Special Issue Information

Dear Colleagues,

Aquifer characterization is essential for many groundwater-related research and applications, such as groundwater resource management, groundwater remediation, and the utilization of shallow geothermal energy. Over recent decades, new techniques for both the numerical modeling and field investigation of hydrogeological parameters have progressed due to increased computational power and modern sensing technology. These techniques have enhanced the precision of aquifer characterization, providing more comprehensive hydrogeological property data and a better understanding of the hydrodynamic behaviors of groundwater systems.

This Special Issue aims to present advanced methods and techniques applied to hydrodynamic aquifer characterization. Developments in analytical solutions, numerical modeling, laboratory experiments, field investigations, and machine learning-based applications are the main components of this Special Issue. Research on these subjects helps to improve the understanding of hydrodynamic aquifer characteristics and thus the accuracy of calculations of groundwater flow and transport-related behaviors.

We encourage the submission of papers related to dynamic aquifer characterization, inverse problems in subsurface hydrology, hydraulics, thermal and solute tracer tomography, hydrogeophysics, numerical model development, field investigations and applications, aquifer heterogeneity at various scales, and multidisciplinary studies. We also welcome studies that incorporate advanced computational tools, such as machine learning algorithms and computer clusters, for calibrating big data obtained from field investigations or high-resolution laboratory experiments.

The external water pressure and seepage quantity are crucial factors in tunnel construction design, especially under complex geological conditions. Both analytical solutions and numerical simulations can be used to calculate the external water pressure in a shallow circular cross-section tunnel. Analytical formulas are usually derived based on homogeneous surrounding rock, which seems somehow unrealistic. In reality, the engineering geological conditions are complex and the surrounding rock is heterogeneous. Therefore, the results of analytical formulas may deviate from the actual results. This study takes the No. 1 shallow-buried tunnel in the north bank of the Xiaolangdi irrigation area as its research background. Based on heterogeneous and anisotropic analyses, the horizontal permeability, the vertical permeability, the parameters of the lining and grouting circle, and the position head are the main factors affecting the stability of the external water pressure. The result shows that the external water pressure increases as the ratio of the horizontal permeability coefficient to the vertical permeability coefficient increases. Moreover, when a grouting ring is used to block the water, the lining is guaranteed to have a certain degree of permeability, which helps to better achieve the purpose of reducing the external water pressure.
