Research ArticleOpen accessEvery word in the titleSpatio-Temporal Anomaly Detection in Groundwater Electrical Conductivity Using a Hybrid Framework of Isolation Forest and AutoencoderEunji Lee, Seunghyun Lim, Seojun Lee, Abhijit DebnathMonitoring groundwater quality is vital for environmental safety and resource sustainability. This study combines Isolation Forest and Autoencoder models to detect anomalies in Electrical Conductivity (EC) and temperature, using monthly data collected in South Korea between 2006 and 2023. Linear regression and the Mann-Kendall test reveal a weak, episodic downward EC trend. Seasonal decomposition indicates annual cyclicality, while residual analysis … …Journal of Computer Science, Vol. 22, Issue 1 · 14 Feb 2026 · 1,918 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEstimation of Natural and Artificial Recharge of Shahreza Plain Groundwater in Isfahan Using CRD and Hantush ModelsMohsen Nekooei, Jahangir Abedi Koupai, Saeid Eslamian et al.Cumulative Rainfall Departure model (CRD) is widely used for estimation of ground natural recharge. This model is based on the groundwater balance and it requires random parameters. Moreover, an increase in the static level under artificial recharge facility is simulated using diffusion equations. Since Shahreza Plain is located in an arid and semi-arid area and given that rainfall is the … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 17 Jun 2020 · 6,797 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleWater Resource Evaluation and Identifying Groundwater Potential Zones in Arid area using Remote Sensing and Geographic Information SystemM.M. Kamruzzaman, Saad Awadh Alanazi, Madallah Alruwaili et al.Groundwater resource is the main conventional source of fresh water all over the world. However, recent revelations indicated that the shortage of water resources remains the main challenge for the arid areas. In this regard, identifying groundwater potential zones or areas can help to improve the availability of fresh water and effective management of groundwater in arid areas. This work … …Journal of Computer Science, Vol. 16, Issue 3 · 3 Mar 2020 · 8,870 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGroundwater Quality Assessment of Three Zonal Regions in the Sunyani MunicipalityKwabena Antwi Kusi, Samuel Wiafe, Patrick Akaribila NsoniniThis project aimed at assessing the variation of ground water quality (physical, chemical and bacteriological parameters) in relation to the WHO standards from fifteen (15) randomly selected ground water sources in three (3) zones namely Abesim, Baakoniaba/Berlin-Top and New-Dormaa in the Sunyani Municipality. Groundwater samples were collected from five sampling points in each zone to determine the quality of the … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 1 · 11 Jan 2020 · 7,311 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUsing Permeable Reactive Barriers to Remediate Heavy Metal-Contaminated Groundwater through a Laboratory Column ExperimentSomean Yin, Gemunu Herath, Sokchhay Heng, Senajith KalpageRecently, groundwater sources are being polluted by various activities such as agriculture, livestock, decentralized wastewater treatment systems and acid rain. Groundwater can also be polluted by landfill leachate, sewage, mine tailings, non-engineered deep well disposal of liquid waste and seepage from industrial waste lagoons. There are many studies reported contaminated groundwater remediation using Permeable Reactive Barrier systems (PRBs) and many … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 12 Mar 2017 · 8,761 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleContamination Risk Evaluation of Groundwater in the Canton of Portoviejo-Ecuador, using Susceptibility Index and two Intrinsic Vulnerability ModelsSuhail SharadqahThe present study aims to investigate the applicability of DRASTIC, GOD and SI models in evaluating the groundwater vulnerability and risk of contamination in the Canton of Portoviejo, Ecuador. The groundwater vulnerability to contamination has been evaluated using DRASTIC and GOD models. Both models were able to classify the study area into different sectors of variable vulnerability. The coincidence of … …American Journal of Environmental Sciences, Vol. 13, Issue 1 · 11 Feb 2017 · 7,511 accessesView PDFCite
