Groundwater - Surface Water Interaction Modeling in The Mampang Sub-Watershed
Keywords:
groundwater, Mampang Sub-watershed, SWAT, SWAT-MODFLOWAbstract
Groundwater - surface water around the banks of rivers/streams has an inseparable relationship. The interaction of the two impacts groundwater–surface water patterns in terms of quantity and quality of water. The research location is in the Mampang sub-watershed, part of the Krukut watershed area; the Krukut watershed is one of the major rivers in Jakarta. This research is to analyze the Ground Surface Water Exchange Rates (GSWER) with the aim of knowing the interaction of groundwater-surface water in the Mampang Sub-watershed. The research method consisted of collecting primary data and secondary data, SWAT simulation, SWAT-MODFLOW simulation, and GSWER value analysis. The results of the SWAT delineation of the Mampang sub-watershed with 21 sub-basins. The GSWER value for the rainy season, selected in April 2022, is the highest for the effluent system (gaining), worth - 223 m3/day, and the highest influent system (losing), is 305 m3/day. As for the dry season, August 2022 was chosen to be the highest for the gaining stream with a value of -83 m3/day and for the losing stream with a maximum value of 62 m3/day.
