A Versatile Workflow for Building 3D Hydrogeological Models Combining Subsurface and Groundwater Flow Modelling: A Case Study from Southern Sardinia (Italy)

Water, Journal Year: 2025, Volume and Issue: 17(1), P. 126 - 126

Published: Jan. 5, 2025

This research project aims to develop a basin-scaled 3D hydrogeological model by using Petrel E&P (Petrel 2021©) as the basis for numerical groundwater flow developed with “ModelMuse”. A relevant aspect of is use 2021© geologic modelling tools in field applied hydrogeology improve details both and models, their predictive capabilities. The study area located South Sardinia (Campidano Plain), where previous studies were available. was digitising interpreting facies available borehole logs; grid subsequently created, including main surfaces performing geostatistical based on grain size percentages. Afterwards, an empiric formula, achieved from tests laboratory analyses, distribution obtain preliminary hydraulic conductivity values, calibrated during simulations. These simulations, under various head scenarios, established boundary conditions values needed determine balance area. probabilistic approach has produced highly detailed able adequately represent natural phenomena anthropic stresses places underground.

Predicting Soil Salinity Based on Soil/Water Extracts in a Semi-Arid Region of Morocco

Soil Systems, Journal Year: 2025, Volume and Issue: 9(1), P. 3 - 3

Published: Jan. 8, 2025

Soil salinity is a major constraint to soil health and crop productivity, especially in arid semi-arid regions. The most accurate measurement of considered be the electrical conductivity saturated extracts (ECe). Because this method labor-intensive, it unsuitable for routine analysis large sampling campaigns. This study aimed identify best models estimate based on ECe relation rapid (EC) soil/water (referred as S:W henceforward) extracts. We evaluated relationship between ECS:W extract ratios (1:1, 1:2, 1:5) salt-affected soils from Sehb El Masjoune region Morocco. 0.5 235 dS/m, determined by method. A total 125 samples, topsoil (0–15 cm) subsoil (15–30 with mainly fine medium textures, were analyzed using linear, logarithmic, second-order polynomial regression models. included all samples or grouped according texture (fine, medium) specific textural classes. mean values 2.6, 3.1, 7.9 times greater than EC 1:1, 1:5 extracts, respectively. Polynomial had predictive accuracy, R2 = 0.98, lowest root square error 10.6 10.7 dS/m 1:2. could represent non-linear relationships indicators, 80–170 range, where other typically underestimate salinity. These results confirm that advanced techniques are suitable predicting region. site-specific outperformed previously published models, because they consider spatial variability heterogeneity area explicitly. confirms importance calibrating local environmental conditions. Consequently, we can undertake assessments hundreds simple, extraction direct indicator extrapolate model. Our approach enables widespread needed land-use planning, irrigation management, selection landscapes.

Hydrogeological Parameters Identification in the Qingtongxia Irrigation Area Using Canal Stage Fluctuations

Water, Journal Year: 2025, Volume and Issue: 17(6), P. 861 - 861

Published: March 17, 2025

Accurate characterization of aquifer hydrogeological parameters is critical for sustainable groundwater resource management. Traditional methods such as pumping tests often assume homogeneity and require substantial resources, limiting their applicability large-scale heterogeneous systems. This study proposes a novel approach to estimate the spatial distribution hydraulic conductivity (T) specific storage (Ss) in Qingtongxia Irrigation Area, utilizing canal stage fluctuations natural stimuli. By analyzing high-frequency level responses from monitoring wells during irrigation channel operations, we employed Sequential Linear Estimator (SLE) method combined with tomography invert parameters. The results demonstrate that inverted aligns well lithological variations historical data, showing higher values southern alluvial fan lower northern plains. SLE effectively captured heterogeneity, RMSE correlation coefficients between test inversion improving 1.81 0.76 after excluding outliers. work highlights potential stimuli (e.g., irrigation-induced fluctuations) basin-scale parameter estimation, offering cost-effective alternative traditional methods. findings provide valuable insights modeling management arid regions intensive
