The International Association of Hydrological Sciences (IAHS) celebrated its centennial in 2022 during the 11th Scientific Assembly held over 29 May–3 June in Montpellier (France); and is celebrating in 2024 a century of publications. This volume materializes the proceedings of the 2022 Assembly and marks the anniversary of the long-term publication dynamics, with articles tackling very actual problems and questions, from across many countries of the World.

The International Association of Hydrological Sciences/Association Internationale des Sciences Hydrologiques (IAHS) was created in 1922 in Rome (Italy) in the form of the International Section of Scientific Hydrology/Section Internationale d'Hydrologie Scientifique of the International Union of Geodesy and Geophysics/Union Internationale de Géodésique et Géophysique (IUGG), itself member of the International Research Council/Conseil International de Recherches both created in 1919 in Brussels (Belgium) (Nature, 1928; Schroeder-Gudehus, 2014, Ismail-Zadeh and Joselyn, 2019) (Names in French language are kept here as it was the language used for the proceedings at the time). The IAHS developed over a century as described by Rosbjerg and Rodda (2019), alongside the parent IUGG (Joselyn and Ismail-Zadeh, 2019; Joselyn et al., 2019) and sister learned societies (including the emergence in 2007 of the International Association of Cryospheric Sciences (IACS); Allison et al., 2019) and with strong partnerships in the United Nations system, in particular with UNESCO IHP and WMO (see e.g. Young et al., 2015a, b; Dixon et al., 2022).

The records of the first plenary meeting of the Section in 1924 shaped the first volume of the Section's bulletin (Section Internationale d'Hydrologie Scientifique, 1924), which then became the Red Book series in 1951 with volume 32 (where the red colour was first used to highlight the cover). This Red Book series developed on an irregular event/opportunity based rationale until volume 368 in 2015, when it was transformed into the Proceedings of IAHS (PIAHS) open access journal (since volume 369 in 2015, with a transitioning integration of volumes 364–368) until this current volume 385​​​​​​​. From this publication dynamic emerged in parallel in 1956 the regular Bulletin d'Information de l'Association d'Hydrologie Scientifique (Tison, 1956), which then became the still very active Hydrological Sciences Journal (HSJ). Ten special volumes (Blue Books) and nine thematic compilations (Benchmark Papers in Hydrology) have also been published since 1989 and 2006, respectively. This century-long series of publications is the oldest and the longest one in international hydrology (https://iahs.info/Publications-News/, last access: 27 October 2024). It has been developed and maintained with intrinsic values which were precursors of the actual Open Science paradigm, articulating science quality with multilingualism, proactive diversity of topics and origins, and processing of both science and operation-oriented knowledge (see e.g. Koutsoyiannis and Kundzewicz, 2007; Cudennec and Hubert, 2008; Koutsoyiannis et al., 2016; Quinn et al., 2018). It has also been relying on peer-editorial volunteership, based on associative in-house publication skills and recent balanced partnerships with publishers (Copernicus for PIAHS and Taylor and Francis for Hydrological Sciences Journal), and minimised or no cost (EUR 30 per published page for PIAHS usually imbedded in a conference budget; free access to HSJ for scientists from low-income countries; long history of pre-digital free dissemination towards key libraries across the World …). The rich records of this publication process are available online thanks to a strong effort of archive rescuing coordinated in the 2000's, and the open access policy of PIAHS and HSJ.

The Montpellier Scientific Assembly was postponed from the initial plan of 2021 because of the COVID pandemic. Despite some residual limitations in travelling from some countries, the Assembly was a successful event organised by a robust and agile local organising committee (grounded in the ICIReWaRD UNESCO Category 2 Center) in partnership with the IAHS governance, which gathered 595 individuals from 57 countries (20 European, 17 African, 10 Asian, 5 South American, 3 North American, 2 Oceanian). Delegates enjoyed the pleasure of meeting again (Fig. 1) to present and discuss science; and to remember the retrospective, benefit from the ongoing, and co-design the future dynamics of IAHS. The latter was facilitated by the momentum and ambiance of the progressing state of the art facilitated by commissions and working groups; of bringing the Panta Rhei decade to a close; of interacting about the Unsolved Problems in Hydrology (UPHs) agenda; of brainstorming about the next decade; and of debating about the paradigm shift of Open Science, the design of the new iahs.info website, the Digital Water Globe, the way to improve the contribution of science to solve the water-related societal challenges, the values and mechanisms of IAHS to facilitate the corporate and inclusive progress (see ISC, 2021; IAHS, 2022). This included debates about hybridisation of onsite and online mechanisms, as experienced for the design of Panta Rhei and of UPHs (Montanari et al., 2013; Blöschl et al., 2019) and knowing the acceleration experienced during the COVID crisis. Cudennec (2024) keeps track of the ten retrospective posters which were curated from the publication and associative records, and displayed during the assembly; and further accompanies with a poetic celebration of the values, history and dynamics of IAHS. Collins et al. (2024), Uysal et al. (2024b) and Volpi et al. (2024) take the opportunity to celebrate the history, legacy and perspectives of respectively the International Commission of Continental Erosion (ICCE), the International Commission on Water Resources Systems (ICWRS), and the International Commission of Statistical Hydrology (ICSH).

