Special Issue Information

Dear Colleagues,

The Special Issue on “Flow and Transport Processes in Groundwater Systems” focuses on recent advances and prospects of groundwater studies including, but not limited to:

  • Fundamental investigations addressing various experimental techniques, mathematical and numerical modeling of physical mechanisms for fluid momentum, and energy ranging from inertia to drag dominant balances, stochastic and deterministic methods, big data decision support, management strategies, and experience learned from case studies;
  • Monitoring and prediction of groundwater flow and solute migration at different spatial and temporal scales, hydrogeochemistry, karst, freshwater–saltwater interactions, groundwater contamination, remediation, risk analysis, and protection;
  • Effect of heterogeneity on dynamic and distribution of contaminants, calibrating flow and transport models, and uncertainty associated with predictions and observations.

We invite contributions from researchers involved with experimental and theoretical aspects linked to water flow and solute migration, with application to water resources, groundwater contamination and remediation, mining and hydrocarbon geology, geothermal resources, and related areas. 

By presenting this integrative and multidisciplinary volume, we aim to transfer new knowledge to hydrologists, water resources planners, and policymakers engaged in the sustainable development of groundwater resources.

A fully penetrating cut-off wall is a vertical seepage barrier that fully penetrates an aquifer and is embedded in an underlying aquitard to a certain depth. Groundwater seepage with this type of wall occurs through three paths: leakage through the body of the wall in the aquifer, leakage through the body of the wall embedded in the aquitard, and seepage under the wall. Seepage through the first path can be simply treated as one-dimensional flow. However, due to the mutual influence of seepage through the latter two paths, the seepage problem is complicated and still needs to be studied. An analytical method is proposed to solve this problem in this study. Mathematic expressions for flow rate and head value are obtained by superposition of drawdowns of two exact models, namely, the model with only leakage through the wall body and the model with only seepage under the wall, respectively. Exact solutions are quoted or derived for the exact models, but they involve Legendre’s elliptic integrals of the first and third kinds. To facilitate an engineering application, approximate models of the exact models are introduced and their solutions are applied to the analytical formulas. The accuracy and applicability of the proposed method are verified compared with the numerical method. The proposed method provides a simple but effective method for quickly estimating the quantity of seepage in the aquitard (including leakage through the wall body and seepage under the wall) when simultaneously considering the effects of wall permeability and thickness.

In order to evaluate the impact of groundwater drainage on groundwater flow, the Hetaoyu coal field was taken as a case study in the Longdong area, China, where the coal seam was covered with multilayer aquifers. A three-dimensional unsteady groundwater flow model and a one-dimensional fracture water flow model were calculated by joint equations for changing hydrogeological structures under coal mining. According to the results, mine construction had greatly affected groundwater reserves in the Quaternary phreatic aquifer, Cretaceous Huanhe confined aquifer, and Luohe confined aquifer. The groundwater drainage was mainly from the Cretaceous aquifer, in which the aquifer reserves of the Luohe Formation decreased by 30,861.8 m3/m, accounting for about 92% of the total changes in local groundwater reserves. A drop funnel with an area of about 2.3 km2 would be formed under the groundwater discharge of 187.6 m3/h for the main inclined shaft excavation of the Hetaoyu coal mine. With the continuation of mining activities, the mine water flow will reach 806.83 m3/h and would result in descending funnel area of about 4.5 km2, the groundwater level drawdown at least 16 m, which would exceed the limited value regulated by the government. Therefore, in order to ensure the safety of coal mining and protect groundwater resources, the Hetaoyu Coal Mine departments should take some water loss prevention and control projects to reduce the drawdown of groundwater.
