Due to overcapacity, the current airport of Yogyakarta is going to be replaced with a new one,
which is located in Wates coastal area, Kulon Progo District, Yogyakarta Special Province, Indonesia. One of
the consequences of the development of the new airport is groundwater abstraction due to the airport’s needs
and related supporting activities. An excessive withdrawal of groundwater in the new airport will potentially
change the system and the pattern of groundwater flow. Therefore, groundwater modeling should be done to
predict the impact of groundwater abstraction in this area. MODFLOW code is used to simulate the
groundwater flow and the impact of groundwater pumping in the Wates coastal aquifer. The model is
calibrated using water level data from 40 wells in the research area. The results show that the calculated
values are fit to the measured data, which indicates that the model is reliable. The effects of groundwater
pumping on water table and seawater intrusion are investigated using a calibrated model. The results show
that the pumping scenario from the airport area causes the groundwater level to drop 0.75 m and seawater
intrusion inland to increase around 100 m.
