Join Us for the HEPEX 2025 Workshop – Celebrating 20 Years of Advancing Hydrological Forecasting
Shaping the Future of Hydrological Forecasting:
HEPEX 2025 Workshop and Anniversary!
25-27th March 2025, Tuscaloosa, United States
The final Agenda is now ready!
We are thrilled to see the enthusiasm and high interest in our upcoming workshop!
Keynote talks
Title: HEPEX: Meeting the promise and challenges of probabilistic streamflow forecasting
Prof. Stefan Uhlenbrook’ s main expertise includes water management in a changing climate, hydrological processes and modelling across scales (i.e., floods and droughts), and the water-energy-food-ecosystems nexus. Stefan leads the Hydrology, Water and Cryosphere branch of WMO, the UN Specialized Agency for Weather, Climate and Water. He is excited to contribute to the Organisation’s program and, among other things, strengthen the early warning systems for floods and droughts as well as water resources assessment and management worldwide. Title: Global efforts to enhance hydrological forecasting In response, WMO has intensified its support to countries, aiming to minimize these impacts through the development technical guidelines, manuals and implementation of hydrological forecasting systems (usually through extra-budgetary projects). Capacity building and enhanced cooperation among global, regional, transboundary and national stakeholders remain central to these efforts. The Assessment Guidelines for End-to-End (E2E) Flood Forecasting and Early Warning Systems (FF&EWS) provide National Hydrological Services (NHSs) worldwide with a structured framework to evaluate their capabilities and enhance their ability to deliver accurate, timely, and actionable flood forecasts. Additionally, the Inventory of Interoperable Models and Platforms for FF & EWS offers valuable guidance for scientists and engineers in NHSs selecting suitable models and platforms, supported by screening criteria to ensure success. A Community of Practice are for E2E FF&EWS is under development to facilitate the exchange of knowledge and experiences. Multiple hydrological models, platforms and systems have been successfully implemented by the WMO Members, particularly Least Developed Countries, supported by external financial and technical assistance. Emerging technologies, including artificial intelligence (AI), the metaverse, and digital twins, are being actively explored to advance hydrological forecasting capabilities. An ongoing AI pilot study in four volunteer countries is generating valuable insights, while case studies on these innovative technologies have been collected to evaluate their potential for operational implementation. To ensure sustainability, the Research-to-Operation (R2O) plan has been initiated, promoting the seamless integration of research advancements into operational systems. The plan fosters a collaborative development culture, ensuring broader and more inclusive participation form the global hydrological community. This approach underscores WMO’s commitment to strengthening hydrological forecasting systems, building resilience to extreme weather impacts, and supporting informed decision-making at all levels. Combined with the experiences and successes of HEPEX during the last 20+ years, this provides a unique opportunity for tangible impact in the developing world in the future.
Title: Machine learning advances, from theory to applications to operations, improved predictions and understanding our physical world |
Hydrological forecasting is vital for managing water resources and mitigating risks from floods and droughts. Over the past 20 years (2004-2024), HEPEX has played a key role in advancing this field by uniting researchers, practitioners, and stakeholders to enhance ensemble prediction systems and improve water management decisions. By bridging the gap between research and operations and fostering collaboration across various sectors, HEPEX has promoted the development of forecasting systems that address end-user needs and emphasize uncertainty quantification.
In 2025, we celebrate the 20th anniversary of the HEPEX initiative with a landmark workshop that brings together researchers, operational forecasters, practitioners, and users from around the globe. This event will focus on the latest developments in hydrological forecasting and its applications across water-dependent sectors. Our sessions will explore the future research agenda for the next decade, with a strong emphasis on sectoral needs and scientific opportunities. We are especially eager to involve Early Career (EC) scientists from our EC-HEPEX group, who will contribute fresh perspectives and innovative ideas.
Participation in the workshop is open, although in-person attendance is limited by venue capacity, and registration is required for all participants. For information on accommodation and travel, please see below.
