General Description of the Research Project In recent years, a number of flash floods have occurred in Wadi (dry valley) basins located in Egypt and other arid and semi-arid areas. This study aims to propose an integrated Wadi Flash Flood (WFF) management strategy that combines disaster reduction and water resource development measures. In addressing WFFs, it is important to adopt a multiobjective approach that includes both hard measures (e.g. flood storage facilities) and soft measures (e.g. introduction of a forecasting/early warning system that is based on a rainfall-runoff model and development of land-use plans). On the other hand, floods give rise to valuable opportunities to develop new water resources as they support groundwater recharge. Accordingly, in this study, a hydrological model is developed to reproduce WFFs and consider future effects of them based on a climate change scenario. Then, flood water detention facilities are proposed to reduce the damage of WFFs and ensure groundwater recharge. Further, consideration is given to the applicability of trapezoidal CSG dam—a new type of dam invented in Japan. Based on the above, a risk assessment method is developed for Wadi basins and an attempt is made to apply an integrated WFF management model to real society involving central and local governments as well as local communities.
