Abstract
Modeling fluid flow and transport processes in porous media is a relevant topic for a wide range of applications. In water resources problems, this topic presents specific challenges related to the multiphysical processes, large time and space scales, heterogeneity and anisotropy of natural porous media, and complex mathematical models characterized by coupled nonlinear equations. This Special Issue aims at collecting papers presenting new developments in the field of flow and transport in porous media. The 25 published papers deal with different aspects of physical processes and applications such as unsaturated and saturated flow, flow in fractured porous media, landslide, reactive transport, seawater intrusion, and transport within hyporheic zones. Based on their objectives, we classified these papers into four categories: (i) improved numerical methods for flow and mass transport simulation, (ii) looking for reliable models and parameters, (iii) laboratory scale experiments and simulations, and (iv) modeling and simulations for improved process understanding. Current trends on modeling fluid flow and transport processes in porous media are discussed in the conclusion.
Highlights
Transport in Saturated and Modeling flow and transport in porous media (FTPM) has become essential in several scientific fields such as chemistry, biology, agriculture, and mechanics, as well as in several engineering disciplines such as petroleum, civil, thermal, and environmental engineering.In water resources, until early 1950, the studies of FTPM were limited to the upper thin layer of soil and mainly concerned agriculture applications

Summary
Transport in Saturated and Modeling flow and transport in porous media (FTPM) has become essential in several scientific fields such as chemistry, biology, agriculture, and mechanics, as well as in several engineering disciplines such as petroleum, civil, thermal, and environmental engineering. This covers, among others, development of strategies for groundwater resources management and monitoring [1,2], soil and aquifers contamination [3], predictive studies considering climate change and anthropogenic stresses [4,5], groundwater protection [6], seawater intrusion in coastal aquifers [7], thermal storage in aquifers [8,9,10], management of the vadose zone [11,12], geological sequestration of CO2 in aquifers [13,14], environmental management of mines [15], surface–subsurface water exchange [16], waste disposal, and geological repository of nuclear waste [17] In these applications, models of FTPM are mainly used for understanding physical processes and verification of experimental studies. A general conclusion and new trends on modeling FTPM are discussed in the last section of this manuscript
