“…The groundwater potential is quantitatively determined by the aquifer system model, both from the permeability value, rock porosity value, and fluid properties [9,10]. The potential for groundwater reserves stored in aquifers is primarily determined by the physical properties of the rocks that make up the aquifer [2]. This study determined the potential quantitative level of depressed groundwater for drinking water needs at the study site based on the optimum discharge (Qopt) of SD-DTW-DY wells.…”

One of the government’s efforts towards post-disaster reconstruction in 2018 at Central Sulawesi, especially in Palu City, is to build a Phase IA Duyu Permanent Occupancy. This study aims to determine the potential for confine aquifer based on the aquifer characteristics for freshwater—analysis of aquifer characteristics based on survey results, pumping test data, and hydrochemical parameters. The results showed that the quantitative potential of confine aquifer based on SD-DTW-DY well data was in the medium to high potential class in the Pz3.D0.T0.Qs0.Q0.M1 units, with the distribution of aquifer characteristic values: permeability (K) 53.09 m/day, the piezometric depth is 12.15 m from ground level, the aquifer thickness is 76.32 m, and debit (Q) is 9.50 l/second. Spatially the distribution of aquifers in denudational hills and alluvial plains at the Pakuli Formation with SND-GRV and GRA-DIO lithology. The results of the hydrochemical quality are good quality classes, include: TDS 182.0 mg/l, pH 8.3, Fe 0.00 mg/l, Mn 0.00 mg/l, Cl 11.70 mg /l, SO4 12.90 mg/l, NO3 0.00 mg/l, and NO2 0.18 mg/l. Based on the results of the data analysis, the characteristics of the aquifer in the Duyu permanent occupancy area are classified as medium productive aquifers.

“…Many hydrogeologists have conducted investigations and studies at this site, for example, analyzing the vulnerability of groundwater in Shijiazhuang City to high-intensity groundwater exploitation using a transient flow pumping test and numerical model inversion. Cheng et al [21] suggested that the study site is in a hydrogeological unit with pebble gravel sand interbedded with sub-clay and that the hydraulic conductivity is 100-400 m/d. In a study of sustainable groundwater management policies in typical agricultural irrigation areas in Shijiazhuang City, the hydraulic conductivity and specific yield were reported to be 120-150 m/d and 0.13-0.14, respectively [22].…”

Aquifer diffusivity is a basic physical parameter used in hydrogeological calculations and is important for the evaluation and rational utilization of water resources, pollution prevention, and wetland protection. In this study, with the assumptions of aquifer isotropy, i.e., no vertical flow and constant saturated aquifer thickness, by using the Fourier transform and convolution theorem, a 1D analytical solution of the phase spectrum for an unconfined aquifer system was derived, which subsequently led to a phase spectrum solution for aquifer diffusivity. To test the efficacy, the proposed method was applied to a study site in the middle reach of the Hutuo River in the North China Plain. The estimated aquifer diffusivity ranged from 1.9 × 103 to 4.9 × 104 m2/d, with a mean of 2.2 × 104 m2/d, which was consistent with the results obtained using power spectral analysis, pumping tests, and inverse numerical models. The phase spectral approach proposed in this paper can estimate the aquifer properties on a larger scale. If long time series of hydraulic heads are available, it can estimate hydrogeological parameters accurately and quickly. Considering the similarity of the linearized governing equations, it can also be applied to the river–aquifer system and the confined aquifer system.

“…In order to address the limitations of the DRASTIC-O model and integrate the DRASTIC-AHP, PPI, and DRASTIC-LU, a Composite Groundwater Vulnerability Model was developed, which accounts for both natural and human sources of groundwater contamination (Dumedah et al, 2021). To understand groundwater vulnerability and its changes, mean residence times (MRTs) can be combined with the chemical characteristics of groundwater (Cheng et al, 2021). In a study, GIS-based groundwater vulnerability assessment indices including DRASTIC, SINTACS, and GODS to assess the groundwater vulnerability levels and proposed a novel hybrid framework SWARA-PSO-GA in which The DRASTIC weighting system is optimized using PSO-GA (Particle Swarm Optimization-Genetic Algorithm) optimization algorithm to evaluate the vulnerability of their study area .…”

One of the most important and perilous groundwater contaminants is nitrate, which is considered a potential environmental risk in Iran and an international issue globally. The study area is the Karaj uncon ned aquifer, Central Iran, subjected to quantity and quality hazards due to unbalanced urban, industrial, and agricultural developments. Evaluation of the vulnerability condition of this aquifer against nitrate as the Contamination index is essential since the most amount of consumption water in the area is provided from groundwater. The study aims to detect vulnerable zones of the Karaj aquifer using DRASTIC + L and Modi ed VEBHAT vulnerability models. The weighting of the parameters has been performed employing the recent Multiple-Criteria Decision-Making (MCDM) methods, including Stepwise Weight Assessment Ratio Analysis (SWARA) and Best Worst Method (BWM). The results demonstrated that the most vulnerability had occurred from the east to the south of the aquifer (high to super-critical), including urban and residential areas, regarding both the vulnerability models' plots. The plots of the two methods are similar and did not exhibit considerable differences. The Modi ed VEBHAT has more certainty than the DRASTIC + L and has optimized and improved the DRASTIC + L model because the most vulnerable zone in the output plots of the Modi ed VEBHAT model is in the east of the aquifer, which has good agreement with the nitrate contaminant mass with the highest concentration.
