ICSH-STAHY Workshop 2024

The fourteenth edition of the STAHY International Workshop, STAHY 2024, will be organized by Pedro Chaffé (Federal University of Santa Catarina) in Florianópolis (Brazil). It will be a combined event together with the 9th International Symposium on Integrated Water Resources Management (IWRM) and the 1st Brazilian Meeting on Statistical Hydrology (EBHE).

The meeting will take place in Florianópolis, Brazil, from 4-7 November 2024.

This joint meeting brings together the experts – academics and practitioners – and young scientists alike for vibrant scientific discussions and debates. We strongly suggest participants to think of how their contributions to the meeting relate to the Themes, Goals and Working Groups of the current IAHS Scientific Decade IAHS initiative for 2023-2032: Science for Solutions: Hydrology Engaging Local People IN one Global world (HELPING). Using the HELPING rationale as the background of our discussions will possibly induce the start and accelerate the development of activities that are already in place in many of the HELPING Working Groups.

We welcome contributions dealing with the following topics (but not limited to):

  • Integrated water resources management,
  • Characterization and prediction of hydrometeorological extremes,
  • Forecast and optimization of water resources systems,
  • Water resources in a connected world.

The conference is eligible for SYSTA travel awards (Sivapalan Young Scientists Travel Award). An abstract must already be submitted to be considered for the award.


Important dates:

31 May – Abstract submission deadline.

31 May – SYSTA Travel Grant Application deadline.

28 June – Notification of abstract acceptance.

15 July – Early bird registration deadline.

15 July – Registration deadline for presenting authors.

28 October – Registration deadline for all participants.

4-7 Nov – Conference dates.

Full information can be found on the conference website.

The eleventh edition of the STAHY International Workshop, STAHY 2021 was organized by by the Research Institute of Water and Environmental Engineering (IIAMA) of the Universtat Politècnica de València (UPV).The event was held entirely on-line due to Covid-19 pandemic condition.

General topics included:
- Extreme hydrological and meteorological analysis under global changes
- Quantifying uncertainty in hydrological predictions
- Hydrological design and risk assessment under changing environment
- Applications of big data, data mining and information theory
- Data assimilation for hydrological forecasts
- New approaches in time series analysis
- Spatio-temporal variability and scaling
- Geostatistics in groundwater and surface hydrology

One day before the Workshop (15 September), the Early Career Course took place, 

Best presentations are invited to a Special Issue in Hydrological Sciences Journal.

It is also noteworthy that during the Workshop Prof. Jose Salas will receive the ICSH Achievement Award for his giant and outstanding contribution to the science of Statistical Hydrology.
