Article
Full-text available
Current approaches for assessing large-scale flood risks contravene the fundamental principles of the flood risk system functioning because they largely ignore basic interactions and feedbacks between atmosphere, catchments, river-floodplain systems, and socioeconomic processes. As a consequence, risk analyses are uncertain and might be biased. How...

We investigate possible changes in flood hazard over a 77-km² area around the city of Ravenna. The subsidence rate in the area, naturally a few mm year⁻¹, increased dramatically after World War II because of groundwater and natural gas extraction, exceeding 110 mm year⁻¹ and resulting in cumulative drops larger than 1.5 m. The Montone–Ronco river s...

Full-text available
The upcoming Surface Water and Ocean Topography (SWOT) mission will measure water surface heights and widths for rivers wider than 100 m. At its native resolution, SWOT height errors are expected to be on the order of meters, which prevents the calculation of water surface slopes and the use of slope-dependent discharge equations. To mitigate heigh...
