Understanding mechanistic causes of non‐Fickian transport in fractured media is important
for many hydrogeologic processes and subsurface applications. This study elucidates the …

Bacterial biofilms can form in porous media that are of interest in industrial applications
ranging from medical implants to biofilters as well as in environmental applications such as …

Pore-scale velocity and turbulence structures near streambeds may control solute transport
and dispersion in streams. In this study, pore-scale flow and transport simulations are …

Improved understanding of stream solute transport requires meaningful comparison of
processes across a wide range of discharge conditions and spatial scales. At reach scales …

Rivers transport contaminant microorganisms (including fecal indicator bacteria and human
pathogens) long distances downstream of diffuse and point sources, posing a human health …

An analytical expression is presented for the shear dispersion during solute transport in a
coupled system comprised of a capillary tube and a porous medium. The dispersion …

Turbulence causes rapid mixing of solutes and fine particles between open channel flow
and coarse‐grained streambeds. Turbulent mixing is known to control hyporheic exchange …

Microbial biofilms are ubiquitous within porous media and the dynamics of their growth
influence surface and subsurface flow patterns which impacts the physical properties of …

Coinjections of conservative tracers and nutrients are commonly used to assess travel time
distributions and nutrient removal in streams. However, in‐stream tracer data often lack …

Several earlier studies reported that microplastics (MP) accumulated on soil surfaces could
be transported into the subsoil and ingested by soil biota, such as earthworms. The present …
