New academic publications

This year, I co-authored two high-level academic publications. The first one was published with an international selection of hydrological scientists and is published in Water Resources Research:

Fu B, Horsburgh JS, Jakeman AJ, Gualtieri C, Arnold T, Marshall L, Green TR, Quinn NW, Volk M, Hunt RJ, Vezzaro L. Modeling water quality in watersheds: From here to the next generation. Water Resources Research. 2020:e2020WR027721 (online).
 
 
This article lays out systemic difficulties for water quality modelling. My contributions included
  • the initial outlining of the paper in its major sections,
  • a section on soil health and the “soil carbon sponge” that is essential to understand water quantity flows as well as water quality in watersheds, and
  • the model management perspective on orchestrating the multiple knowledge domains and departmental contributions that are required for water quality modelling in watersheds.

 

A second paper was published earlier this year, which summarizes my work around watershed modelling in public-sector agencies. I wrote it with colleagues in Finland and Australia:

Arnold T, Guillaume JH, Lahtinen TJ, Vervoort RW. From ad-hoc modelling to strategic infrastructure: A manifesto for model management. Environmental Modelling & Software. 2020 Jan 1;123:104563.
 
 
I presented it at the Competence Centre on Modelling of the European Commission, who organized the EU Conference on Modelling for Policy support in December 2019. An online recording of this conference is available from their website, my talk starts at 5:05:00 (here).

Model management receives surprisingly little attention, especially if compared with management efforts around data and geospatial data. I believe that reasons are mostly found within the community of modelling experts, who are hesitant to increase transparency around modelling and model-derived products. The paper outlines how modelling processes can be systematized, such that they become manageable for high-level managers and increase the transparency of decision making.
