I was invited to explain the idea of Digital Twins of the Earth System at the IAEG Summer School in Aosta. This time it was in person — a welcome change from the Chandigarh and Bern talks, which were both online — and the occasion was a good reason to rework and rearrange material I had used before.
The talk followed this outline:
- Earth Digital Twins — the general idea
- Models
- New ways to do software
- Steps towards DARThs
- Working for Science
- Enabling Technologies
- Open Science and participation
(For anyone who wants the definition itself — what a DARTh actually is — I set it out separately, as thirteen tenets, in an earlier post, after my talk)
From my by-now rather large collection I had also prepared a few further sets of slides covering the processes of interest (the flesh to add to the bone). I did not manage to show them, for lack of time, but they follow the same thread, and I am leaving them here for anyone of IAEGists curious to see where we think this is heading:
- GEOtop EO — an older presentation on using GEOtop to anticipate the location and timing of shallow landslides: an example of a piece of existing software that could grow into a DARTh.
- Some results from the Morfeo Project (2008), along the same line.
- DARThs 2027 — where we stand today, and the perspective under which we are working.
- A message to the young — a few words for early-career researchers.
- Catchment processes (or the processes we need to implement)
I should be honest about that last group. The closing part of the DARThs 2027 presentation is still under construction: it needs more thinking, and a deeper reading of several resources I cite but with which I have no direct experience yet. It is, frankly, a work in progress — and I would rather say so than pretend otherwise. If any of it is useful to you, or if you see where it should go next, I would be glad to hear from you.
Because you are probably interested in landslides and, consequently on Richards equations, and its generalizations, you can find material here:
- The various post I did in the last fifteen years
- The WHETGEO model integrating Richards
- An incoming new theory for the movement of water in the vadose zone under disequilibrium
- My Massive Open Online Course on water in soil (incoming, July 10)
Slides: the presentation (and the additional sets mentioned above).
Video: the recording of the talk will be added here once it is available — [to come].
