Case study input data and settings HYDRUS and ORCHESTRA underlying the publication: Coupling ORCHESTRA with HYDRUS to simulate multicomponent reactive transport in variably saturated porous media

Jill A.R. Soedarso, Darrell W.S. Tang, Gabriel Sigmund, Nora B. Sutton et autres

We develop a simple method to couple HYDRUS-OCRHESTRA in one spatial dimension as a proof of concept. This study implements a loose coupling that sequentially simulates HYDRUS then ORCHESTRA. In this dataset you can find a technical explanation of how to couple …

Coupling ORCHESTRA with HYDRUS to simulate multicomponent reactive transport in variably saturated porous media

Jill A.R. Soedarso, Darrell W.S. Tang, Gabriel Sigmund, Nora B. Sutton et autres

We develop and demonstrate the coupling of the variably saturated flow and transport model HYDRUS-1D, with the geochemical reaction model ORCHESTRA, for simulating multicomponent reactive transport in soils and other porous media. We implement a loose coupling of HYDRUS and ORCHESTRA that …

How does cement affect the swelling pressure of bentonite? A modelling approach (CI experiment)

Andreas Jenni, Johannes C. L. Meeussen, Urs Mäder, Lukas Martin

The Mont Terri CI experiment (Cement-Clay Interaction) contains interfaces between concrete and MX-80 bentonite, which were sampled after 5 and 10 years of interaction and characterised. Chemical zonations in the hardened cement matrix indicated mineral reactions found in comparable studies (portlandite, calcium …

Tracer transport in claystones at the core scale: Experiments and modelling

Andreas Jenni, Thomas Gimmi, Johannes C. L. Meeussen, Mirjam Kiczka et autres

Within the Swiss deep drilling campaign 2019–2022, a series of Jurassic (Dogger, Lias) claystone samples were mineralogically and geochemically characterised and used in small-scale transport experiments. The advective-diffusive transport experiments clearly showed a faster breakthrough of anions relative to neutral tracers, which …

Boron Adsorption and Interaction With Phosphate in a Volcanic Soil From the Humid Tropic

Róger Fallas, Juan C. Méndez, Johannes C. L. Meeussen

ABSTRACT Background Boron (B) deficiency is a major constraint for crop production in volcanic soils from humid tropical regions. Its availability can be influenced by adsorption to short‐range order (SRO) minerals and soil organic matter (SOM) and by interactions with other nutrients. …

Geochemistry and machine learning: methods and benchmarking

Nikolaos I. Prasianakis, Eric Laloy, Diederik Jacques, Johannes C. L. Meeussen et autres

Abstract Thanks to the recent progress in numerical methods and computer technology, the application fields of artificial intelligence (AI) and machine learning methods (ML) are growing at a very fast pace. The field of geochemistry for nuclear waste management has recently started …
