“…Percolation theory is an idea, a model, for solving a certain class of problems, and it has now become the classical theory for dealing with effects due to changes in the degree of association in disordered systems [18][19]. It describes the ability of a system composed of primitive phases or microstates to undergo macroscopic coupling, arguing that when the degree of mutual coupling of a phase or a state within the system increases to a percolation threshold, the system will undergo a sharp geometric phase transition and a sudden emergence of long-range coupling as a result.…”

In this paper, data mining is performed based on the directed percolation theory influence mining algorithm, analyzing the maximum influence node mining proportion threshold and calculating the maximum eigenvalue of the non-return matrix. The convergence conditions of the iterative process of immobile points are analyzed to obtain the percolation threshold of the information dissemination process of directed percolation, and the initial vector is selected among the node-associated features to form the iterative formula to mine the maximum percolation theoretical influence. According to the results, students' focus on craftsmanship has risen significantly, and the percentage of students who consider persistent concentration spirit important has increased to 75%. The directed percolation theory's craftsmanship spirit is crucial for developing students' vocational skills and comprehensive literacy.

“…Two papers address the topics of groundwater contamination and protection. Li et al (2019) [5] used the numerical model of density-dependent groundwater flow and solute transport to analyze the influence of tidal fluctuation and water curtain systems on the temporal-spatial variations in seawater intrusion in an island oil storage cavern in China. The results show that the operation of an underground water-sealed oil storage cavern in an island environment has a risk of inducing seawater intrusion.…”

Groundwater is an essential and vital water resource for drinking water production, agricultural irrigation, and industrial processes. The better understanding of physical and chemical processes in aquifers enables more reliable decisions and reduces the investments concerning water management. This Special Issue on “Water Flow, Solute and Heat Transfer in Groundwater” of Water focuses on the recent advances in groundwater dynamics. In this editorial, we introduce 12 high-quality papers that cover a wide range of issues on different aspects related to groundwater: protection from contamination, recharge, heat transfer, hydraulic parameters estimation, well hydraulics, microbial community, colloid transport, and mathematical models. By presenting this integrative volume, we aim to transfer knowledge to hydrologists, hydraulic engineers, and water resources planners who are engaged in the sustainable development of groundwater resources.

“…Compared to traditional land-based environments, the seepage field operation law of the underground oil depot system in island environments is significantly more complex, requiring careful consideration of issues such as seawater intrusion, hos in hydraulic conductivity, and tidal dynamics [18][19][20][21]. In addition, seawater intrusion will not only corrode the structure of the underground caverns (steel, concrete, etc.)…”

Underground water-sealed oil storage caverns constructed in island environments is a promising approach for expanding oil storage caverns. However, few researchers have studied the risks of seawater intrusion and the distribution characteristics of intrusion interfaces in large underground water-sealed oil storage caverns in island environments. In this paper, we established a visualized physical simulation platform to investigate the characteristics and control measures of seawater intrusion in single fracture of rock masses within island underground water-sealed oil storage caverns. In addition, the effects of the excavation of caverns, the distance between the cavern and coast, fracture width, seawater level, oil storage stage, water curtain, and water injection pressure were evaluated. The results show that excavation of oil storage caverns carries the risk of seawater intrusion. Specifically, reducing the distance between the oil storage caverns and the coast, increasing the fracture width, and raising the seawater level all contribute to accelerated seawater intrusion into the caverns. However, the vertical water curtain can effectively inhibit seawater intrusion, and increasing the injection pressure of vertical water curtain can avoid the risk of seawater intrusion into the caverns. The research results provide an experimental basis for the study of seawater intrusion in underground oil storage caverns in island environments.
