Abstract: Flood management in arid regions presents unique challenges due to limited information and irregular extreme precipitation patterns. This study focuses on identifying runoff generation areas within an ephemeral river in the south of Lima, Peru, with the goal of enhancing flood mitigation strategies such as the identification of buffer areas for flood control. Using a combination of a water balance using remote sensing products, geographic information systems, and field data, key areas prone to runoff and potential flood attenuation were identified. The results highlight critical zones that could serve as natural flood buffers, reducing the risk of downstream flooding. Furthermore, the study explores the implications of land use and topography on runoff patterns, offering insights into the integration of non-structural measures such as buffer zones into flood control strategies.
