source pollution,Pollutant distribution,Value of velocity[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Estuarine,Nutrient,Point source pollutant,River basin[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
