SIMULASI NUMERIK PADA ALIRAN AIR TANAH MENGGUNAKAN COLLOCATION FINITE ELEMENT METHOD

open access: yesE-Jurnal Matematika, 2018
This research presents a numerical simulation on groundwater flow using collocation finite element method (CFEM). Groundwater flow is known as the flow of water beneath the soil. Generally, groundwater flow is generated due to high hydraulic differences.

Investigating riparian groundwater flow close to a losing river using diurnal temperature oscillations at high vertical resolution [PDF]

open access: yesHydrology and Earth System Sciences, 2012
River-water infiltration is of high relevance for hyporheic and riparian groundwater ecology as well as for drinking water supply by river-bank filtration. Heat has become a popular natural tracer to estimate exchange rates between rivers and groundwater.
