Bed form-induced hyporheic exchange and geochemical hotspots
Faranak Behzadi, Corey D. Wallace, Dylan Ward +1
Small-scale bed form topographies control hyporheic exchange and biogeochemical processes within aquatic sediments, which ultimately affect water quality and nutrient cycling at th…

Convective dissolution of carbon dioxide in deep saline aquifers: Insights from engineering a high-pressure porous Hele-Shaw cell
Saeed Mahmoodpour, Behzad Rostami, Mohamad Reza Soltanian +1
We present the first experiments of dissolution-driven convection of carbon dioxide (CO) in a confined brine-saturated porous medium at high pressures. We designed a novel Hele…

Solutal convection in porous media: Comparison between boundary conditions of constant concentration and constant flux
Mohammad Amin Amooie, Mohamad Reza Soltanian, Joachim Moortgat
We numerically examine solutal convection in porous media, driven by the dissolution of carbon dioxide (CO2) into water---an effective mechanism for CO2 storage in saline aquifers.…
