Special Issue Information

Dear Colleagues,

Fluid flow through porous materials is a complex phenomenon which generally covers a wide variety of engineering disciplines concerning theoretical research, fundamental studies, mathematical modeling, numerical simulations, and experimental investigations relating to any kind of current and emerging topics of groundwater flow.

In this Special Issue, we encourage submissions focusing on numerical methods, including meshless methods, conventional finite difference/element methods, and the radial basis function method for solving problems of groundwater flow.

We particularly welcome contributions that aim to seek to advance meshless methods for modeling groundwater flow. This Special Issue welcomes high-quality submissions of theory and/or simulation works which focus on both analytical and computational research, with an emphasis on contributions which increase the basic understanding of groundwater flow in porous materials and their application to engineering problems. This Special Issue is also open to review articles which describe the current state-of-the-art.

Potential topics include but are not limited to the following:

  1. Meshless methods (including boundary element methods, method of fundamental solutions, Trefftz method, general finite difference method, and radial basis function method) for modeling the behavior of groundwater flow;
  2. Offshore geophysical groundwater investigation or modeling;
  3. Coastal groundwater investigation or modeling;
  4. Inverse problems in groundwater flow;
  5. Parameter identification in groundwater flow;
  6. Analytical methods for solving problems of groundwater flow;
  7. Fluid flow and transfer in porous media;
  8. Applications of groundwater flow in engineering;
  9. Other topics on transport phenomena or heat and mass transfer in porous media.

Predicting the effects of changes in dissolved input concentration on the variability of discharge concentration at the outlet of the catchment is essential to improve our ability to address the problem of surface water quality. The goal of this study is therefore dedicated to the stochastic quantification of temporal variability of concentration fields in outflow from a catchment system that exhibits linearity and time invariance. A convolution integral is used to determine the output of a linear time-invariant system from knowledge of the input and the transfer function. This work considers that the nonstationary input concentration time series of an inert solute to the catchment system can be characterized completely by the Langevin equation. The closed-form expressions for the variances of inflow and outflow concentrations at the catchment scale are derived using the Fourier–Stieltjes representation approach. The variance is viewed as an index of temporal variability. The closed-form expressions therefore allow to evaluate the impacts of the controlling parameters on the temporal variability of outflow concentration. Full article
