Capture and retain heavy rainfall in Jordan

The Middle East is particularly affected by climate change effects and extreme weather events, such as droughts and heavy rainfall. In Jordan, repeated heavy rainfall events in recent years have led to flash floods with enormous damages. Minimizing such damages, but also maximizing the benefits of heavy rainfall via improved water retention in one of the most water-scarce countries in the world, is the research topic of CapTain Rain.

The project “CapTain Rain – Capture and retain heavy rainfalls in Jordan” is funded by the German Federal Ministry of Education and Research (BMBF) as part of the funding measure “CLIENT II – International Partnerships for Sustainable Innovation” in the context of the framework program “Research for Sustainable Development” (FONA).

The CapTain Rain project will participate in the 7th International Symposium on Flash Floods in Wadi Systems (ISFF) taking place in Tlemcen, Algeria from 5. to 7. of June. The event is hosted by the Pan African University, Institute for Water and Energy Sciences (PAUWES) and the EOLE Laboratory (Eau et Ouvrages dans Leur Environnement), University of Tlemcen. The 7th edition of the symposium will focus on flash floods and sediment management in wadi systems in the context of climate change. Four contributions were submitted from different work packages of the CapTain Rain consortium.


The „Day of Hydrology“ (Tag der Hydrologie) is an important conference on Hydrology in Germany, Austria and Switzerland. This year it took place in Bochum on the 22nd and 23rd of March and was hosted by the Ruhr University Bochum and the Bochum University of Applied Sciences. Christina Maus from the Koblenz University of Applied Sciences presented a poster on the topic “Modelling flash floods in data- and water-scarce regions like Jordan – a multi-model approach”.


On Monday, 30.01.2023, the second CapTain Rain Stakeholder Workshop was held at the Geneva Hotel in Amman. In addition to the presentation and discussion of the latest research results, a group work was conducted to discuss planning goals for flash flood damage reduction measures in Amman and the early warning chain in Jordan. We thank all participants for their contributions.
