Studies on urban flash floods in Saudi Arabia received less attention from scholars due to the low occurrence level while the negative impacts resulting from it are significant. The objective of this study is to examine the disaster management and mitigation of urban flash floods in Saudi Arabia, particularly Riyadh the capital city. A mixed method combining quantitative and desk review was used as the main approach. It was done through an online survey to collect first-hand data while secondary data relied on the literature, statistical and historical records. This study highlights the importance of disaster and mitigation planning to prevent losses from urban flash floods, especially for Riyadh as the Kingdom’s capital. Some recommendations on how to help mitigate property losses by improving the infrastructure and city planning are also presented.
