Special Issue Information

Dear Colleagues,

With continuous population growth and the rapid development of industry and agriculture, the demand for groundwater is increasing day by day. In recent years, studies on simulation of seepage and solute transport have mainly involved hydraulic engineering, petroleum engineering, mining engineering, deep storage of nuclear waste, tunnel engineering, etc. Some environmental problems closely related to human life, such as seawater intrusion, oil pipeline leakage, chemical plant leakage, etc., are strongly tied to groundwater flow and contaminant migration. Therefore, it is very important to study the transportation of groundwater flow and solutes via experimental and numerical simulation. The research results can provide scientific basis for management and decision-making departments.

The objective of this Special Issue is to discuss and analyze the groundwater flow and contaminant transport patterns in porous, fractured and karst media; examine the problems of groundwater leakage, water resource evaluation, foundation pit dewatering, contaminant leakage, and the remediation of groundwater pollution; and to provide new theories, experiments, methods and techniques to solve these problems.

In areas with complex hydrogeological conditions, the tracer test method is often used as an effective means in hydrogeological surveys. According to the results of tracer tests, hydrogeological parameters, including hydraulic gradient and permeability coefficient, fracture network leakage passages and their scale, and groundwater flow rate and direction can be quantitatively determined. This paper takes the upper reservoir of Yongxin Pumped Storage Power Station in Jiangxi Province as the research object, and focuses on the complex hydrogeological conditions of the upper reservoir. Three sets of tracer tests and multiple sets of single-hole flow rate and direction tests were conducted on the left and right banks of the reservoir and near surface gullies. The results showed that ZKS18 received tracers in all three tests, which indicates a close hydraulic connection between ZKS18 and the left bank, right bank, and surface gullies within the reservoir. Based on the single or multiple peak values of the tracer, it was determined that there are 1–6 leakage passages in the fractured rocks, with leakage passage sizes of 0.1–0.4 mm. According to the single-hole flow rate and flow direction tests, a self-developed instrument was used to determine the groundwater flow rate and flow direction at different depths in the test holes, which yielded results that were basically consistent with the results of the three-hole method. These results provide a basis for the use of tracer tests in hydrogeological surveys for water conservancy and hydropower engineering, and anti-seepage design of upper reservoirs. Full article
