We present results of an observational and modeling study of the hydrologic response of a riparian wetland to controlled flooding. The study site is located in Poopenaut Valley, Yosemite National Park (USA), adjacent to the Tuolumne River. Thi...

The municipality of San Sebastián, considered one of the most prone to natural hazards in Guatemala, was selected as one of the pilot areas of the UNESCO program on “Capacity Building for Natural Disaster Reduction”. The town is located within the Samalá basin, near the active channel of the river, which is heavily affected by lahars related to the active SantiaguitoSanta María volcanic complex...

Abstract The ability to map floods from satellites has been known for over 40 years. Early images of were rather difficult obtain, and flood mapping was thus opportunistic limited only a few case studies. However, the last decade, with proliferation open-access EO data, there much progress in development Earth Observation products services tailored various end-user needs, as well its integratio...

Lidar data have become a major source of digital terrain information for use in many applications including hydraulic modeling and flood plane mapping. Based on established relationships between sampling intensity and error, nominal post-spacing likely contributes significantly to the error budget. Post-spacing is also a major cost factor during lidar data collection. This research presents met...

SAR images of river inundation prove to be very relevant for operational flood management. However, common exploitation of satellite images of floods is generally restricted to a flood extent extraction. The usefulness of these images could be significantly improved by providing a hydraulic-coherent 3-dimensional (3D) characterization of floods and by integrating these Remote Sensing-Derived (R...

This study focused on producing flash flood hazard susceptibility maps (FFHSM) using frequency ratio (FR) and statistical index (SI) models in the Xiqu Gully (XQG) of Beijing, China. First, a total of 85 flash flood hazard locations (n = 85) were surveyed in the field and plotted using geographic information system (GIS) software. Based on the flash flood hazard locations, a flood hazard invent...
