We would like to remind you that nominations are now being accepted for the 2025 International Hydrology Prize, Tison and Falkenmark Awards.

The International Hydrology Prize is awarded annually by IAHS, with UNESCO and WMO, to two people who have made an outstanding contribution to hydrological science. Two medals are awarded under the International Hydrology Prize: the Dooge Medal and the Volker Medal. Both medals are intended to distinguish outstanding achievements by hydrological scientists but with a different focus. The Dooge medal is aimed at fundamental contributions to the science of hydrology, whereas the Volker medal is aimed at outstanding applications of hydrological science for the benefit of society at large. More information, including the list of previous awards and the nomination process, is available here.

Nominations are also being accepted for IAHS Tison and Falkenmark Awards. The Tison award is granted for an outstanding paper published by IAHS in a period of two years prior to the deadline for nominations. More information, including the eligibility criteria and list of previous awards, is available here. The IAHS Falkenmark Award is for best PhD thesis from a nominee who grew up in and recently performed the PhD work in one or more financially disadvantaged countries. More information, including the list of previous awards and the nomination process, is available here.
