First Announcement of the IAHS symposium on the

Completion of the IAHS decade on Prediction in Ungauged Basins and the way ahead

Delft, The Netherlands, 23-24 October 2012

In October 2012 we celebrate the 90th anniversary of IAHS and the completion of the IAHS decade on Prediction in Ungauged Basins (PUB). The conference will report on the scientific achievements that were made during the decade and the insights that were gained. We also look ahead to identify the major scientific challenges for the coming period.

During the conference we invite contributions from all scientists that have worked on the main themes of PUB to share their conclusions and views on the advances made during the decade and the remaining research questions. The conference has a general part which provides a summary of the PUB decade, presentations on the Synthesis report and the PUB manual, as well as a visionary session on the future challenges. Subsequently there are thematic sessions organised around the 6 research themes of PUB, as listed below.

Please reserve the dates in your diaries. You may contact the convenors of the thematic sessions now if you would like to make a contribution. In due course more detailed requests for papers will be circulated.
