J. of GEOMATE.This research of the Segara Anakan Estuary, Java Island, Indonesia, is carried out with the aim of developing a salinity intrusion model and investigating the adaptation scheme to mitigate the impact of sea level rise. The study includes topography, water level and current velocity field data acquisition to provide the required information for modeling. The bathymetry data are obtained from secondary data. The model uses the Surface-water Modeling System (SMS) developed by the US Army Corps of Engineers. The flow model within the SMS (RMA2 module) results in current velocity distribution in the domain, which is validated by field data. The validated flow model is developed into a water quality model (RMA4 module). It is found that the current velocity and salinity trend is highly correlated with Citanduy River discharge, which at the lowest value, the tide is able to propagate over 10 km into the Citanduy River. The simulation period is until 2050, in which the results show a sea level rise of 23.2 cm (referred to 2018). The model also shows that the saline water moves farther inland in 2050, impacting a salinity increase of ~0.5-2.5 ppt along the Citanduy River. In 2050, with check dam protection, an area of ~16.16 km from the mouth of the Citanduy River is only able to yield 75% productivity from October to December. The top elevation of the check dam becomes the determining point for mitigation.[/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]Numerical modeling,Salinity,Sea Level Rise,Segara Anakan Estuary[/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]The authors would like to thank the Asahi Glass Foundation for funding this research.[/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/10.21660/2019.53.05655[/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]
