The Hydrological Sciences Journal is calling for manuscript submissions to one of several Special Issues.

Karst hydrology: characterization and modelling of flow and transport processes in complex karst systems

Karst hydrology represents a continuously evolving field of research with the scientific community. The unique characteristics of karst systems, in particular the multiple phases involved in flow and transport processes, the various interactions with the land surface, and their heterogeneity at the origin of numerous uncertainties, generate hydrological behaviours that are significantly different from other natural hydrological and hydrogeological systems on earth. Given these peculiarities of karst systems, the community working on karst hydrological phenomena brings together researchers from multiple disciplines, such as hydrologists, hydrogeologists, geologists, mathematicians, physicists and many more. While considerable advances have been made over recent decades to better understand, characterize and forecast the hydrological functioning of karst systems, no attempt has been made to collect these contributions in one journal special issue.

Emerging hydro-climatic dynamics and human–water interactions in a changing world: perspectives from Roorkee Water Conclave 2024

Unravelling spatiotemporal patterns and interactions among climate variables, especially those related to hydroclimate, has always been an important task for geoscientists in general, and for hydro-climatologists in particular, mostly because it contributes significantly to better prediction and forecasting. However, complexities are intrinsic to natural systems, and for this reason the task of identifying patterns and interactions has always been challenging. Coupled with the existing challenges of global warming-induced climate change and human influence, these patterns and interactions become further unusual, unexpected and unpredictable. For instance, the influence of anthropogenic activities on the global water cycle has been significant and has been a major factor in changes in the global water balance. Research findings show that humans are responsible for more than half (57%) of seasonal surface water storage fluctuations. The United States Geological Survey (USGS) recently released a new water cycle diagram, showing humans as part of the hydrological cycle. This Special Issue is expected to advance our understanding of these emerging hydro-climatic patterns, teleconnections, extreme events and human influence in a changing world for more accurate prediction or projection of their changes, especially on different spatial–time scales.

Twenty-first century hydrological challenges and opportunities in Africa.

Africa is endowed with vast surface water and groundwater resources. However, several issues, including climate change, population growth, land use and land cover change, have presented numerous hydrological challenges with consequences for livelihoods, socio-economic development and the environment. There is strong evidence that changes in the hydrological cycle have occurred and will continue to do so in the future. The impacts of these include altered precipitation patterns, rising temperatures and multiplication of extreme weather events, thereby increasing water scarcity, pollution of water resources and uneven distribution of water availability. These changes have profound implications for water supply, agriculture, ecosystems and public health, necessitating a deeper understanding of Africa's hydrological systems. The Twenty-first century hydrological challenges and opportunities in Africa Special Issue offers a platform for experts in hydrology, hydrogeology, climate science, water resources governance and related fields to share their expertise and latest discoveries on the topic across the African continent. This Africa Special Issue is not only an opportunity to highlight pressing challenges but also a platform to showcase innovative solutions and success stories from the African continent. With this Special Issue, we aim to inspire collaborative efforts and promote the exchange of ideas, knowledge and best practice among the African regions and wider global hydrological community.

We are pleased to announce that the Symposium of the International Commission on Continental Erosion (ICCE) will be hosted at the Catholic University of Eichstätt-Ingolstadt, Germany, on July 24th-26th, 2024. The topic is "Sensitivity of erosion and sediment transport to recent climate change". 

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

We invite 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 https://www.ku.de/icce2024, for full information and register for this international yet familiar event! Registration will stay open until March 3rd, but it is advisable to register and book your accommodation as early as possible, because the meeting will take place during the main summer holiday period in Germany.

Early-career colleagues from disadvantaged countries who are eligible are invited to apply for a Sivapalan Young Scientist Award (SYSTA) travel grant for which the deadline is February 16th 2024.

Looking forward to meeting you!

Unveiling the HELPING Emblem of Unity

In an open call that ignited creativity worldwide, we invited the community to craft an emblem that would symbolise our shared commitment to HELPING. A remarkable total of 14 inspiring logos were submitted for consideration. The moment of decision arrived during the IUGG/IAHS General Assembly in Berlin in July 2023 when attendees raised their hands to cast their votes.

The winning design, masterfully created by Judith Boekee from Delft University of Technology, features a globe cradled by hands from across the planet. It's a powerful representation of our global unity and mutual assistance. The red shape within the emblem is a nod to the IAHS logo, reinforcing our connection.

A Journey Documented: HELPING Community Paper

We're excited to announce that a comprehensive community paper documenting the ideas and initialisation of the HELPING decade in progress. This paper will be submitted to the IAHS community journal Hydrological Sciences Journal (HSJ) early next year. Stay tuned for more updates on this significant milestone here.

Nominations are now being accepted for the IAHS Tison and Falkenmark awards, as well as the International Hydrology Prize. Nominations for the awards should be received by the Secretary General, Jean-Marie Kileshye Onema at [email protected], no later than 31 December 2023.

IAHS Tison Award, established in 1982, aims to promote excellence in research by young hydrologists. The Award will be granted for an outstanding paper published by IAHS in a period of two years previous to the deadline for nominations. More information, including the list of previous awards and the nomination process, is available here.

IAHS Falkenmark Award, established in 2022 and is for best PhD thesis recognises outstanding contributions to hydrological understanding of water scarcity and water supply. More information, including the list of previous awards and the nomination process, is available here.

The International Hydrology Prize, awarded annually by IAHS, with UNESCO and WMO, to two people who have made an outstanding contribution to hydrological science. Two medals are awarded under the International Hydrology Prize: the Dooge Medal and the Volker Medal. Both medals are intended to distinguish outstanding achievements by hydrological scientists but with a different focus. The Dooge medal is aimed at fundamental contributions to the science of hydrology, whereas the Volker medal is aimed at outstanding applications of hydrological science for the benefit of society at large. More information, including the list of previous awards and the nomination process, is available here.

It is with great sadness that we have learned of the passing of Professor Malin Falkenmark. She is best known for her long-standing work and expertise on the sustainable use of water resources to meet human and ecosystem needs. Her work is characterized by pioneering integration of both natural- and social-science approaches in global perspectives. She is particularly known for developing the Falkenmark Water Stress Indicator, concepts of Blue and Green water and Comparative hydrology.

She has had a long relationship with IAHS including receiving the IAHS-UNESCO-WMO International Hydrology Prize in 1998 https://iahs.info/About-IAHS/Competition--Events/International-Hydrology-Prize/International-Hydrology-Prize-Winners/MFalkenmark/. In 2022, inspired by her teaching and long contribution to our sector,  IAHS launched a new award in her honour aimed at the best PhD thesis from a financially disadvantaged country https://iahs.info/About-IAHS/Competition--Events/Falkenmark-Award/.

The Stockholm Resilience Centre have written an obituary providing much more information https://www.stockholmresilience.org/news--events/general-news/2023-12-06-malin-falkenmark-water-pioneer-and-academic-mother-of-water-research-has-passed.html.
