Groundwater resources assessment using numerical model: A case study in low-lying coastal area
Praveena, S. M. & Aris, A. Z.
Abstract
The impacts of climate change and human pressure in groundwater have been greatest threats facing
small islands. This paper represents a case study of groundwater responses towards the climate change and human
pressures in Manukan Island Malaysia. SEAWAT-2000 was used for the simulations of groundwater response in study
area. Simulations of six scenarios representing climate change and human pressures showed changes in hydraulic heads
and chloride concentrations. Reduction in pumping rate and an increase in recharge rate can alter the bad effects of
overdrafts in Manukan Island. In general, reduction in pumping rate and an increase in recharge rate are capable to
restore and protect the groundwater resources in Manukan Island. Thus, for groundwater management options in
Manukan Island, scenario 2 is capable to lessen the seawater intrusion into the aquifer and sustain water resources on
a long-term basis. The selection of scenario 6 is the preeminent option during wet season. The output of this study
provides a foundation which can be used in other small islands of similar hydrogeological condition for the purpose of
groundwater resources protection.
