HALBAN The 3rd International Symposium on Flash Floods in Wadi Systems (ISSF) entitled “Disaster Risk Reduction and Water Harvesting in the Arab Region,” concluded end of last week at the German University of Technology in Oman (GUtech) in Halban. Sessions on hydraulic simulation, water harvesting and sediment management as well as monitoring, meterology, climate change, risk assessment, risk management and hazard mitigation were held.
According to the international experts in the multi-disciplinary field of flash flood management, most Arab countries have been suffering from a rise in flash floods, especially within the past ten years. Dr. Ayisha Al Khatri from the Ministry of Regional Municipalities and Water Resources (MRMWR) gave a presentation on the Hydrometic network and its role in flash floods monitoring in the Sultanate of Oman. Dr. Ayisha said that the first rain gauge was installed in Muscat in 1893 already. The first flood risk studies was initiated in 1987 already. In 1992 the ministry published the first flood risk maps, indicating areas that are located in flood areas. The hydrometic network monitors flash floods and therefore helps to project and prevent future floods in the country.
A team of researchers from Kyoto University (Japan) Dr. Tetsuya Sumi, Dr. Sameh Kantoush and Dr. Mohamed Saber, raised in their research presentation the question regarding the understanding the dramatic changes of flash floods in terms of their frequency and intensity due to climate change and how to mitigate and manage the flood water and to reduce the risk of disasters? For their research they applied water harvesting and hydrological modelling within a case study conducted in Egypt.
Towards the end of the sessions, the participants of the symposium discussed a joint 5year Road Map towards establishing an international framework of guidelines for the management of flash floods in wadi systems. Short-term measures such as training, construction guidelines and a wadi flash flood textbook were discussed. The framework will also include international research projects, international guidelines regarding the management of wadis, continuous monitoring of the wadi systems, modelling of the wadi flows as well as continuous public awareness through education and health services.
More than one hundred local and international experts from Japan, Egypt, Morocco, Saudi-Arabia, Jordan, Iraq and Germany besides other countries, attended the three-day symposium, that included an excursion to the Fulaij Flood Protection Dam in Sur on Thursday as well as a pre-conference training workshop on “Flow and Sediment Transport Modelling in Rivers and Wadi System using TELEMAC 2D and 3D numerical codes”.
The Department of Applied Geosciences (AGEO) at GUtech organized the symposium in cooperation with the Water Resource Research Center in Kyoto (WRRC), the Global Alliance of Disaster Research Institutes (GDRAI) of the Disaster Prevention Research Institute (DPRI), Kyoto University, and the Ministry of Regional Municipalities and Water Resources (MRMWR). Moreover, the symposium is sponsored by Hölscher Wasserbau GmbH, COMSOL Inc., Al Bustan Construction as well as Gulf Lake. The organizers also wish to acknowledge all support received from the Association for Hydro-Environment Engineering and Research (IAHR).
Since 2015 the Symposium on Flash Floods in Wadi Systems was held in Kyoto (Japan) and in Campus El Gouna (Egypt). The next symposium will be held in Casablanca/ Morocco next year. For further details and registration please check out the conference website isff2017.gutech.edu.om