Hydrological sciences address multiple compartments, processes, contexts, levels of organisation and scales, which relate to ecological and societal dynamics in terms of environmental determinants, resources, hazards and vectors of compounds. These refer to variability of water quantity and quality; to linkages in particular with human settlements, land use, health, energy, agri-food; and to matters for naturalism, engineering, management, policy, regulation. Ultimately these strongly underlie human rights and dignity, culture, art, socio-economy, development, sustainability, geopolitics, security and foresight. These aspects are at the core of the IAHS history and corporate progress, as shown by the records, with a persistent agenda setting, innovative and synthesis approach in terms of metrology, perception and understanding, conceptualisation and modelling, comparison and standardising. As the World is vast and hydrology materialises heterogeneously, as density and quality of observations and data are critical, as the water dynamics are imbedded in a systemic change, as new societal issues emerge, the science front remains vast. Recently, persistent, revisited and emerging scientific questions have been identified through a community process in the UPH agenda (Blöschl et al., 2019). Prediction in Ungauged Basins has been tackled and corporately advanced during the 2003–2012 decade (Sivapalan et al., 2003; Blöschl et al., 2013; Hrachowitz et al., 2013). Challenges about new observation techniques and emerging citizen sciences have been conceptualised (Tauro et al., 2018; Rangecroft et al., 2021; Nardi et al., 2022; Manfreda et al., 2024). A snapshot of the state of the art about the epistemic, operational and ethical chaining of data-information-knowledge and of data-products-services has been proposed (Cudennec et al., 2020, 2022a), in synchronisation with the shaping of the Open Science paradigm (UNESCO, 2021; Boulton, 2021; Cudennec et al., 2022b; Hall et al., 2022).

The topic of change emerged early in the IAHS debates and achievements, from the assessment methods (e.g. Simojoki, 1960; Maniak, 1968; Blackie, 1970) to the support of management decisions and societal transformations (e.g. Dennisson and Simpson, 1973; Shamir and Loucks, 1989) and to the exploration of plausible futures (e.g. Kundzewicz et al., 1987; Oki et al., 2006). The topic of change has been tackled as a community priority through the Panta Rhei 2013–2022 decade (Montanari et al., 2013; Ceola et al., 2016; McMillan et al., 2016; Di Baldassarre et al., 2019; Tian et al., 2025​​​​​​​; Kreibich et al., 2025), which identified and facilitated a corporate progress on hydrological and socio-hydrological questions in the frame of the Anthropocene, seen as the syndrome of planetary change (Steffen et al., 2011; Bai et al., 2016; Brondizio et al., 2016; Moore et al., 2024) beyond the strict stratigraphic debate (Henderson and Vachula, 2024; Nature, 2024; Richter et al., 2024; Zalasiewicz et al., 2024). The priority on change in the Anthropocene is strong in the UPH Agenda. The new IAHS decade 2023–2032 HELPING, which has just been shaped via a corporate process in a face-to-face/online hybrid mode (Arheimer et al., 2024), prioritises efforts on Science for Solutions in the accelerating developments of the Anthropocene across water-related stakes, levels, scales, contexts and stakeholders.

