Rate equations, spatial moments, and concentration profiles for mobile-immobile models with power-law and mixed waiting time distributions

TJ Doerries, AV Chechkin, R Schumer, R Metzler - Physical Review E, 2022 - APS
We present a framework for systems in which diffusion-advection transport of a tracer
substance in a mobile zone is interrupted by trapping in an immobile zone. Our model …

Tide-induced infiltration and resuspension of microplastics in shorelines: Insights from tidal tank experiments

Q Feng, Z Chen, C An, X Yang, Z Wang - Water Research, 2023 - Elsevier
In the present study, the infiltration and resuspension of microplastics (MPs) in a slope
substrate under the influence of repeated tidal forces were investigated using a tidal tank. In …

Persistence of antibiotic resistance genes varies with particle size and substrate conditions in recirculating streams

O Ginn, JL Tank, A Badilla-Aguilar… - Environmental …, 2023 - ACS Publications
Antibiotic resistance (AR) determinants are enriched in animal manures, a significant portion
of which is land-applied as a soil amendment or as fertilizer, leading to potential AR runoff …

Streambed immobilization controls the transport of antibiotic resistance genes in flowing water

A Badilla-Aguilar, DMC Hallack, O Ginn, E Snyder… - Water Research, 2024 - Elsevier
Antibiotic resistance is a serious global health issue, resulting in at least 1.2 million deaths in
2019. The environment is a potentially important reservoir of antibiotic resistance; however …

Numerical evaluation of photosensitive tracers as a strategy for separating surface and subsurface transient storage in streams

SS Rathore, AS Ward, SL Painter - Journal of Hydrology, 2023 - Elsevier
We numerically evaluated photosensitive tracers as a potential strategy for separating the
effects of surface and hyporheic storage zones (SSZs and HSZs, respectively) on stream …

Coupled biological and hydrological processes shape spatial food-web structures in riverine metacommunities

HC Ho, F Altermatt, L Carraro - Frontiers in Ecology and Evolution, 2023 - frontiersin.org
