High Performance computing for quantifying climate change impacts on Boreal Areas

HiPerBorea is a research project coordinated by the Geosciences Environment Toulouse (GET) laboratory and funded by the french National Research Agency (ANR) for the period 2020-2023. The objective of this project is to enable quantitative and predictive modeling of cold regions hydrosystems evolution under climate change. Arctic and sub-arctic areas, which are highly vulnerable to global warming, are largely covered by permafrost – soil that is year-round frozen at depth. Permafrost-affected areas, which represent 25% of emerged lands of the northern hemisphere, are prone to major biogeochemical and ecological transformations due to permafrost thaw, with strong associated feed-backs on greenhouse gas cycling (degradation of previously permanently frozen organic carbon pools). We will use advanced numerical modelling build on the permaFoam solver (the OpenFOAM® solver for permafrost modelling, see Orgogozo et al., 2019) to help predict the impact of permafrost thaw on arctic thermo-hydrologic functioning. By doing so, we will provide mechanistic understanding of Arctic change, that is necessary to further understand carbon cycling and contaminant/nutrient transport, and to further assess risk and opportunity for sustainable urbanization, agriculture and general sustainable development of the (sub-)Arctic.

Presentation of HiPerBorea at the 13th Asian Computational Fluid Dynamics conference

HiPerBorea participated to the 13th Asian Computational Fluid Dynamics conference, held in Jeju on the 17th, 18th and 19th of October 2022. Presenting the project to the asian CFD community was the occasion of many interesting and fruitful discussions. The presentation given at this conference may be found here.

Permafrost modelling with OpenFOAM ® : New advancements of the
permaFoam solver

In September 2022 a new version of permaFoam, the OpenFOAM solver for permafrost modelling, has been published in Computer Physics Communications as a Computer Programs in Physics contribution by Orgogozo, Xavier, Oulbani and Grenier. In this work, the massivelly parallel computing capabilities are studied on supercomputers of CALMIP and of the TGCC, and example of […]

Field mission in Abisko – July 2022

On July 2022 a field mission to Abisko Research Station in Northern Sweden has been done. The goals were to produce a new vegetation map for Stordalen and Mielajokka catchments (see the previous HiPerBorea field mission in Abisko) based on satelite data (Auda et al., in prep) and to sample sphagnum mosses from the peatlands […]

Participation to the 5th French/Belgian OpenFOAM® users conference

At this workshop of the FOAM-U association held at the IFPEN nearby Lyon on 17th-18th May 2022, the french/ Belgian community of OpenFOAM users get anew the chance to exchange and discuss in a numerical and friendly atmosphere – a relief after these long lasting covid-19 times ! Here is the presentation given at this […]

Presentation to the french committee of arctic and antarctic researches (CNFRAA)

The participation to the 18th scientific days of the CNFRAA (Comité National Français pour les Recherches Arctiques et Antarctiques – national french committee for the arctic and antarctic researches) held in Toulouse on 10th-11th of May 2022 has been the opportunity to present HiPerBorea to the french polar community. Interesting and exciting days ! Here […]

Release of RichardsFoam3

RichardsFoam3 is an updated version of the OpenFOAM solver RichardsFoam, previously presented in ”An open source massively parallel solver for Richards equation: Mechanistic modelling of water fluxes at the watershed scale” by Orgogozo et al. (2014), and in the new version announcement ”RichardsFOAM2: a new version of RichardsFOAM devoted to the modelling of the vadose […]

HiPerBorea presentations at the 6th International Field Symposium: West Siberian Peatlands and Carbon Cycle: Past and Present – WSPCC 2021

The WSPCC 2021 held in Khanty-Mansiysk in early July as been the occasion to put forward the actions of HiPerBorea for permafrost modeling in the northern peatlands, and especially in the Western Siberian Lowlands. Since the Khanymey INTERACT scientific station is one of the four key sites considered in the project, it is indeed an […]

Field mission in Abisko, Northern Sweden

The two considered catchments are contiguous, lying in a sub-arctic climate, discontinuous permafrost region. Miellajokka catchment is a more montainous catchment, while Stordalen encompasses a large lowland area with peatland and lakes in its northern parts. Please find below the locations and some photographies of these two watersheds.