The scientific programme of the IAHS 2022 Assembly in Montpellier was structured into symposia and workshops proposed and convened by IAHS' commissions, working groups and partners, and was consistent with the above priorities (https://meetingorganizer.copernicus.org/IAHS2022/sessionprogramme, last access: 27 October 2024). All authors who presented in oral or poster form (437 and 148, respectively) at the Assembly were welcome to submit an article for this PIAHS volume. All submissions went through a strict and constructive peer review. The clustering of articles into sections is aligned with the above priorities, as follows: Time variability and change (Asmael et al., 2024; Ben Alaya et al., 2024; Cetina et al., 2024; Follett et al., 2024; Kreis et al., 2024a; Ndiaye et al., 2024; Thakur et al., 2024; Uysal et al., 2024a; Woyessa, 2024); Space variability and scaling (Allam et al., 2024; Kodja et al., 2024; Mokua et al., 2024; Orieschnig and Cavus, 2024); Variability of extremes (Amalaman et al., 2024; Dembélé et al., 2024; Nair et al., 2024; Rosbjerg, 2024b; Senbeta et al., 2024); Interfaces in hydrology (Hadj-Said et al., 2024; Lanini et al., 2024; Lemaire et al., 2024; Mohamed et al., 2024; Ahéhéhinnou Yêdo et al., 2024); Measurements and data (Arnone et al., 2024; Bodian et al., 2024; Estácio et al., 2024; Hanich et al., 2024; Kreis et al., 2024b; Mazzoglio et al., 2024; Navas et al., 2024; Omar et al., 2024; Ouachani et al., 2024; Yao et al., 2024); Modelling methods (Ajjur and Al-Ghamdi, 2024; Amoussou et al., 2024; Beven et al., 2024; Gbohoui et al., 2024; Jay-Allemand et al., 2024; Kouadio et al., 2024; Onyutha, 2024; Pesce et al., 2024; Savenije, 2024; Tanguy et al., 2024); Interfaces with society (Andreu et al., 2024; da S. Alves et al., 2024; Diémé et al., 2024; Garin et al., 2024; Gesualdo et al., 2024; Hzami et al., 2024; Nortes Martinez et al., 2024; Petruccelli et al., 2024; Ogbu et al., 2024; Pacheco and Alves, 2024; Rosbjerg, 2024a); A focus on water and agriculture (Abid et al., 2024; Chakhar et al., 2024; Contreras et al., 2024; Ferchichi et al., 2024; Khardi et al., 2024; Mekki et al., 2024; Merheb et al., 2024; Romashchenko et al., 2024; Saracho et al., 2024; Sousa et al., 2024; Vandôme et al., 2024); and a Focus on Open Science (Benveniste et al., 2024; Legay et al., 2024; Loree et al., 2024; Nonki et al., 2024; Paturel et al., 2024; Yépez et al., 2024). First 7 are clusters of UPH as identified by Blöschl et al. (2019). Last two are foci which have been much represented and discussed in IAHS2022.

As in any edited volume, such a chaptering offers an intra-volume consistency and curation for a reader who considers the volume as such. Yet, for a literature reviewer in the actual busy landscape of scientific publication and communication, or a text miner, finding and assimilating all articles and results which contribute to a scientific question is a digital, cognitive and epistemic challenge. For that reason, using standard keywords in order to label articles against ad hoc initiatives, questions, agenda items can be helpful (Stein et al., 2022). This was identified within IAHS some years ago (and catched by Quinn et al., 2018) and is actively proposed by HSJ and by the Water Digital Globe (https://iahs.info/Initiatives/digital-water-globe/, last access: 27 October 2024) with UPHs, SDGs and their targets. It has also been proposed to authors publishing in this PIAHS volume as a bulk experiment with the following rationale for listing labelling and free keywords:

  • If relevant: “UPH” or “UPH xx”, where xx is the number between 1 and 23 as in Blöschl et al. (2019)

  • If relevant: “SDG”, “SDG xx”, “SDG xx.yy”, where xx is the number of the SDG between 1 and 17 or xx.yy the number of the specific target, as per the Agenda 2030 mechanism.

  • Other possible keywords related to an Agenda setting initiative, whenever relevant, or main approach: “Open science”, “PUB”, “Panta Rhei”, “Citizen science”, “New monitoring”, “Field observation”, “Conceptualisation”, “Modelling”, “Indicator”, “Visualisation”

  • 1–2 free geographic/hydrographic keywords

  • 1–2 free thematic/process/methodological keywords

Table 1 shows how this proposition of labelling keywords has been used across the articles of this volume (completed by free keywords). One can see that PUB is still referred to even if the decade was closed in 2012, confirming that the wavelength of such an agenda is much longer that the decadal time window. References to Panta Rhei are not many, but can be detected through the use of several of the UPHs which extend Panta Rhei questions. No reference to the new HELPING decade is explicit as it was formulated after, but the ambition of having a science-for-solution approach was in the air in IAHS2022 and can definitely be identified across this volume, with references to SDGs and their targets, and beyond. The experiment of encouraging authors to curate their article with proposed labelling keywords proves to be useful; yet incomplete as it appears that some articles could have been explicitly labelled more completely and/or precisely. This confirms that scientific review and synthesis still require a blend of knowledge management procedures and of expert intelligence. This further confirms – we believe – the relevance of a 100 years-old learned society like IAHS in an epoch where hydrology is critical to understand and mitigate the Anthropocene syndrome, where science is at stake in the (dis)information society, and where “Artificial Intelligence” has to be developed without biases and kept smart.
