The objective of this research is to understand the association between river and groundwater, and the water quality profile. Field measurements ware taken from 65 stations from Bogor to Jakarta. Water level, temperature, pH, and TDS were measured to build the water flow map and hydrochemical profile. Small-scale geoelectrical survey was conducted at five locations to capture the aquifer’s geometry. We identified three types of stream relationships between river and groundwater: effluent from Bogor to Katulampa (Segment 1), perched at the University of Indonesia (UI) area (Segment 2), and influent from UI to Muara (Segment 3), with low gradient from <0.1 to 0.3. The temperature profile of river and groundwater shows similar pattern as well as TDS profile. All similarities support close connection of river and groundwater. The increasing TDS towards downstream shows increasing enrichment and contamination. The erratic pattern of pH indicates chemical instability due to high contamination. This study highlights the benefit of understanding the hydrodynamic relationship between river water and groundwater. Such interaction triggers water quality exchange between both water bodies. Therefore, a similar study should also be done on other riverbanks in Indonesia to protect water quality.[/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]Chemical instability,Field measurement,Groundwater interaction,Hydrochemicals,Quality profile,Similar pattern,Surface water interaction,Temperature profiles[/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]Hydrochemistry Ciliwung River,Hydrodynamic,River–groundwater interaction[/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 Directorate General of Higher Education (DIKTI) with Competitive Grant Scheme Program 2006 financially supported the initiation of this work to 2007.
