Groundwater has become an important source of water to meet the increasing requirement for domestic, industrial, and agricultural needs. The study was formulated to assess the availability of groundwater resources in Selangor State, Malaysia. An integrated MIKE SHE and MIKE 11-based surface water–groundwater interaction model was developed to fulfill the study objectives. Model results illustrated that groundwater flows from the eastern part of the hilly region to the western part and ultimately discharges into the sea. The study also revealed that Sungai Langat, Sungai Klang, and Sungai Selangor receive water from groundwater and do not feed the groundwater. Approximate potential groundwater resources based on water balance study varies from 860–960 million liter per day (MLD), 630–690 MLD, 810–870 MLD to 630–690 MLD for Langat basin, Klang basin, Selangor basin, and Bernam basin, respectively. Impacts due to extreme dry condition showed that groundwater table declined about 0.5–3 m in most of the area. However, groundwater level for the major portion of Selangor State will drop to about 0–1 m for increased abstraction due to changed land-use pattern. Study findings may be used for a holistic and comprehensive management of groundwater resources for sustainable development in Selangor State, Malaysia.

地下水已成为满足家庭，工业和农业需求不断增长的重要水源。该研究旨在评估马来西亚雪兰莪州的地下水资源。为了实现研究目的，开发了基于MIKE SHE和MIKE 11的集成地表水-地下水相互作用模型。模型结果表明，地下水从丘陵地区的东部流向西部，并最终排入海洋。研究还显示，Sungai Langat，Sungai Klang和Sungai Selangor接受地下水中的水，不给地下水供水。根据水平衡研究得出的潜在潜在地下水资源，从每天860-9.6亿升（MLD），630-690 MLD，810-870 MLD到630-690 MLD，到Langat盆地，Klang盆地，雪兰莪盆地和伯南盆地。极端干旱条件造成的影响表明，大部分地区的地下水位下降了约0.5–3 m。然而，由于土地利用方式的改变，雪兰莪州大部分地区的地下水位将下降至约0-1m，以增加取水量。研究结果可用于马来西亚雪兰莪州的地下水资源的全面和综合管理，以实现可持续发展。
