J. of GEOMATE.Numerical modeling of the spatial distribution of water quality in Singkarak Lake, Western Sumatra, Indonesia is conducted. Field measurement data are collected, including bathymetry, water level, current velocity, and water quality data. The measured parameters in the water quality survey are the total suspended sediment (TSS), chemical oxygen demand (COD), biochemical oxygen demand (BOD), dissolved oxygen (DO) and phosphate (P). The finite element model is implemented using a surface-water modeling system (SMS). The model includes flow, constituent, and sedimentation models. Validation of the flow model is achieved by matching the current and the water elevation between the model and the field data. The validation shows good agreement. The model is aimed at observing yearly water quality and sedimentation change at the lake. The results from the constituent model show that the Sumpur and Sumani Rivers are having the greatest effect on the water quality of the lake in its northern and southern regions, respectively. A bed change of around 30-40 cm per year is found at the inlets of both of these rivers. Overall, the model shows that the lake water is only suitable for irrigation or fishing hatchery, and not for drinking water, according to the criteria for water quality standards in the Indonesian government’s Regulation 82 of 2001.[/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,Singkarak Lake,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=”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/10.21660/2019.54.8145[/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]
