5th Space for Hydrology Workshop

Hydrospace 2023 ; 27 November - 1 December 2023 ; FIL Lisbon, Portugal
27 Nov - 01 Dec 2023
Lisbon, Portugal

The European Space Agency, in the context of the "Earth Observations Science for Society" Programme, the Global Energy and Water EXchanges project (GEWEX) of the World Climate Research Programme and Centre National d'Études Spatiales (CNES) are organising a sequel joint event to Hydrospace2021 and EO4Water2020, called 5th Space for Water Cycle and Hydrology Workshop, HYDROSPACE 2023. 

HYDROSPACE 2023 aims at reviewing the latest advances in the use of Earth Observation (EO) technology for water cycle science, hydrology and its applications, exploring the potential offered by the existing and coming EO satellites together with advanced modelling and novel technologies as well as the main challenges and opportunities to enhance our current capacity to observe, understand and predict the water cycle, and its impacts and feedbacks with human activities and ecosystems.

The ultimate target of the event is to review the state of the art and latest developments in EO for water research and hydrology and contribute to define a community scientific agenda that may drive future scientific activities of ESA and other space agencies and partners to face one of the main societal challenges of our days. 

The HYDROSPACE 2023 Workshop is open to EO scientists, water researchers and students, modellers, Earth system and climate scientists, industry, operational agencies, policy makers, representatives of local communities and other stakeholders interested in sharing their knowledge and experience and in contributing to drive the scientific agenda for advancing EO water research and future applications.

  • Reviewing the latest advances and results in the use of EO technology to monitor and characterise the different components of the water cycle (terrestrial hydrology, ground water, atmosphere, oceans, mountain ranges and glaciers), hydrological processes and its interactions with human activities and ecosystems.
  • Reviewing the progress in understanding the water cycle cycle as well as its variability and sensitivity to climate change including hydro-climatic extremes with related compound and cascade events.
  • Reviewing the progress of novel EO-based high-resolution data, methods, and approaches for modeling the water cycle at basin scales targeting spatial and temporal scales compatible with decision making. 
  • Exploring the status of future EO missions under preparation by space agencies and industry and latest advances in novel EO technologies, future mission concepts and new mission ideas for water cycle research and hydrology.
  • Exploring opportunities offered by the effective integration of latest EO data, AI, advanced models, information technology and communication, cloud computing and high-performance computing capabilities for developing Digital Twins, fostering open science and developing novel applications serving policies and society.  
  • Fostering networking and collaborative research in water sciences, bringing together different expertise, data and resources in a synergistic manner ensuring that the final result may be bigger than the sum of the parts.
  • Identifying the major scientific challenges, observation gaps and research needs for the coming years and advancing towards the definition of major scientific priorities in water cycle research that may drive scientific activities of ESA and other partners in the coming years.
