Reliable seasonal streamflow forecasts could be a valuable tool for the medium-term to long-term planning of many users of the water sector.

This holds for the optimization of hydropower generation, water-related logistics as well as for irrigation management and others.

The knowledge about the possible future evolution of streamflow within the next months would be important additional information in related decision processes. Although there is a strong need for seasonal forecast products, there are only a few seasonal hydrological forecasting systems operational yet. One of the main reasons is that the long-term meteorological predictability, especially for precipitation, is quite limited.

The aim of the scientific colloquium is the demonstration of the current state of the art in seasonal forecasting. This will serve as a basis for developing guidelines for operational
applications within the framework of the Commission for Hydrology of WMO.

Presenters of scientific organisations, water authorities, national hydrological and meteorological services as well as operational water management bodies will give an overview about the current skills and developments of meteorological seasonal forecasts, statistical methods in pre- and post-processing and applications in hydrology.

The colloquium addresses the scientific community, representatives of water authorities, as well as national hydrological and meteorological services, potential users in the water sector, and consulting engineers.

The Symposium will be held in the main building of the German Federal Institute of Hydrology (BfG), Koblenz, Am Mainzer Tor 1, Germany.
