All rights reserved.The reclamation projects in Jakarta are believed to have an impacts on the ecosystems in the surrounding area. Some of the potential changes are pattern of current, increasing the flow velocity and reduction of salinity in the river mouth. In this paper, hydrodynamic model is used to evaluate this statement. By preparing two scenarios represent the condition before and after the island were built, we can evaluate the differences in hydrodynamic condition in the area and study it’s effect to the mangroves live parameters. In this paper the hydrodynamic modelling has showed that there is no significant changes on water level, flow and salinity in the area that may harm the mangrove population. In addition to that earlier in the research some literatures have been discussed about many factors that infact responsible for mangrove disappearance that were presence long way before the islands are constructed. DELFT 3D program is used to modeled the hydrodynamic condition in the area. Natural aspects suchastidal, wind and river discharges are considered as input in the model to simulate the existing hydrodynamic condition. Later on in the model, artificial island is introduced as a solid land giving additional barrier to the flow which expected results in changes in flow direction and velocity. These changes are expected to influence a nutrient supply that can influence the mangrove’s growth.[/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][/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][/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]https://doi.org/10.1063/5.0016899[/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]
