Learning Constitutive Relations From Soil Moisture Data via Physically Constrained Neural Networks
WATER RESOURCES RESEARCH
03 july 2024
Toshiyuki Bandai, Xingyuan Chen, Teamrat A. Ghezze...
The constitutive relations of the Richardson‐Richards equation encode the macroscopic properties of soil water retention and conductivity. Th...
Pore‐Scale Modeling of Reactive Transport with Coupled Mineral Dissolution and Precipitation
WATER RESOURCES RESEARCH
21 june 2024
Ziyan Wang, Mengsu Hu, Carl I. Steefel
We present a new pore‐scale model for multicomponent advective‐diffusive transport with coupled mineral dissolution and precipitation. ...

Modeling Reactive Transport and Chemo-Mechanical Processes in Rough Fractures
REACTIVE TRANSPORT AND CHEMOMECHANICAL PROCESSES IN POROUS MEDIA I ORAL
hydrology | 15 december 2023
Carl I. Steefel, Mengsu Hu
Rough natural fractures typically show asperities at the scales of 10-100 microns that may keep the fracture open and transmissive. In the case of car...

Pore-Scale Modeling of Simultaneous Mineral Dissolution-Precipitation Coupled with Flow and Reactive Transport
REACTIVE TRANSPORT AND CHEMOMECHANICAL PROCESSES IN POROUS MEDIA II POSTER
hydrology | 15 december 2023
Ziyan Wang, Mengsu Hu, Carl I. Steefel
It is very challenging to address rigorously the processes of flow, advection, diffusion, and reaction at the pore-scale because these are typically s...
