In‐channel wood‐related hazards at bridges: A review

PN De Cicco, E Paris, V Ruiz‐Villanueva… - River Research and …, 2018 - Wiley Online Library
In‐channel wood is a key component in fluvial ecosystems; however, transport of in‐channel
wood during floods can create hazards in urbanized areas. Among the main problems is …

Is local flood hazard assessment in urban areas significantly influenced by the physical complexity of the hydrodynamic inundation model?

P Costabile, C Costanzo, G De Lorenzo… - Journal of Hydrology, 2020 - Elsevier
Flood hazard in urban areas is usually assessed by the estimations of parameters like flood
