We are pleased to announce the inaugural Editor-in-chief for the Digital Water Globe (DWG): Prof. Eduardo Mario Mendiondo of the University of São Paulo - São Carlos School of Engineering. The DWG is a web-based software platform where IAHS members share Case studies, Personal profiles, IAHS references and links to data repositories. The different items are linked to a geographical position on a global map as well as keywords for quick search using filter functions. The DWG offers co-creation and re-examines the role of scientific outreach by exploring novel digital ways to interact between scientists and society for mutual understanding and co-evolution. Most of all, the DWG will exploit the potential of an innovative digital arena for IAHS-community building, data/knowledge exchange and science communication in action. We invite you to view and contribute to the DWG!

The International Association of Hydrological Sciences (IAHS) is proud to announce dates and venue of the first edition of the IAHS Academy, the newly established advanced training and educational programs to advance and promote hydrological sciences globally. The IAHS Academy 2024. The date of the first edition of the IAHS Academy is set for 20-27 July 2024 and will be hosted in Cairo, Egypt.

Dear colleagues,

This is a final reminder regarding the Symposium of the International Commission on Continental Erosion (ICCE) of the IAHS that we’re proud to host at the Catholic University of Eichstätt-Ingolstadt, Germany, 24-26 July 2024. The registration deadline is 3 April 2024.

As the anthropogenic alteration of global climate and its specific regional features become more and more evident, the symposium aims to shed light on recent progress and research avenues regarding the sensitivity of erosion and sediment transport to recent climatic and environmental changes. This topic spans multiple compartments of geosystems such as:

• processes on hillslopes and slope stability
• fluvial processes, river planform changes and sediment budgets
• aeolian sediment dynamics.

Consequently, we’re open for contributions related to different environments of the Earth and hope to stimulate discussion and collaboration. As many of the aforementioned processes affect human life, societies and economy, we are interested in both basic and applied research. Your presentation might also show methodological innovations leading to better measurements and understanding of erosion and sediment transport in the past, present and future.

The venue is located in central Bavaria, between Munich and Nuremberg (airports) and can be reached by national and international train connections. Please visit our conference website and consider registering for this international yet familiar event!

We are looking forward to meeting you.

With apologies for cross-posting, we are sending out the 3rd call for papers for the symposium of the International Commission on Continental Erosion (ICCE) of the IAHS that we’re proud to host at the Catholic University of Eichstätt-Ingolstadt, Germany, on 24-26 July 2024. As more colleagues have started registering in the last few days, we decided to extend the initial registration deadline to 3 April 2024. Please bear in mind, however, that the deadline for the hotel rooms we have pre-reserved for conference participants (see conference website) cannot be postponed as the meeting will take place during the main summer holiday period in Germany. It is therefore recommended to register and book your stay as soon as possible.

"Post-fire hydrologic analysis: A tale of two severities" suggests that a “tactical pause” is required to re-evaluate the concepts of fire/burn severity, with important implications for fire management and post-fire hydrological modelling. The paper highlights the importance of distinguishing between vegetation burn severity and soil burn severity when assessing post-fire hydrologic impacts, highlighting the need for a more nuanced approach. It also discusses the potential synergistic future of remote sensing with in-situ severity metrics, suggesting that combining these data sources could lead to more accurate and reliable predictions. We look forward to initiating a broader discussion on post-fire hydrologic analysis. Your discussion and research papers are welcome! The paper is free to view for six months.

Issue 2 Featured article - imminently free to view for six months

A key new HSJ review paper.
We are delighted to feature the publication of a particularly innovative and somewhat controversial HSJ paper by former Editor-in-Chief Demetris Koutsoyiannis and Christos Vournas. The article, titled “Revisiting the greenhouse effect—a hydrological perspective”, is written in Demetris Koutsoyiannis's signature style, combining humour with a hydrological perspective on a topical issue. The study challenges conventional thinking on the greenhouse effect and offers a new perspective that is sure to stimulate scientific discussion: old formulae for calculating the greenhouse effect are still accurate, the authors claim, even with more carbon dioxide in the atmosphere.

The target audience would include students, researchers, NGOs, scientists, academicians, policy makers, and working professionals. More information regarding the Roorkee Water Conclave 2024 is available here.

Session Scope

We welcome presentations describing contemporary hydrological research efforts, which aim to solve fundamental water-related environmental and societal problems by engaging with other disciplines and local stakeholders.

The increasing demand for water due to population growth and globalization, coupled with the impact of climate change, has made water security a global issue that affects the economic, social, and environmental sustainability of many regions and communities. In order to ensure safe water supply for human and environment, and protecting them from water hazards in the present circumstances, hydrological knowledge is needed more than ever. However, scientific knowledge on resilience and water security is fragmented in discipline, people, and place. There is a substantial lack of synthesis and easily digestible scientific messages among hydrologists, across disciplines and from scientists to practitioners, decision-makers and the general public. Hence, there is a need for the hydrological research community to take the lead and better link local hydrological research with global patterns of the water cycle, and further, to provide science-based water-centric decision support for local sustainable water management.

Therefore, the IAHS is dedicating the next scientific decade to science for solutions. The name HELPING, stands for Hydrology Engaging Local People IN one Global world and aims to identify local water problems in holistic/system analyses, search for solutions, be bold and push boundaries to make an impact. The vision is to solve fundamental water-related environmental and societal problems by engaging with other disciplines and local stakeholders. This special session will focus on the 3 Themes of HELPING, which all aim to understand hydrological diversity and integrate knowledge across scales and regions to achieve sustainable water management in coherence with the local context;

Theme 1: HELPING with global and local interactions using systems analysis, to develop enhanced understanding of the global water crisis but from a local lens.
Theme 2: HELPING with holistic solutions to the water crisis, embracing nature-based measures, participatory management and nexus analysis including other disciplines and multiple stakeholders.
Theme 3: HELPING with cross-cutting approaches to facilitate the above goals, including science communication, integrating new technologies, and fostering local co-creation processes.

The New Science For Solutions Decade HELPING

IAHS has proudly and successfully coordinated two Scientific Decades, which, amongst other things, set the research agenda worldwide through collaborative forces. The overall aim with a scientific decade is to accumulate knowledge and streamline the efforts so that coherent engagement, sharing and focus accelerate scientific knowledge and understanding of a specific hydrological problem or phenomena. It stimulates vivid discussions between young and senior scientists globally. The third Scientific Decade 2023–2032 of IAHS launches a topic for collaborative efforts in hydrological sciences: HELPING, created through a participatory community process and by applying strategic planning. The this Scientific Decade is dedicated to local solutions under the global water crisis. The name HELPING, stands for Hydrology Engaging Local People IN one Global world. This decade is a bottom-up process empowered by local hydrologists and scientists using open science and local data/methods when solving local water problems. We envisage that the building of local knowledge and cooperation will inform scientists working under similar situations or facing unexpected events worldwide.

The spirit of HELPING collaboration and innovation is in full swing and we are excited to share that our global community is coming together to make a meaningful impact to understand and handle the water crisis of the Anthropocene. The journey ahead for the HELPING Working Groups promises excitement, growth, and an opportunity to make a meaningful impact. Currently there are 26 Working Groups attracting from 8 up to 136 people in each (median value is 56 participants). We invite all of you to be part of this incredible adventure. You can join an existing Working Group and contribute to the collective efforts. Together, we will redefine what's achievable and set new standards for success. With joint efforts we can make a difference as a community, and we're excited to have you on board.
