Numerical modeling was initially conducted on three different geoelectrical arrays.Item Restricted A GIS-based linear regression modeling approach to assess the impact of geologic rock types on groundwater recharge and its hydrological implication(Springer, 2019) Kehinde Anthony Mogaji; Hwee San LimIn this study, the efficacy of the linear regression modeling technique in the company of recharge rate-induced geophysical parameters was implemented through geographical information system to establish the essentiality of geology factor in recharge rate estimate and prediction.Item Restricted Trace metals geochemistry for health assessment coupled with adsorption remediation method for the groundwater of Lorong Serai 4, Hulu Langat, west coast of Peninsular Malaysia(Springer, 2020) Usman Abdullahi Usman; Ismail Yusoff; Muggundha Raoov; Jonathan HodgkinsonThe research study was carried out to evaluate trace metals (Pb, Cd, Se, Al, Mn, Cu, Zn, Fe, As, Ni, Cr, and Ag) concentrations in groundwater of Lorong Serai 4, Hulu Langat, Selangor, Malaysia. Additionally, the research study focused on determining non-carcinogenic and carcinogenic health risks, sources of the contaminants, and effective remediation methods.Item Open Access Assessments of seasonal groundwater recharge and discharge using environmental stable isotopes at Lower Muda River Basin, Malaysia(Springer, 2018) Mohd Khairul Nizar Shamsuddin; Wan Nor Azmin Sulaiman; Mohammad Firuz Ramli; Faradiella Mohd Kusin; Kamarudin SamudingAn accurate estimation of groundwater recharge is required to properly manage aquifers, especially for riverbank filtration method (RBF) purposes. The isotopes correlations and differences in different water bodies were studied to assess the sources of groundwater recharge and preliminary tools in understanding of the surface water and groundwater interactions in the Lower Muda River Basin.Item Open Access An overview of groundwater chemistry studies in Malaysia(Springer, 2015) Nura Umar Kura; Mohammad Firuz Ramli; Wan Nor Azmin Sulaiman; Shaharin Ibrahim; Ahmad Zaharin ArisIn this paper, numerous studies on groundwater in Malaysia were reviewed with the aim of evaluating past trends and the current status for discerning the sustainability of the water resources in the country.Item Restricted Groundwater and surface-water utilisation using a bank infiltration technique in Malaysia(Springer, 2014) Mohd Khairul Nizar Shamsuddin; Wan Nor Azmin Sulaiman; Saim Suratman; Mohamad Pauzi Zakaria; Kamarudin SamudingBank infiltration (BI) is one of the solutions to providing raw water for public supply in tropical countries. This study in Malaysia explores the use of BI to supplement a polluted surface-water resource with groundwater. Three major factors were investigated: (1) contribution of surface water through BI to the resulting abstraction, (2) input of local groundwater, and (3) water-quality characteristics of the resulting water supply.Item Restricted Understanding of groundwater salinity using statistical modeling in a small tropical island, East Malaysia(Springer, 2011) Sarva Mangala Praveena; Mohd Harun Abdullah; Kawi Bidin; Ahmad Zaharin ArisThis paper presents an understanding of groundwater salinity by identification of effective factors using chemometric methods (cluster analysis and multiple linear regressions) in Manukan Island, Sabah.

Z. Aris; M. H. Abdullah; A. Ahmed; K. K. WoongFactor analysis was applied to the hydrochemical data set of Manukan Island in order to extract the principal factors corresponding to the different sources of variation in the hydrochemistry. The application of varimax rotation was to ensure the clear definition of the main sources of variation in the hydrochemistry.

The integrated methodology developed for this work provides the basis for a generic mineral characterization toolkit. Five main alluvial soil types have been defined in the upper layer of the lower Kelantan Basin, Malaysia: sand with low clay content, clay sand, sandy clay, mottled clay, and mud-sand.
