Extreme rainfall intensities will likely increase in the future due to global warming-induced atmospheric moistening (Trenberth et al., 2003). Particularly, a rapid increase in rainfall intensities is projected for sub-daily scales (1-24 hr), primarily owing to more intense convective events (Zhao, Abhishek, Kinouchi, Ang, & Zhuang, 2022). These increases, combined with multiple anthropogenic factors, such as urbanization and land-use change, would likely lead to more frequent and intense rapidly developing (flash) flood events. This prospect of extreme events that occur with little warning can consequentially cause substantial damage to nature and people, including food reduction, infrastructure damage, economic decline, and more water-related diseases (
