Abstract Biological tissues, sediments, or engineered systems are spatially structured media with a tortuous and porous structure that host the flow of fluids. Such complex environments can influence the spatial and temporal colonization patterns of

Most porous systems comprise structures characterized by dead-end and transmitting pores. Here, authors show that macroscopic transport through such porous medium is controlled by structure-induced laminar vortices inside each dead-end pore, and such

Permeable systems can accommodate the flow of fluids through their porous structure that is characterized by solid impermeable grains and empty volumes (the pores). Biofilms are complex and heterogeneous aggregates of communities of microorganisms ad

Disordered microstructures comprising dead-end pores are prevalent in soil, membranes and biological tissues. Predicting transport and dispersal patterns of microorganisms in such media is important for various natural and bio-engineered systems. Her

Sandy streambeds are mobile even at low flow velocities at which sediments can be transported as bedload, more specifically as migrating ripples. Small variations in discharge can result in transitions between sediment transport and no‐transport. D

Predicting dispersal patterns is important to understand microbial life in porous media as soils and sedimentary environments. We studied active and passive dispersal of bacterial cells in porous media characterized by two main pore features: fast ch

Heterogeneity in porous media may occur due to non-uniformity in the sizes or the shapes of grains that comprise the medium. We investigate the transport of colloids in a heterogeneous porous medium engineered in microuidic channels and featuring com
